Gauge Sheet Metal Definition

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

Gauge sheet metal definition.

Usually a bigger number means there s more of something but 18 gauge steel is thinner than 16ga not thicker. Sheet metal is specified in gauge so rather than design in fractions of an inch you should really be specifying ga on part prints. As the gauge number increases the material thickness decreases. Unit of thickness of a metal sheet or wire.

Gague are used to specify the thickness of a metal sheet. This is known as the manufacturers standard gage for sheet steel. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. 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.

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. Sheet metal gauges the below table summarizes sheet metal gauge and tolerances. 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 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. The manufacturers standard gage provides the thicknesses for standard steel galvanized steel and stainless steel. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge.

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