Sheet metal is metal formed by an industrial process into thin and flat pieces. It is one of the fundamental forms used in metalworking and it can be cut and bent into a variety of shapes. Thicknesses can vary significantly; extremely thin thicknesses are considered foil or leaf, and pieces thicker than 6 mm (0.25 in) are considered plate. At RPWORLD, our sheet metal fabrication service is designed for rapid prototyping, end-use production and assemblies.
