Sheet metal fabrication is the process of turning flat sheets of steel or aluminium into metal structures or products, by cutting, punching, folding and assembling. Sheet metal can be cut, bent or stretched into nearly any shape, which is generally done by cutting and burning the metal.

Special tools, such as band saws and chops saws, can also be used in the sheet metal fabrication process. These ensure even cutting throughout the process. Cutting torches are capable of cutting large sections of sheet metal with minimal effort.

Sheet metal fabrications use press brakes, which ease the process of sheet metal fabrication, by helping to create sharp bends and angles within the metal. There are a variety of different press brakes, which have different functions and are used for different purposes.

One of the other main factors in sheet metal fabrication is welding. Once all the components are formed, they are then assembled and tack welded into position. Many welding techniques can be used in sheet metal fabrication in order to prevent warping or any other abnormalities. These techniques include covering the metal with sand during the cooling process, special straightening process, welding in a staggered manner and using a stout fixture.

Straightening defected metal can be achieved by using with an oxy-acetylene torch. Heat is applied to the metal in a slow manner to remove any abnormalities.

The metal is usually finished by being sand blasted, primed and painted. This then ensures the metal looks fantastic and then is ready to be sent to the client.
