Steel Sheet Metal Gauge Thickness

The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.

Steel sheet metal gauge thickness.

Thus a 10 gauge steel sheet which has a thickness of 0 1345 inches will weigh. In the u s the thickness of sheet metal is commonly specified by a traditional non linear measure known as its gauge. 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. The larger the gauge number the thinner the metal.

Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. For other materials such as aluminum and brass the thicknesses will be different. Sheet metal gauge size chart 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. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter.

Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness. This is known as the manufacturers standard gage for sheet steel.
