Custom sheet metal is metal formed into flat thin pieces and can be cut and bent into many different shapes to your specifications. Most everyday objects are constructed of the material. Thicknesses can vary significantly, although extremely thin gauges are considered foil or leaf, and pieces thicker than 6 mm (0.25 in) are considered plate.
The thickness of the sheet metal is called its gauge. The gauge of sheet metal ranges from 30 gauge to about 7 gauge. The higher the gauge, the thinner the metal is. Sheet metal is available as a coiled strip or flat pieces. The coils are formed by running a continuous sheet of metal through a roll slitter.
