Sheet metal is a core resource used in a variety of industries from construction to engineering. When manufacturing sheet metal, a crucial step is choosing sheet metal finishes. The finish of the metal produced at the end of the sheet metal fabrication process determines what the product can be used for and how it will hold up in different conditions.
In this blog, we’ll use our expertise in powder coating to inform you of the different types of metal finishes available and explore their advantages and disadvantages.
What Are the Different Types of Sheet Metal Finish?
There are a wide range of metal finishes available, but we’ve listed just a few of the most common types of finishes available.
Powder Coating
For this metal finish, a dry powder is applied onto the metal using an industrial airbrush. This process is most commonly used for furniture and appliances, from outdoor metal benches to coffee machines. The custom colours you see on the body of cars are also achieved with powder coating.
Powder coating is a great alternative to paint as it is more durable and resistant to the elements, chemicals and UV rays. Although it is a longer-lasting option to paint, it will begin to peel over time and require recoating or you risk damage to the metal.

Standard Raw Finish
A metal sheet without any finish. This is the product in its raw form and has been left without any polish, sanding or additional coating. Metals have a raw finish if they are already suitable for use in their original form. Typically metals like aluminium, iron and steel can be left with no finish as they are naturally resistant to water damage and corrosion.
A raw finish on metals is a great way to save time and money on additional finishing processes, but it is only suitable for certain metals, making it a process that cannot be standardised across all products.
Electroplating
Electroplating uses the process of electrolysis to add a layer of metal onto another metal. This process can be done with a range of different metals and is commonly used to strengthen a material. Electroplating is a common method in jewellery production where an inexpensive metal is coated with a thinner layer of a more expensive metal like silver or gold.
Buff Polishing
Buff polishing is a finishing process that creates a smooth and shiny surface on metal sheets. The process is mainly used for visual appeal to remove any imperfections in the metal. The metal is buffed using a rotating blade covered with cloth or felt material. Buff polishing is used on products like kitchen utensils to create a smooth, safe and washable surface.
Passivation
This is the process of chemically treating metal alloys like stainless steel to make the metal corrosion-resistant. Metal oxide coats the metal sheet during the finishing process and this delays oxidation to make the material more resistant to rust and corrosion. Passivated metal is ideal for use on outdoor structures and is regularly used in construction.
Hot Blackening
Hot blackening involves dipping metal into a vat of sodium hydroxide and nitrates which turns the metal surface into a magnetite. This process helps to reduce abrasive damage and gives metal a darker colour without paint. Hot blackening is applied to large batches of metal parts and is regularly used to create natural-looking dark metals for things like furniture.
Galvanisation
An ancient but effective method of finishing metal, galvanisation involves coating metal in zinc to create a protective layer against rust and corrosion. During this process, molten zinc is used and metal is dipped into it.
What Are the Best Metal Finishes?
There are a wide range of popular metal finishes but there are three main finishes that are regularly mentioned as the preferred methods.
Best for Diversity
Powder coating is the most versatile process by far, allowing for a protective coat of any colour to be added to a wide range of materials including wood and plastics, as well as metals. Powder coating can be customised to your needs, and when carried out by expert painters at Salamander Fabrications, you can benefit from stain, gloss and matte finishes.
If you want to benefit from custom powder coating services to suit any project, contact one of our experts at 01484 843599.
Best Value for Money
Electroplating is the most recognisable form of metal finishing and is extremely common due to the money the process saves. The process balances high-quality plating with reduced costs, allowing cheaper metals to be coated in a thin layer of more expensive, corrosion-proof coating.
This means companies don’t have to pay hefty prices to make things from solid gold or silver and can instead plate other metals using electrolysis.
Best for Durability
Galvanisation is also deemed a superior finishing process and is regularly used as a low-cost, versatile metal coating method. As well as being fairly inexpensive, the galvanising process makes metal extremely strong and resistant to damage.
Galvanisation also improves the longevity of household items and means customers can benefit from less maintenance and repair on products they purchase.

Typically there are four types of lasers used in laser cutting. Once the laser cuts into a material, gas is blasted onto the heated area, causing the cut to cool and the material to retain its shape as the laser continues cutting through the material.
Laser cutting is a technique used in a wide range of industries from construction to electronics, engineering and even clothing.
Laser Cutting Advantages
Now you have a basic understanding of how this machine works, it’s time to dive into the main advantages of laser cutting.
Powerful enough to cut a range of materials whilst still maintaining accuracy. You can use a laser cutter on most materials including metal, wood, glass plastic and even some fabrics. This makes laser cutters a great choice for use during sheet metal fabrication and a range of other projects.
The versatility of this machine eliminates the need to purchase a range of cutting tools and therefore saves money.
Quality Finish
Due to the high precision of a laser cutter, the cutting process is smooth and there is no need for any additional finishing processes like sanding, smoothing etc. Because the laser is so precise, the integrity of the material you are cutting remains intact and without any burrs.
Quick and Efficient
A laser cutter is an extremely fast cutting tool compared to traditional methods like water or flame cutting, with the ability to have a full piece finished in minutes. The machine’s work rate allows for more efficient working and higher production rates.
Reduced Waste
Because a laser is precise when cutting compared to other methods like manual cutting, there is a reduction in the amount of material waste that typically occurs from things like sawing. This means that in turn you’re able to save material and reduce material costs.
Cost Effective
A laser cutter is an expensive investment initially but the benefits and savings outweigh this cost in the long run. The speed of a laser cutter means faster production at higher volumes whilst the reduced material waste means money is saved purchasing materials.
The automated machine also removes the need for manual labour costs. All of these elements lead to an overall reduction in costs in the long term.
Automation
One of the reasons a laser machine is so versatile is due to its capacity for automation. These machines can be programmed to repeatedly cut the same shape without having to stop or adjust any settings. This means that they’re ideal for larger manufacturers and mass production.
This doesn’t mean that laser cutters can’t be used in smaller settings however, and many small businesses utilise smaller models to create custom engravings, and cuttings.
CAD Compatible
Laser cutting is one of the more advanced forms of cutting as the process is operated by computers. The lasers are programmed to cut a certain shape, and CAD design services can be used to create custom and intricate designs that the laser can then directly cut.
This is a faster and less cumbersome process compared to manual carving, etching or sawing designs into a material.
