Gauge Sheet Metal Definition

Gague are used to specify the thickness of a metal sheet.

Gauge sheet metal definition.

Sheet metal gauges the below table summarizes sheet metal gauge and tolerances. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. As the gauge number increases the material thickness decreases. In the u s the thickness of sheet metal is commonly specified by a traditional non linear measure known as its gauge.

Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. The larger the gauge number the thinner the metal. Gauge differs between ferrous iron based metals and nonferrous metals such as aluminum or copper.

The manufacturers standard gage provides the thicknesses for standard steel galvanized steel and stainless steel. Gauge is a dimensionless number sometimes spelled gage and confusingly it works backwards. Usually a bigger number means there s more of something but 18 gauge steel is thinner than 16ga not thicker. Gague ga is a length measurement unit for diameters originating in north america and belongs to the browne sharpe metering system.

When working with sheet metal the term gauge is often used. A sheet metal gauge sometimes spelled gage indicates the standard thickness of sheet metal for a specific material. As the gauge number increases the thickness drops by 10 percent. This is known as the manufacturers standard gage for sheet steel.

Unit of thickness of a metal sheet or wire. 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.
