Gauge Sheet Metal Definition

A sheet metal gauge sometimes spelled gage indicates the standard thickness of sheet metal for a specific material.

Gauge sheet metal definition.

Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness. Gauge differs between ferrous iron based metals and nonferrous metals such as aluminum or copper. 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. As the gauge number increases the thickness drops by 10 percent.

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. Gague are used to specify the thickness of a metal sheet. As the gauge number increases the material thickness decreases.

The manufacturers standard gage provides the thicknesses for standard steel galvanized steel and stainless steel. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. 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.

Gauge is a dimensionless number sometimes spelled gage and confusingly it works backwards. This is known as the manufacturers standard gage for sheet steel. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. Sheet metal gauges the below table summarizes sheet metal gauge and tolerances.

Unit of thickness of a metal sheet or wire. Sheet metal is specified in gauge so rather than design in fractions of an inch you should really be specifying ga on part prints.