Cutting Depth
A laser cutter can reach depths of around 12mm, with a standard C02 cutter reaching depths of 10mm. This means lasers are a diverse method that can easily cut through thin metal sheets easily and quickly as well as thicker sheets if needed.
Safety
Laser cutters come with an enclosure and automated safety features to reduce the risk of damage or accidents from interacting with the laser beam. The automated nature of laser machines also means there is a reduced chance of injury to workers as there is no need for manual handling.
Multi-Axis Cutting
Unlike manual or traditional cutting methods, laser cutting can perform cuts that create 3D shapes and complex designs too intricate for processes like cutting by hand.
Scalability
Laser cutters can be scaled to any size so it is easy to create smaller prototypes and large-volume mass-produced pieces with the same machine. This is ideal for companies that need to test their products before they are put on the production line.

Laser cutting accuracy can vary, allowing high-precision cuts in ranges between ±0.05 and ±0.2 mm. The ability to produce such accurate results across various measurements makes the laser cutter an ideal choice when creating indicated designs.
The variable range of a laser cutter also means it can maintain accuracy across a range of materials including textiles, wood, metals and some plastics.
How Can You Maintain Laser Cutting Accuracy?
Whilst laser cutters are extremely accurate on their own, there are some measures you can take to ensure your machine continues to have high levels of accuracy.
Cleaning
Make sure that your machine is regularly cleaned. Wipe away any dust or debris from the laser bed and ensure the ventilation system is clean to ensure any smoke is correctly filtered when the laser is in use. Laser cutting is a primary process used in sheet metal fabrication so it’s important to check for any small shards of metal debris that could cause damage to the machine and operators.
Calibration
Inspect the alignment of the laser beam regularly. Misalignment of poor calibration can affect the accuracy of cutting and lead to the beam being off-centre.
Update Software
The latest firmware and software updates should always be installed to ensure the machine operates at full capacity. Calibrate the machine every few weeks using the provided software to ensure everything is working properly.
Environment Control
The temperature of your workspace should remain stable and at a workable temperature. Fluctuations from temperatures that are too warm or too cold can affect the machinery within the laser cutter and cause performance issues.
Make sure that your working environment is also well-ventilated and free from excess dust as this can settle on various surfaces.
Professional Servicing
Just as you would with any other machinery, annual check-ups and professional servicing are required to ensure your laser cutter is operating correctly. You can also utilise the expertise of professionals to train staff on laser cutting and how to correctly use this machine to keep it well maintained and avoid misuse.
Which Type of Laser Cutting is Most Accurate?
There are four main types of laser cutters. Each type of laser cutter has a different function and is used on different materials.
When it comes to laser cutting accuracy, fibre lasers are deemed the most precise and versatile. Fibre lasers generate a powerful beam that allows them to cut through a wide range of materials including metals, wood, glass and more.
Not only do fibre lasers offer more accuracy but they offer faster cutting times, less material wastage and a smoother finish.
At Salamander Fabrication, we utilise fibre lasers to ensure the most efficient and accurate cutting.
How Does Laser Cutting Accuracy Compare to Other Cutting Methods?
Laser cutting is a great all-around accurate process, but how does it compare to other cutting methods?
Waterjet Cutting
A waterjet cutter uses pressurised water to cut through materials. The water can also be mixed with minerals known as abrasive grains to produce an even more powerful cut that can easily get through even thick metals.
A waterjet is great for metal but this machine is slower than machines like a laser cutter and has a lower laser cutting accuracy when making more intricate cuts or cutting smaller sections of material.
A waterjet is also more expensive to run than a laser cutter.
Plasma Cutting
Plasma cutting is a form of cutting used predominantly on metals. It involves gases that conduct electricity passing through a torch to cut through metals. Plasma cutters are commonly used in the transport sector in auto repair shops.
Similar to a waterjet, this method of cutting is great for thick metal but the process is not as versatile as laser cutting as it can only be used on metal.
A plasma cutter is less accurate, more expensive to run and uses a lot more energy than a laser cutter.
Flame Cutting
Flaming cutting is the process of cutting through materials using oxygen that reacts with heat from a flame. The chemical reaction allows the metal placed below to be pierced and cut through.
Although this process doesn’t involve electricity and saves on energy costs, it is far less accurate and slower than laser cutting. The process can also only cut a limited number of metals like steel.
It’s clear that no matter the benefits other cutting methods offer, laser cutting accuracy is superior and cannot be beaten by any other cutting method.
What Can Impact the Accuracy of a Laser Cutter?
Whilst laser cutters are generally deemed the most accurate type of cutter, there are some factors that can influence the accuracy of your laser cutter.
Machine Quality
As with any product, quality usually equates to the price you pay. If you buy a cheaper machine your laser is likely to be less accurate and of lower quality. Industrial-level laser cutters are known to be expensive, and a high-quality machine will give you the best level of accuracy.
Type of Laser
The most accurate type of laser is a fibre laser cutter. If you choose CO2, crystal or diode lasers they may possess other benefits but at the cost of being slightly less accurate.
Laser Speed
If you want to increase the speed of production, you can increase the speed of the cutting process. The faster the cutting speed, however the less accurate the cut is expected to be. You therefore need to find a balance between speed and accuracy.

What Is Laser Cutting?
Laser cutting is the process of using strong laser beams to melt or burn materials into the desired shape. Gas is blown onto the heated area to cool it as the material is cut which allows it to maintain its shape as the laser continues cutting.
For a more in-depth explanation of the laser cutting process, we have a dedicated page on how laser cutting works.
Materials Used in Laser Cutting
What makes laser cutting such a brilliant cutting method is its versatility and the ability to cut through a wide range of materials with ease. Where other methods may fail or require additional steps, lasers are powerful enough to create accurate, clean cuts through a range of plastics, woods and metals.
There are also different types of laser cutters from CO2 to crystal cutters, each being designed for use on different materials. So what materials can a laser cutter cut?
Metal
Laser cutters are most commonly known for their ability to cut through most metals and are used in industrial settings on a wide range of metals. Laser cutting is in fact a primary process in metal sheet fabrication and has become an industry staple for cutting metals like stainless steel. It’s important to note that although laser cutters have a limited depth, advanced machines can cut up to 50mm. Laser cutters are suitable for these metals:
Steel – Stainless steel and mild steel. This corrosion-resistant metal is heavily used in household appliances and the food industry.
