Gauge dimensions sheet metal.

Gague ga is a length measurement unit for diameters originating in north america and belongs to the browne sharpe metering system. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. Sheet metal gauge thickness chart. The comparison of different unit systems is shown in the table below.

A sheet metal gauge sometimes spelled gage indicates the standard thickness of sheet metal for a specific material. It is also used to indicate thickness after promotion. As the gauge number increases the material thickness decreases. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.

There is no conversion formula due to the difference between ga. In most of the world sheet metal thickness is consistently specified in millimeters. The larger the gauge number the thinner the metal. Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness.

The larger the number of gauge is the smaller the diameter is. Sheet metal knowledge menu sheet metal manufacturing and services. Standard gauges of sheet metal chart. Gague are used to specify the thickness of a metal sheet.

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. In the u s the thickness of sheet metal is commonly specified by a traditional non linear measure known as its gauge. 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.

When working with sheet metal the term gauge is often used.
