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.

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. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness.

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. 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 other materials such as aluminum and brass the thicknesses will be different.

Thus a 10 gauge steel sheet which has a thickness of 0 1345 inches will weigh. Gauge to thickness chart click here for a printable pdf chart gauge.