Brass – A versatile metal, brass can be easily melted and is often used to create household pipes and pumps.
Aluminium – A lightweight metal, aluminium laser cutting is favoured in the transport sector and is commonly used in manufacturing aircraft and automotive parts.
Titanium – Extremely strong, lightweight and with a high melting point, this metal is used in a number of industries but is regularly used to provide structural support in the construction industry.
Copper – As a powerful conductor of electricity, copper is most commonly used in wiring but we also see it in our currency with copper coins.
All of these metals are used across a wide range of industries, most notably the construction sector. Laser cutting these metals allows for a fast turnaround of supplies that can be used on building and industrial sites.
Wood
Laser cutters are great for cutting and engraving complex patterns and shapes into wood, and with the help of CAD services, lasers can create a range of beautiful custom designs. Laser cutters can be used with:
MDF – A multipurpose material, with wood is used in house construction, furniture, flooring and much more.
Plywood – Made from birch, bamboo, or beech wood.
Poplar
Balsa
It’s important to note that wood that contains natural sap or resin cannot be cut with a laser cut as this can cause the wood to catch fire.
Plastic
Plastics are by far the most varied material that can be laser cut, with all sorts of plastics being cut to create furniture, industrial parts, kitchen utensils, clothing and much more. Polyethylene is the most common plastic in the world and as such is most frequently used in laser cutting, but you can also cut a range of other plastics including:
Acrylic – A versatile plastic, we see this plastic all around us in beauty products like false nails, furniture, electronic screens and more.
Polyester – Most commonly used in the textile industry, we use polyester to make clothes, bedding, tents etc.
Polyurethane – A foam-like plastic, this is used to provide cushion or padding in furniture as well as in construction for flooring underlay and wall insulation.
Polypropylene – Commonly used in the food and packaging industry, this plastic is used for food packaging, bottles, yoghurt pots and more.
PET (Polyethylene terephthalate) – The clear water bottles we see in every store are made from this material, along with synthetic fibre clothes.
There are some plastics however that should never be used with a laser cutter, but we’ll cover those later on.
Paper and Card
With the wide variety of laser cutting machines on the market today, you’re now able to buy laser cutters for home or small business rather than for cutting on an industrial scale. These machines are perfect for creating cuttings and designs on paper and card and can help make quick work of crafts projects and retail and leisure displays made from:
Corrugated card
Art paper
Corrugated card
Construction paper
Copy and print paper
What Materials Cannot Be Cut with a Laser Cutter?
Whilst a laser cutter is a popular option thanks to the diverse range of materials it can cut, there are still some plastics, metals and wood that are not suitable for laser cutting.
PVC – This is a dangerous material to use with a laser cutter and should never be cut in this way as heating the plastic with a laser causes toxic fumes.
Polystyrene – This foam-like plastic is extremely flammable and should never be used with a laser cutter due to the high risk of catching fire.
Fibreglass – This material is a mixture of glass and epoxy resin, and just like with PVC cutting through epoxy with a laser produces toxic fumes and so this should never be done.
Polypropylene – This plastic tends to melt which makes it difficult to achieve a clean cut. The melting also produces burnt/ discoloured areas on the surface and produces smoke as the material burns.

As kiosk manufacturers ourselves, Salamander Fabrications is here to give expert insight into the increasingly common question: what is a kiosk?
A kiosk is a metal standalone structure, usually seen in public spaces like shopping districts or the entrance to attractions. The purpose of a kiosk is to provide goods or services to a customer. Sometimes they operate by using automation, like in the case of self-serve kiosks, and sometimes are manned by staff.
In this guide, we’ll take you through all you need to know about what kiosks are, how they operate and how they are made.
The first thing to know about kiosks is that there are two key types you will encounter: manned and self-service kiosks. Let’s explain exactly what each of these kiosk types entails.
Manned Kiosks
These are kiosks operated by a person or persons. This is most commonly the case for catering kiosks, where food is served to customers and sometimes also prepared within the confines of the kiosk, by a member of staff.
Burger vans, street food kiosks and coffee carts are all examples of manned kiosks. You might also find them in other scenarios where human interaction with customers has been selected over automation, for example, in ticketing booths.
Self-Service Kiosks
What is a self-service kiosk? A self-service kiosk, as you can surmise from the name, allows a user to serve themselves. This is usually achieved through an interface such as a display screen and a way for the customer to communicate their choices like a touch screen or pin pad.
Consequently, it will also generally have an integrated payment feature that allows for card or cash payment to be made by the customer at the time of purchase
Self-service kiosks are on the rise globally, in part due to how they can help reduce staffing costs for businesses. Datos Insights reports that from the two years up to 2023 self-service kiosks in the restaurant industry rose by 43%, a clear indication of how the world is embracing self-service kiosks.
What Are the Most Common Categories of Kiosks?
Kiosks provide a wide range of services in our daily lives. We can categorise these into several broad types of kiosks below.
Food Kiosks – As you can imagine, food kiosks allow vendors to sell a variety of foods to customers. This can range from hot beverages to street food.
Catering Kiosks – As with food kiosks, catering kiosks are designed for serving food to customers. The key difference is that catering kiosks are equipped for food preparation within the kiosk itself, whereas some food kiosks simply serve pre-prepared food.
Service Kiosks – This kind of kiosk gives the user a specific service or piece of information. Often this means completing a task – like retrieving tickets or checking into a venue – without the need for human assistance.
Vending Machines – You might not immediately have thought of vending machines as a form of kiosk, but they are. They are typically positioned in public places where people might need what they serve automatically.
Other Enclosures – This category of kiosk includes miscellaneous kinds of enclosures that are defined as kiosks. One example would be digital advertising displays which are thought by some to be a kiosk in that they are standalone structures which exist in public spaces, and provide a visual service to users despite not requiring interaction.
10 Different Examples of Kiosks
Until you start to think about kiosks, you don’t necessarily realise how many you see and interact with in public spaces on a daily basis. Let’s take a look at some of the most common ones, as well as some extremely new developments.
1. Wayfinding Kiosks
These problem-solving kiosks are usually dotted around large venues, often shopping centres, to assist people by providing directions. Using a touchscreen, users can enter their desired endpoint and receive specific map instructions on the screen.
