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

A sheet metal gauge sometimes spelled gage indicates the standard thickness of sheet metal for a specific material. For a weight bearing floor use 14 or 12 gauge steel. Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness. Automotive sheet metal once ran in the range of 18 gauge which was 48 thousandths of an inch thick actually 0 0478 inch.

Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. In the u s the thickness of sheet metal is commonly specified by a traditional non linear measure known as its gauge. In most of the world sheet metal thickness is consistently specified in millimeters. Many racing organizations will specify the minimum acceptable gauge for sheet metal in critical applications such as firewalls and protective enclosures.
