Steel Sheet Metal Gauge Thickness

In the u s the thickness of sheet metal is commonly specified by a traditional non linear measure known as its gauge.
Steel sheet metal gauge thickness. For other materials such as aluminum and brass the thicknesses will be different. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. In most of the world sheet metal thickness is consistently specified in millimeters. A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters.
Thus a 10 gauge steel sheet which has a thickness of 0 1345 inches will weigh. Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter.
The larger the gauge number the thinner the metal. Gauge to thickness chart gauge stainless galvanized sheet steel aluminum fraction inches mm inches mm inches mm inches mm 30 0 0125 0 33 0 0157 0 40 0 0120 0 30 0 0100 0 25.