2. Streetfood Kiosks
From pop-up food trucks at festivals to burger vans outside football stadiums, catering kiosks are a key kiosk type. Streetfood kiosks offer the ability to prepare and sell food from inside the kiosk. Most often they are easily transportable so that they can be taken to events to trade.
3. Vending Machines
Vending machines are a popular form of self-serve kiosk. They offer franchise opportunities and can make a great investment when placed strategically. The owner will have the responsibility of stocking them and will need to apply for relevant permits in order to install and run one in the public domain.
4. Temperature Kiosks
This form of kiosk is a new development in the world of kiosks since the Covid-19 pandemic. These stands are often found in airports and offices and allow users to have their temperature scanned to check that they aren’t ill before entering a densely populated space.
5. Coffee Carts
Coffee carts are usually movable catering kiosks that serve hot beverages like tea and coffee. They are often portable in order to be placed in popular areas by the vendors. They are a highly common form of kiosk.
6. ATMs
Did you know that ATMs are a common form of kiosk? They require extremely robust casing and tight conformity to the provider’s design and branding. Take a look at the ATM project we completed for Travelex cash machines.
7. Ticketing Kiosks
While ticketing enclosures are occasionally manned, generally they tend to be self-service kiosks. These kiosks allow users to redeem or purchase tickets, often also printing and dispensing the tickets as well.
8. Mobile Device Charging Kiosks
These kiosks are another modern development in the world of kiosks. They allow users to charge their phones for a fee and are usually found in places like airports or train stations for convenience.
9. Photo Printing Kiosks
Photo printing kiosks are a good example of where a kiosk has replaced the need for a business’s staffing costs. Customers can interact with the touchscreen to select their photos and print them on the spot.
10. Package Collection Lockers
This is an increasingly prevalent example of a completely self-service form of kiosk. Customers pick up packages contained within a metal locker in a public location by entering a release code on the touchscreen pad. This unlocks the locker.
What Is A Kiosk Made From?
Kiosks by their nature serve the public wherever they are needed, so it’s normal for them to be positioned outside in all weathers. This is why kiosks need to be robust. Their manufacture requires skilful design and strong materials. Most often metal is chosen as the material for the outer enclosure of a kiosk.
The Make-Up of a Kiosk
Depending on their function, different types of kiosks will have a variety of designs and features. However, the core makeup of any kiosk can be broadly categorised into the following components.
Enclosure
The whole kiosk will be encased in a robust enclosure, usually made from sheet metal.
Control PC
The control PC is the ‘brain’ of the kiosk managing and controlling its functions. It is the CPU which runs the software for the kiosk and connects to and processes the input from any hardware, such as pin pads.
Screen
In most cases, self-service kiosks will have a screen. Where the kiosk sells goods or services the choices will generally be displayed in the form of a user flow menu.
Peripherals
Peripherals include hardware integrations like pin pads, plastic and metal housing and branding etc.
Thermal Printer
Where receipts are given by the kiosk, a thermal printer will be housed inside the enclosure.
How Is a Kiosk Manufactured?
The requirements for how each kiosk is made will differ depending on the complexity of the design. The standard outline is as follows:
Design phase: At Salamander, we are skilled at taking pre-existing designs that conform to strict brand guidelines and creating them to tight tolerances. However, we can also help you with CAD and CAM design services for kiosks.
Sheet metal fabrication: The metal used in the project will require sheet metal fabrication and then manipulation to create the correct components, using laser cutting and sheet metal bending.
Electromagnetic assembly: Electrical parts are typically put into place within the house of the machine using electromagnetic assembly. This allows us to complete the project with every element where it needs to be.

FAQs About Kiosks
Now that we have comprehensively answered the question ‘What is a kiosk?’, here are some extra answers to questions that commonly crop up around the topic.
What does a kiosk mean?
Kiosk is an umbrella term used to describe enclosures which provide goods, services or information to customers. Often they include an interface for ordering and payment, like a touch screen or pin pad in self-service kiosks. The term used to refer to an outdoor pavilion however the meaning has adapted with modern times.
Why are kiosks increasingly popular?
Kiosks allow owners to service customers in a relatively low-cost way. After initial outlay on the kiosk fabrication, they require relatively little input to get started compared to a bricks-and-mortar establishment. For instance, a self-service kiosk will require no staffing costs.
How much does a kiosk cost?
Factors that will influence the cost of a kiosk include the thickness and grade of the materials used to produce it as well as the complexity of the electrical components integrated in the machinery. Every project comes with different requirements, however, we are always happy to get the full details and then provide a clear, no-obligation quote.
If you’re toying with using laser cutting as part of your metal manufacturing process, you might be wondering: Is laser cutting sustainable?
It’s no secret that sustainability is on consumers’ minds and has been an increasing priority in all sectors of manufacturing. At Salamander Fabrications, we utilise custom laser cutting services to meet the needs of our commercial clients, operating fibre lasers specifically.
Consumers being more empowered to find out how their goods are made means that more than ever, people are curious to know what the environmental impact of laser cutting is. So, if you’re interested to know, ‘Is laser cutting environmentally friendly?’, read on. We’ll dive into just how sustainable laser cutting really is.
To find out more about Salamander Fabrications’ laser cutting services, get in touch with our sales team today at 01484 843599.
Why Is Laser Cutting a Sustainable Manufacturing Method?
The key advantage of laser cutting over traditional methods is that laser cutting is highly accurate, especially when operated by experienced professionals who can get the most out of your sheet metal and code extremely efficient laser cutting computer programmes.
To understand why laser cutting is an energy-efficient form of cutting various materials like metal it’s important to understand how laser cutting works. Laser cutting uses thermal heat by focussing a laser beam onto materials to burn through them. This is what’s known as non-contact cutting. This has certain benefits for the cutting process, and in particular, positive implications for sustainability. We’ll take you through exactly how in the next section.
If you’re exploring laser cutting for the first time and would like a more thorough explanation, we dive into the subject by answering the question ‘what is laser cutting?’ in another guide.
The Greener Benefits of Laser Cutting
The laser beam is highly focused, allowing for an enormous degree of accuracy. This accuracy means less wastage. The cuts are clean and precise in most cases.
The way that laser cutting is operated is most commonly through CNC programming and CAD/CAM design. The fact that the designs for the cuts are pre-calculated means that you can get the most out of your sheet metal and create intricate objects.
