Tolerance sheet metal gauge.

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 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 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 equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters. Hr hot rolled cr cold rolled sheet metal gage guage size chart carbon steel sheets.

For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter. 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 knowledge menu sheet metal manufacturing and services. During the rolling process the rollers bow slightly which results in the sheets being thinner on the edges. Click here for a gauge to mm conversion chart. Thicknesses can vary significantly.

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. Sheet metal gauges the below table summarizes sheet metal gauge and tolerances.
