20 Facts About Sheet metal

Sheet metal'set metal is metal formed into thin, flat pieces, usually by an industrial process.

Sheet metal'set metal is one of the fundamental forms used in metalworking, and it can be cut and bent into a variety of shapes.

Sheet metal'set metal is available in flat pieces or coiled strips.

In most of the world, sheet metal thickness is consistently specified in millimeters.

Parts manufactured from sheet metal must maintain a uniform thickness for ideal results.
