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. The following sheet metal gauge size reference chart gives the weight and thickness of sheet metal given as a gauge sometimes spelled gage and indicates the standard thickness of sheet metal and wire for most materials as the gauge number increases the material thickness.

For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter. During the rolling process the rollers bow slightly which results in the sheets being thinner on the edges. Sheet metal thickness is denoted by gauge sometimes spelled gage which indicates a standard thickness before processing. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.

The tolerances in the table and attachments reflect current manufacturing practices and commercial standards and are not representative of the manufacturer s standard gauge which has no inherent tolerances. Sheet metal is metal formed by an industrial process into thin flat pieces. Extremely thin sheets are considered foil or leaf and pieces thicker than 6 mm 0 25 in are considered. Sheet metal gauge size chart gauge or gage sizes are numbers that indicate the thickness of a piece of sheet metal with a higher number referring to a thinner sheet.
