Tolerance Sheet Metal Gauge

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.

Tolerance sheet metal gauge.

Thicknesses can vary significantly. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter. 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. Sheet metal thickness is denoted by gauge sometimes spelled gage which indicates a standard thickness before processing.

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. Sheet metal knowledge menu sheet metal manufacturing and services. Sheet metal is metal formed by an industrial process into thin flat pieces. The following charts give typical astm and ansi steel sheet mechanical tolerance ranges.

The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. Processing may include polishing or the applying of protective plastics which will decrease or increase a sheet s thickness respectively. Sheet metal gauges the below table summarizes sheet metal gauge and tolerances. Click here for a gauge to mm conversion chart.

Extremely thin sheets are considered foil or leaf and pieces thicker than 6 mm 0 25 in are considered. A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters.
