Sheet metal fabrication is a general term for the process, but there is more than one type of sheet metal fabrication, each with their own strengths, weaknesses, and uses. In this piece we set out to explain the differences between the different forms of sheet metal fabrication, the different metals used, and how to choose the right sheet metal for your project.
Sheet metal fabrication is the manufacturing process by which sheet metal is processed to create parts and shapes. Sheets of metal are coerced into different shapes using a range of techniques including bending, rolling, punching, cutting, and welding to create new forms.
Occasionally this is the end of the process, and the resulting metal shape is the finished article. But most of the time products created by sheet metal fabrication go on to become a component in a larger product.
It’s important to choose the right sheet metal for your project depending on the end use. Each has unique characteristics that will make it more, or less suited to job at hand.
For example, what are the most important aspects of the metal for your project?
Stainless steel is a common sheet metal used in a wide range of applications across many industries. From kitchen appliances to parts designed for use in airplanes, stainless steel can be found just about anywhere you care to look.
Stainless steel is a popular choice for contract manufacturing due to its unique properties. It is easy to weld, strong, hygienic and corrosion resistant. Stainless steel has a more pleasant aesthetic than many of its counterparts, which makes it a great choice for application where it can be seen, for example in its use in architectural finishes, kitchen appliances and equipment casings etc.
Stainless steel is also known for its ability to withstand very high temperatures. Another common use for it is in kitchen equipment such as pots and pans, and even as part of or all of the kitchen itself. Thanks to its natural hygienic properties, most surfaces and equipment used in commercial kitchens are usually made from stainless steel. This includes work surfaces, ovens and hobs, flues and vents, cutlery and more. The same applies to medical environments and equipment where stainless steel is used in the surgical instruments being used right through to implants and prosthetic components.
Carbon Steel often referred to as CR4 mild steel is an iron-carbon alloy available in low/mild, medium and high carbon steel. It is used in a wide range of applications, many of them on a large scale such as for use in buildings, bridges, and pipelines.
Carbon steel is known for its malleability and environmentally friendly attributes. It is easily recycled making it an attractive choice to any industry looking to reduce their impact on the environment, or to produce items which help the end user do so. Carbon steel is a popular choice for contract manufacturers due to its workable nature, making it easy to handle and fabricate. Available in a range of hardness and strength levels, carbon steel can be used for a wider range of contract manufacturing and fabrication applications than most other metals.
Tool steel is a particular carbon and alloy steel popular in the manufacturing of tools.
There are six distinct types of tool steel:
Tool steel is not only the best choice for contract manufacturing tools, but it can also be the optimal choice of metal in a range of other sectors including healthcare and mould work. Speak to your contract manufacturer about the best choice of metal for your fabrication project.
Regular steel will rust when exposed to the water or moisture. Galvanised steel is ordinary steel which has been coated in zinc to create a corrosion resistant layer, allowing it to be used in outdoor settings and where exposure to damp or wet is expected.
The main benefit of galvanised steel is its ability to withstand damp or wet environments, extending both the possible uses and the life of the material. It is a cost-effective material and offers long and reliable performance. Galvanised steel is low maintenance too, making it a firm favourite for metal fabrication contract manufacturing.
Galvanising provides a tough and permanent coating to the steel which is easy to clean, robust and enduring. It is also lower in cost when compared to other types of coating however, in general Stainless Steel is more resistant to corrosion than galvanised steel and is easier to work
Aluminium steel is sheet steel which is coated in aluminium, or an aluminium-silicone alloy. It is commonly used in applications involving exposure to high temperatures and damp environments. It can be found as part of kitchen equipment, barbeque set ups, exhaust systems and water heaters.
Contract manufacturing projects based around automotive and cookery/kitchen-based products will often use aluminium steel. Maintaining a high strength and longevity in corrosive environments, plus its low price compared to high-alloy steels makes it an effective and economical choice for sheet metal manufacturing projects.
Stainless steel combines the features and benefits of a number of other metals commonly used in contract manufacturing and is a strong and cost-effective material to work with. Offering a wide range of applications from hospitality to medical and industrial to safety, stainless steel is a great choice for many contract manufacturing projects.
The key benefits of using stainless steel in contract manufacturing include:
