Sheet metal is one of the fundamental forms used in metalworking and it can be cut and bent into a variety of shapes countless everyday objects are fabricated from sheet metal. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter.

Gauge nominal in mm max in mm min in mm 10. Sheet metal thickness is denoted by gauge sometimes spelled gage which indicates a standard thickness before processing. Sheet metal gauge tolerances chart. Sheet metal is manufactured and delivered from the processing mill rolled to the standard thickness that you specify which is now metric.

Sheet metal wire gauge sizes data chart tolerances engineering design limits fits. Gague are used to specify the thickness of a metal sheet.

Processing may include polishing or the applying of protective plastics which will decrease or increase a sheet s thickness respectively.

304 316 409 420 430 cold rolled stainless sheet. Extremely thin sheets are considered foil or leaf and pieces thicker than 6 mm 0 25 in are considered. The sheet metal does however have a tolerance on the rolling thickness which needs to be taken into account when designing a tight fitting assembly especially as the sheet metal material gets thicker. Sheet metal is metal formed by an industrial process into thin flat pieces.

During the rolling process the rollers bow slightly which results in the sheets being thinner on the edges. Sheet metal guage tolerances.
