Gauge Definition Sheet Metal

Gauges are neither standard nor metric and the values are independent of those measurement systems.

Gauge definition sheet metal. Gague ga is a length measurement unit for diameters originating in north america and belongs to the browne sharpe metering system. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. Unit of thickness of a metal sheet or wire. In the u s the thickness of sheet metal is commonly specified by a traditional non linear measure known as its gauge.

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. When working with sheet metal the term gauge is often used. Gauges are used to specify the thickness of a sheet metal.

The manufacturers standard gage provides the thicknesses for standard steel galvanized steel and stainless steel. This is known as the manufacturers standard gage for sheet steel. As the gauge number increases the material thickness decreases. The larger the gauge number the thinner the metal.

Gague are used to specify the thickness of a metal sheet. A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters. Gauge is a dimensionless number sometimes spelled gage and confusingly it works backwards. Sheet metal is specified in gauge so rather than design in fractions of an inch you should really be specifying ga on part prints.

A sheet metal gauge sometimes spelled gage indicates the standard thickness of sheet metal for a specific material. Gauge differs between ferrous iron based metals and nonferrous metals such as aluminum or copper. As the gauge number increases the thickness drops by 10 percent. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge.

How to use gauge in a sentence. Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness.
