Standard Steel Sheet Metal Gauges

For the purpose of securing uniformity the following is established as the only standard gauge for sheet and plate iron and steel in the united states of america namely.

Standard steel sheet metal gauges.

For other materials such as aluminum and brass the thicknesses will be different. Standard gauge for sheet and plate iron and steel. The larger the gauge number the thinner the metal. Standard gauge for sheet and plate iron and steel.

Standard gauges of sheet metal chart. Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness. Related product s the thickness of sheet metal is commonly specified by a traditional non linear measure known as its gauge. Gauges are neither standard nor metric and the values are independent of those measurement systems.

Gauge differs between ferrous iron based metals and nonferrous metals such as aluminum or copper. In the u s the thickness of sheet metal is commonly specified by a traditional non linear measure known as its gauge. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. The brown and sharpe gage also known as the american wire gage awg is used for most non ferrous metals such as aluminum and brass.

A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter.
