Steel Sheet Metal Gauge Thickness

A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters.

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

In most of the world sheet metal thickness is consistently specified in 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. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.

Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. Thus a 10 gauge steel sheet which has a thickness of 0 1345 inches will weigh.
