Gauge Sheet Metal Definition

Gauge differs between ferrous iron based metals and nonferrous metals such as aluminum or copper.

Gauge sheet metal definition.

The manufacturers standard gage provides the thicknesses for standard steel galvanized steel and stainless steel. A sheet metal gauge sometimes spelled gage indicates the standard thickness of sheet metal for a specific material. When working with sheet metal the term gauge is often used. The larger the gauge number the thinner the metal.

In the u s the thickness of sheet metal is commonly specified by a traditional non linear measure known as its gauge. This is known as the manufacturers standard gage for sheet steel. Usually a bigger number means there s more of something but 18 gauge steel is thinner than 16ga not thicker. 1 for sheet metal a retrogressive scale higher numbers mean lower thickness that starts with 10 gauge representing a thickness of 3 416 millimeters or 0 1345 inches.

Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. Gague ga is a length measurement unit for diameters originating in north america and belongs to the browne sharpe metering system. Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness. As the gauge number increases the thickness drops by 10 percent.

Gauge is a dimensionless number sometimes spelled gage and confusingly it works backwards. 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. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.