The majority of the process in most cases is automated. This means that human error is almost entirely eliminated. This dramatically reduces wastage from the results of human error such as cutting imprecisely or scorching.
The laser beam requires less power in order to cut through materials than traditional methods. The reduction in energy expended is a key factor in making laser cutting a sustainable choice.
So, in answer to the question ‘Is laser cutting sustainable?’ – the answer is a clear yes, compared to older methods like CNC cutting. However, when exploring the most common types of laser cutting, we established that while the output from laser cutting is similar, the different laser cutters used to produce these results differ.
They differ in aspects like the fuels they run on, how accurate they are, how energy efficient they are and how often they need to be maintained or ultimately replaced. These are all factors in how sustainable they are.
What Is the Most Sustainable Kind of Laser Cutting?
At Salamander we use fibre lasers instead of C02 lasers because they do not require the same level of gas fuel to run and they are a lot more energy efficient in general. Energy efficiency is one of the key metrics to consider when assessing how sustainable laser cutting is.
What Makes Fibre Laser Cutters the Most Sustainable?
Fibre laser cutting works by delivering a concentrated beam of light through a doped optical fibre. There are several reasons why fibre lasers, compared to other types, are the more sustainable choice. These are key reasons why we opt to use them in our sheet metal fabrication and cutting process, here at Salamander Fabrications.
The reasons fibre laser cutters are more sustainable than other lasers are:
They deliver a strong amount of power for the energy they take to run
They require less energy to run the laser than other forms of laser
They don’t require any gas to run, unlike C02 lasers, for instance
They require little maintenance compared to other lasers and last for a long time
Some lasers that run by utilising gases can release contaminants when they interact with the materials they cut – with fibre lasers these emissions are eliminated as they do not use gas
Is Laser Cutting Sustainable in General?
While fibre lasers might be the most sustainable option when considering all factors involved, laser cutting in general is a much more sustainable option than the traditional methods of cutting metal that are notoriously energy inefficient.
Before laser cutting became prevalent in industrial materials cutting, the main methods of cutting through materials on an industrial scale were:
CNC Cutting
Oxy-Fuel Cutting
Plasma Cutting
Water-Jet Cutting
Mechanical Cutting Machines
All of these methods are far more intensive in their use of energy, as well as other resources like water and gases.
So regardless of which laser cutter you opt for, you’re choosing an efficient and modern method of materials cuttings.
Why It Might Matter to You If Laser Cutting Is Sustainable
If your company is producing or retailing goods containing metal components, the environmental impact of laser cutting should be on your mind. Here are a few key reasons why making your metalworking more sustainable might matter to you:
You are working with a third party who has sustainability commitments you need to adhere to – B Corp registered businesses, for instance, have to adhere to a higher level of transparency and accountability about their business sustainability practices to gain and keep their accreditation
You want to produce goods and demonstrate your commitment to sustainability as a unique selling point to consumers – As McKinsey and Neilson IQ found in their consumer insights report, 78% of consumers say that a sustainable lifestyle is important to them. This research also supports that consumers are willing to pay more for greener products – up to 28% more, in fact.
You have your own business sustainability commitments and want to invest in greener practices – Businesses who make commitments to reducing their carbon footprint can meet their goals by adopting new, more sustainable manufacturing. For instance, by making changes like using laser cutting over higher impact processes.
You’re changing processes in line with carbon reduction targets – As the government starts to target high-energy industries to achieve carbon reduction targets for 2050 many manufacturers are aware that there is increasing pressure to implement sustainable manufacturing processes.
If any of these reasons jump out to you as being beneficial for the future of your metal manufacturing processes, Salamander Fabrications can help you switch to laser cutting. We provide commercial laser cutting services to a wide variety of industries.

FAQs about the environmental impact of laser cutting:
We’ve put together some FAQs to help answer some common questions about sustainability in laser cutting.
Does laser cutting use a lot of energy?
The amount of energy used in laser cutting generally depends on which laser you are using. Some will expend more than others. As we have discussed, fibre lasers are currently the most energy efficient option. However, when you compare all laser cutting to traditional methods using heavy mechanical cutting machines, it is dramatically more energy efficient.
Are laser cutting fumes toxic?
This will depend largely on the material being cut. At Salamander the majority of our work, due to being sheet metal fabrication experts, is with metals. The possibility of metal cutting releasing toxins is generally low, except for situations in which the metal has a coating.
Can you reuse the scrap produced by laser cutters?
Yes, the scrap metal produced by laser cutting machines can be recycled. This is an example of a closed-loop system in which waste is almost entirely eliminated.
If you’re contemplating aluminium laser cutting, consider this your complete guide to understanding exactly why and how laser cutting is the right choice in many cases.
Aluminium is a metal with some unique properties that make it a great option for particular industries. Not only is it lightweight, non-toxic, resistant to corrosion and heat as well as a good electrical conductor – it’s also generally considered an affordable metal due to its relative abundance.
Aluminium is a highly reflective metal, making cutting with any laser challenging, as it can cause burning, ruined sheet metal and potential safety concerns for the operator such as eye damage. We advise that inexperienced laser operators never tackle reflective surfaces. However, all of our staff wear protective equipment and are highly trained and able to manage these risks. In fact, fibre lasers mostly use automated processes via programming, eliminating many of these safety risks.
Which industries can benefit most from aluminium cutting?
In a variety of industries aluminium is a go-to choice for parts which require a lightweight, heat-resistant, high-strength and versatile material, hence why it’s sometimes even called the ‘miracle material’. This often means parts need to be made to intricate, finely calibrated specifications. This is why laser cutting aluminium becomes the ideal choice to produce metal parts, as it can quickly produce extremely precise results.
Here are some examples of key industries which can benefit significantly from aluminium laser-cut parts:
Computing – Aluminium is often chosen for computer components due to its lightweight and particular ability to dissipate heat which helps with portability and heat reduction in computers.
Electronics – As with computing, the heat reduction properties of aluminium make it ideal for use in electronic devices with electrical enclosures which require heat sinks and as an electrical conductor.
Automotive and Aerospace – Aluminium is widely used in the transport industry to manufacture lightweight, high-strength components such as chassis and fuselage parts.
Consumer Goods – Aluminium is extremely durable, making it an ideal material for home goods like appliances, decorative accessories and furniture.
