Sheet Metal Thickness Gauge Chart

Gague ga is a length measurement unit for diameters originating in north america and belongs to the browne sharpe metering system.

Sheet metal thickness gauge chart. A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters. 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. Gague are used to specify the thickness of a metal sheet. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge.

The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. When working with sheet metal the term gauge is often used. In the us the thickness of sheet metal is commonly specified by a traditional non linear measure known as its gauge. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter.

Sheet metal thickness is denoted by gauge sometimes spelled gage which indicates a standard thickness before processing.

The larger the gauge number the thinner the metal.
