Custom Sheet Metal Fabrication

What is Sheet Metal Fabrication?

Sheet metal fabrication is a subtractive manufacturing process that forms parts from thin metal sheets. Engineers often choose sheet metal parts for their high precision and durability, especially for end-use applications like chassis, enclosures, and brackets.

Sheet metal manufacturing is suitable for various metals.

  • Stainless steel: Used for its strength and resistance to corrosion
  • Cold-rolled and hot-rolled steel: Both of these are easily formed, but cold-rolled has a smoother finish and tighter size tolerances
  • Aluminum: A lightweight metal with exceptional strength-to-weight ratio
  • Copper and brass: These metals are easy to work with and look good in a fabrication

Custom sheet metal fabrication is the process of customizing metal parts or products to specific standards and needs. This process involves cutting, bending, shaping and welding metal sheets into specific shapes and sizes.

Sheet metal processing refers to processing flat metal sheets into various shapes and structures. The sheet metal processing method is not a single process, but a series of forming technologies that work together to produce the required parts. Metal processing is widely used in the automotive, aerospace and construction industries.

Custom sheet metal fabrication services are used for a variety of applications, including HVAC systems, architecture, industrial production, and decorative enhancements.

What Types Of Sheet Metal Fabrication Are Available?

There are many types of sheet metal fabrication services available, depending on the desired outcome. These can include:

  • Cutting – as it implies, this involves cutting material down to exact length and specification.
  • Forming and Shaping – this is where metal is coerced into a new shape, often through a press brake, or rolling it into a curved form.
  • Machining – in this method, metal is removed from key areas, creating holes and other forms. This is done through various cutting tools, using hardened materials to cut the metal to specification.
  • Grinding and Finishing – Grinding can be used to ensure a smooth, level shape or surface, while additional finishing techniques, such as coating or galvanising, can add the final qualities needed.
  • Punching – this involves using specialised machines to punch shapes directly into sheet metal, creating the desired components quickly. This is ideal for batch orders.
  • Welding – there are a number of techniques, including Mig and Tig, but welding nonetheless serves to join separate pieces of metal together.

Advantages of sheet metal fabrication

  • Durability: Sheet metal is strong and durable, and sheet metal parts can often withstand more pressure and heat than plastic parts. In addition to this, aluminum, stainless steel or surface treated steel are resistant to pressure, corrosion and wear. While methods like casting offer these advantages, the durability of plastic decreases over time.
  • Replaceability: One of the biggest advantages of using sheet metal is that the parts are replaceable. If several metal parts are used to make an assembly, instead of making the whole part out of one substance, the individual components can be removed and replaced without having to replace the entire assembly. This can save money on repairs and even allow for modifications and upgrades.
  • Sustainability: As far as materials go, metal is by far one of the most sustainable materials. Metal is a natural resource that is both environmentally and economically strategic. When the parts are no longer needed, they can be recycled indefinitely and turned into other parts. Plastic has a limited ability to be recycled and cannot be easily and safely disposed once it reaches its end point. Metal manufacturing is a much more responsible and sustainable option.
  • Cost-Effectiveness: Tooling costs for plastics can be very expensive, making sheet metal a more economical choice. Many companies move from cast or molded parts to sheet metal because of the overall reduction in costs and material waste. Material lifespan and longevity must also be considered when evaluating the cost of material. The cheapest material is not necessarily the most cost-efficient option if it will not serve you well for a long period of time and has to be consistently replaced or maintained. The strength and durability features of sheet metal make it a more cost-effective option.