Which kind of laser is best for cutting aluminium?
Both fibre lasers and C02 lasers are the two main types that are predominantly used for laser cutting aluminium in sheet metal fabrication. Different businesses will have different preferences based on the thickness and speed of the job at hand.
The benefits of using C02 lasers for cutting aluminium
C02 lasers operate by inciting carbon dioxide molecules to produce a powerful infrared light beam which can be used for metal cutting and engraving.
The key benefit of C02 lasers compared to fibre is their ability to cut thicker sections of metal. This gives them the ability to work on thick metal-cutting projects. While it can produce a powerful laser beam, it operates on gases which must be replenished and is less energy efficient than its fibre counterparts. They are also notoriously finicky machines which require constant maintenance and calibration.
The benefits of using fibre lasers for cutting aluminium
Fibre lasers get their name from the use of optical fibres. They operate by passing the laser beam through fibreglass diodes, which amplify it.
It also has other clear benefits:
Fibre lasers are a strong a precise method of metal cutting delivering a smooth cut
They are also fast, allowing them to tackle a higher volume, making it ideal for commercial use
Fibre lasers require far less maintenance and have longer service lives than other types of laser-cutting machines, meaning consistent results and little downtime
As they produce less wastage than C02 lasers and need less general maintenance, fibre lasers are more cost-effective
One of their key limitations compared to C02 lasers is that they can only be used for thin and medium-thickness metal sheeting, whereas C02 lasers can handle slightly thicker metals. However, this is rarely a limiting factor for projects.

FAQs about Laser Cutting for Aluminium:
What’s the thickness limit for laser cutting aluminium?
The maximum laser-cutting aluminium thickness will depend enormously on the softness and density of the metal as well as the wattage of the laser.
What wattage do you need for a fibre laser in order to cut aluminium?
Our lasers operate at 3kw and 6kw.
What exactly is laser cutting and what does it entail technically?
So, how do laser cutters work? In essence, laser cutting uses an intensely focused laser beam to cut materials such as sheet metals down to exact sizes and specifications. Other methods exist, such as CNC in which pre-programmed computer software controls machinery which in turn uses contact to carve out the pre-programmed design. Lasers are non-contact, meaning they use a beam of thermal heat to do the cutting.
How much does laser cutting aluminium cost?
This will all depend on factors such as the product being cut, the thickness of the aluminium, the quantity and the turnover. Speak to us today to discuss your needs, so we can provide you with a quote.
Many businesses involved in preparing food will rely heavily on food grade stainless steel. Using this type of metal, we at Salamander Fabrications make various equipment and instruments for our clients in the food and catering sectors.
So, what is food grade stainless steel? Essentially, it is a form of steel that is resistant to corrosion, wear and tear, and leaching in ways that make it ideal for food preparation. These are the properties that make it food-safe. There are several different types available that have slightly different formulations for unique catering purposes.
You can find out everything else you need to know by reading this guide, put together by trusted metalwork experts.
Food Grade Stainless Steel Explained
We regularly provide the food industry with sheet metal products. In the more than 50 years that we have been in business, we have extended our remit to supplying a broad range of sectors and businesses with items made from:
However, stainless steel is particularly often in demand among food businesses looking to fit out commercial and industrial kitchens with the likes of sinks, storage units and worktop surfaces.
This begs the question: what is food grade stainless steel specifically? Essentially, the term refers to any type of stainless steel known to be safe to use with food.
The rest of this easy-to-understand but comprehensive guide will explain the specifics of what it is and how it is used.
What Is It Used For?
The name itself refers to the various forms — or ‘grades’ — of stainless steel which subtly differ in their properties. Generally, though, it can be used for:
Cooking: This is because the metal is ‘non-leachable’, meaning that it won’t compromise how dishes taste.
Preparing food: As some foods — like curries and sauces — are extremely acidic, it is convenient that this metal is corrosion resistant.
Sustainability: Did you know that stainless steel is wholly recyclable? It’s also extremely durable compared to other synthetic materials. As a result, using it can help your business to meet environmental goals.
How Is It Made?
Stainless steel is an alloy made of numerous metals — including iron, chromium and nickel. These constituent metals are sourced from rocks.
For the consequent steel to count as stainless steel, it must contain more than 10.5% chromium. Generally, though, the chromium concentration has to exceed 14-18% for the stainless steel to reach a ‘food grade’.
Mother Nature handles the rest of the manufacturing process, as when the chromium reacts with air or water, a passive but protective chromium oxide layer will form on the stainless steel’s surface.
The Benefits: Why Use Food Grade Stainless Steel?
As we have previously alluded to, exactly what benefits you gain can very much depend on what specific grade the particular steel is. However, common plus points of this steel include:
Heat resistance: This is a prerequisite for stainless steel to be classed as ‘food grade’, and allows the metal to be safely used for handling hot food.
Long lifespan: Products can remain in good condition for some time due to being resistant to chipping and rusting.
Easily cleanable: Another appealing property is its smooth, non-porous surface, which makes it quick and easy to clean.
The Key Types of Food Grade Stainless Steel Available
By tweaking exactly how much of each element the metal contains, we can subtly modify its properties. This enables us to create sheet metal products tailored to suit specific applications.
This particular food safe metal is available in a wide range of grades each represented by a three-digit number. Though most of these stainless steels come in grades starting with a 3 or 4, the key grades are as follows:
SS316
This grade of stainless steel is chosen for many different products — like containers, sinks and pipes — that come into contact with food.
With its chromium content of 18% and nickel content surpassing 10%, this austenitic stainless steel is highly rust resistant. It is also chemically resistant to salt as well as strongly acidic foods, e.g. lemon and tomato juice.
Like other stainless steel alloys, SS316 can withstand temperatures much higher than what would usually be required at many stages of food processing.
SS304
The vast majority of companies in the food processing industry are likely to be able to benefit from the renowned affordability of 304-grade stainless steel.
This corrosion-resistant metal can hold up well when exposed to numerous oxidising agents — allowing it to be sanitised with ease. Many of your workers could come to especially appreciate this when working packed shifts.
Also, you can trust us with welding SS304 sheet metal particularly effectively — making it a great choice for such products as dishwashers and storage tanks.
SS430
Though SS430 food grade stainless steel has the same amount of chromium as the SS316 alternative, the former has far less nickel. This all means that SS430 is the most cost-effective option of the lot.
This — along with its impressive resistance to organic and nitric acids — often makes SS430 the go-to material in situations where the product is expected to long remain in contact with compounds containing such acids.
It would also be worthwhile for you to consider SS430 if you are particularly concerned about the risk of corrosion cracking.

Understand The Key Types Of Laser Cutting
The two types of laser cutting you are likely to hear about most often are CO2 cutting and fibre cutting. Our custom laser cutting service uses fibre cutting.
This is because we ultimately deem it more effective than many alternative approaches to laser cutting — including crystal and direct-diode techniques.
In this article, you will be able to easily pick up comprehensive details about:
Different types of lasers used for cutting
These lasers’ use cases, strengths and weaknesses
Essentially, laser cutting works by focusing a laser beam on a given material, in the process reshaping or distorting it with heat and pressure. If you want a deeper understanding of exactly how we achieve this, get up to speed with our answers to the question ‘what is laser cutting’ before you read on.
Co2 Lasers
These are sometimes referred to as gas lasers, as they produce light beams by running a mixture of gases — including carbon dioxide, but also potentially nitrogen, helium and hydrogen — through a tube.
This type of laser is most often used on relatively thin materials like paper (e.g. wallpaper), fabric, leather and wood.
Though CO2 lasers do not tend to be applied to metals, they remain generally capable of piercing thin sheets of non-ferrous metal, such as aluminium.
Benefits
Can cut a wide range of thin materials
Also useful for processing food like cheese and chestnuts
Can cut through various thicknesses at the same (or lower) power
Do not leave irregularities in material cuts
Also suitable for boring and engraving
Impressive energy efficiency
High power output ratio
Cost-effective
Some CO2 lasers can deliver multiple kilowatts of power
More oxygen can be added to the CO2 beam to strengthen it
Weaknesses
Not suitable for cutting thick metal sheets
Using it to cut metal might lead it to spark or catch fire
Metal cutting jobs can damage the mirrors attached to the tube
Typically limited to 25 to 100 watts of power
Adding more oxygen to the CO2 beam can be risky
This oxygen can potentially catch fire
Fibre Lasers
We use fibre lasers as standard for a wide range of sheet metal fabrication jobs. Fibre lasers are so-called as they work using optical fibre and operate by sending the laser beam through fibreglass diodes, which also amplify it.
Fibre lasers deliver a lot of power for the electricity expended. These lasers can also cut both metallic and non-metallic materials – for example, plastic, glass and wood.
A fibre laser is also the best type of laser for cutting reflective materials, as there is no danger of the laser being reflected off the material.
Benefits
Capable of delivering consistently strong beams
Can achieve extremely precise results compared to CO2 cutters
Can cut more smoothly, quickly and flexibly than CO2 cutters
Much more energy efficient than CO2 cutters
Produce less waste than CO2 cutters
Do not require any flow of gas
Generally do not entail any maintenance
Have a far longer service life than CO2 and crystal lasers
Weaknesses
Usually the most expensive laser cutting machines
Some fibre laser cutters can struggle to effectively cut materials thicker than 20mm
Many fibre laser cutters come with various settings potentially confusing to people inexperienced at laser cutting
Crystal Lasers
Crystal laser cutters can be sorted into the following two broad categories:
Neodymium-doped yttrium aluminium garnet (Nd:YAG)
Neodymium-doped yttrium ortho-vanadate (Nd:YVO)
Each of these terms refers to a specific type of crystal used by the laser machinery — with Nd:YVO crystals being used more often.
Nd:YAG and Nd:YVO units can be compared across a range of measures. For example, while Nd:YVO lasers are broader in bandwidth and higher in thermal conductivity, Nd:YAG lasers last longer and allow for higher pulse energies.
Crystal lasers are used in numerous sectors — including manufacturing and the medical industry.
Benefits
Can cut through relatively thick and tough materials
Offer extremely high cutting power
Can operate continuously
Nd:YVO and Nd:YAG cutters often perform similarly to each other
Also good at cutting a number of non-metals, e.g. plastics
Can cut a few ceramics (albeit only in particular circumstances)
Weaknesses
Can be costlier to buy than other laser cutting machines
Have a low expected service life of 8,000 to 15,000 hours
Rely on pump diodes that can be expensive to replace
Can be less serviceable than alternative laser cutters
Nd:YVO lasers can only run continuously when on medium or high power
Direct Diode Lasers
Here’s a simple question: how does a laser work? Basically, it starts working by using an electrical discharge to stimulate what is referred to as a ‘lasing material’.
All the while, this lasing material is kept in an enclosed container. It is not until after the lasing material is stimulated that the laser cutting machine creates the laser beam — and uses optics to direct it onto the workpiece material.
A direct diode laser is a type of solid-state laser, as its lasing material is in solid form, rather than, say, gas or liquid form. A glass rod in a direct diode laser is doped to bring about the laser action.
Benefits
Uses familiar (and so tried-and-trusted) laser cutting technology
Already mainly used for cutting metal
Some direct diode lasers can tap into multiple kilowatts of power
Produce poorer laser beams in comparison to fibre lasers
Are usually not as powerful as other models of laser cutting machine
Typically only deliver about 10 watts of power
How Do You Choose the Right Type of Laser for Your Project?
Contrary to popular belief, laser cutting is not a ‘new’ technology, as its genesis can be traced back to roughly the 1960s.
However, as many different types of laser cutting machine have since been built, you could struggle to select the right one for your metal fabrication project.
Below, we compare the properties and advantages of various laser types to assist you in matching the right laser cutter to your specific metalworking job.
Cutting vs Engraving
Laser cutters are mainly used for either cutting or engraving. So, before choosing a laser cutter, decide which of these two processes you need.
Another factor is how the material will react to the process. If you seek engraving, for example, you should go with a cutter built for the required precision.
Performance
While somewhat low-power equipment might suffice for laser cutting on a hobbyist level, what if you need to have metal cut for manufacturing purposes? In that case, you might require a cutter high in penetrative power.
However, a bigger factor in a laser cutter’s performance is its optics. So, pay more attention to a cutter’s optics than its power consumption.
Bed size
How much metal cutting or engraving work needs doing, and for what deadline? Your answers will very much determine what size of bed you should choose for the laser cutter.
