Common sheet metal fabrication methods

Sheets of material are fabricated using a variety of methods to achieve the desired objectives of a particular project. This guide deals with the most common methods of Sheet Metal Fabrication and advises on the most suitable ways to communicate requirements to a Fabricator to achieve a cost effective solution.

Laser Cutting

Accuracy: Laser cutting offers the highest degree of accuracy on sheet metal, ideal for intricate cuts, holes and other complex profiles. Suitable for: Mild steel, stainless steel and aluminium. Aluminium.

Press Braking

Bending in a press brake: Forming parts and shape of sheet metal by bending in a press brake (e.g. frames, parts of brackets, sheet metal enclosures).

Punching and Stamping

Punching involves using a shaped tool to create holes or other cut-outs in a sheet of metal. Punching is a very fast process and is often used when making a large number of the same part.

MIG and TIG Welding

Welding is used to join pre-fabricated parts to form a complete structure. Most work is carried out using MIG welding but some projects may require the more precise TIG welding, often for thinner gauge metal or for parts that will be seen after completion.

Powder Coating

Finally the finished article is protected against corrosion and wear by a durable, even finish applied by way of powder coating. This could be the final step in the workshop for articles made from sheet metal to be used outside or subjected to heavy use.

By choosing the best method for your job at the design stage, you can save so much time, avoid so much waste and end up with a better design within a budget that suits your needs.
