Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness.
Steel sheet metal gauge thickness.
A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters.
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.
In the u s the thickness of sheet metal is commonly specified by a traditional non linear measure known as its gauge.

For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter.
The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.
The larger the gauge number the thinner the metal.
Thus a 10 gauge steel sheet which has a thickness of 0 1345 inches will weigh.
Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge.