It’s a simple equation: the larger this bed, the larger the amount of work the cutter will be able to complete at a time. So, for metalwork jobs that need to be finished both quickly and in high quantities, a laser cutter with a large bed would fit the bill.
What materials can laser cutting be used for?
As laser cutters can pierce any kind of metal, they serve crucial purposes here at Salamander Fabrications. These metals can be used on metals including:
Can lasers also cut plastics? Yes, some plastics — but others can be dangerous to cut in this way, e.g. due to gases they would release.
Salamander Fabrications’ Precision Lasers
By investing heavily in our equipment and staff training, we can steer laser cutting projects to success every time. This dedication means that clients can always look forward to seeing great results in line with the brief.
Here are a few examples of what we do to safeguard our high standards:

Has your curiosity been piqued by CNC punching? Perhaps you have only recently heard of this metal fabrication process for the first time, and want to understand it better.
Alternatively, you might have heard about CNC punching before but are unsure what its practical applications and advantages are for your business. We explore all of that here.
Since starting out in Huddersfield more than five decades ago, we have established Salamander Fabrications as sheet metal fabrication experts — and one of the UK’s most trusted choices for welding.
Our services also include powder coating and electro mechanical assembly. As a trusted source of information on metal fabrication, we have prepared the following guide to everything you need to know about CNC punching.
What Exactly Is CNC Punching?
CNC punching is essentially a sheet metal manufacturing process undertaken with the use of CNC punch presses. These CNC machines can be sorted into the following two broad categories, depending on the unit’s design:
Single head and tool rail
Multi-tool turret
The ‘CNC’ stands for ‘computer numerically controlled’. This refers to how software is used for programming the punch press to appropriately position a metal sheet in preparation for punching a hole or form into it.
In tailoring how you set up the machine, you can enable it to punch shapes of your choosing and so help you create simple or complex sheet metal parts.
Benefits of CNC Punching
With a CNC punching machine, designs and any materials you need to produce the parts you require, you can harness the following benefits:
A high level of customisation: In programming the machine, you can ensure it uses precise coordinates to punch the specific shape you need.
Time efficiency: The above coordinates can constitute a ‘template’ for use in speedily producing multiple copies of the same piece.
The ability to create pieces in many different forms: These include beads, louvres and countersinks — none of which a laser cutter could produce.
Reduced waste: The precision with which a CNC machine cuts out shapes means that more of them can be fashioned from a single sheet.
CNC Punching Glossary to Get You Started
As you get started with CNC Punching you’ll notice that there is a lot of specialist language to take on board. For this reason, we’ve put together an easily digestible glossary of terms used around CNC punching.
CNC Punch Press
A specialist type of electromechanical device that securely holds a sheet of material while punching holes or forms into it. The desired design is programmed into the machine beforehand.
CNC Program
A digital set of instructions fed into a CNC machine to direct it to construct a component of the required design. The CNC program can be provided in either a 2D (DXF or DWG) or 3D (Computer-Aided Design, or CAD) file format.
Cluster Tool
A tool that can be affixed to a CNC machine to enable it to punch many more holes in one go. A cluster tool can come with multiple separate punches allowing thousands of holes to be punched each minute.
CNC Engraving
Engraving carried out with a CNC punch press. The engraving design can be programmed into the machine beforehand. This allows — for example — names and numbers to be engraved on individual products and components.
Types of CNC Punches
There are many different types of CNC punch press, and which of them you ought to use will depend on the demands of the project at hand.
Here is a short guide to some of the most popular CNC punches you may encounter and their intended purposes:
Single Head Punching Machines
You might have often seen these described as having a ‘single head and tool rail’ design.
With these CNC punch presses, just one tool is inserted into the punching head at a time. Meaning that the tool can be fully rotated while in place.
Multi-Head Punching Machines
Otherwise referred to as ‘multi-tool’ or ‘mould’ CNC machines, these hold multiple tools simultaneously, with each one kept in a set position in a circular turret.
As this type of CNC punch press is capable of holding three to four rotational tools, along with dozens of additional tools, you would be able to quickly produce large numbers of holes and forms in a wide range of shapes.
Hydraulic Punch Heads
A hydraulic CNC punch press functions by using a pump to run liquid through a hydraulic pipeline and into the machine’s cylinder or piston. The hydraulic system regulates the degree of pressure exerted on the cutting tools.
Complex Contour Tool Rail Systems
CNC punch presses can be relied upon for contour cutting where intricate shapes are cut out of materials including foam and rubber.
Perfect CNC Turrets for Complex and Rotation Axis Tasks
CNC machines in this category can combine a hydraulic punching head with a rotation axis for any tools you wish to secure to the punch press.
Materials Suitable for CNC Punching
CNC punching is an ideal sheet metal manufacturing process for thin sheet metals, as well as other materials of similar thickness. As a CNC punch press can typically machine thicknesses from 0.5mm to 6mm, any material in this range can usually be CNC punched.
That leaves you with many different options when it comes to compatible materials. Naturally, though, these will still vary in their strengths and weaknesses and, as a result, which applications they can be best used for.
Here are several examples of materials you could consider incorporating into CNC creations, such as for different types of health and safety careers.
Stainless Steel
With its impressive strength, corrosion resistance and ease of maintenance, stainless steel is often used in medical settings. For instance, as for handrails and wheelchairs.
It is also used for sterilisable surgical instruments, as it will not corrode in extreme temperatures.
Aluminium Alloys
One such example is aluminised steel, which combines aluminium with carbon steel. This provides the former’s corrosion resistance and the latter’s high strength in one single alloy.
Aluminised steel has long been used for manufacturing kitchen appliances, due to their need to withstand high temperatures.
Brass and Copper Alloys
Brass combines copper and zinc — and those constituent parts’ proportions can be altered to affect the overall alloy’s exact properties.
This helps to explain the sheer versatility of brass — which, being softer than many other materials, is also easier than them to puncture.
Other Metals and Alloys
Titanium has a high strength-to-weight ratio and is often chosen for the production of construction elements.
CNC punching may also be used on high-strength steel that, comprising steel and other elements like copper, carbon and manganese, is well-suited to military armour plates.
LED Panels
LED panels can — due to their perforated features — be made especially quickly with CNC machines using cluster tools that punch multiple grid holes simultaneously.
