A sheet metal gauge sometimes spelled gage indicates the standard thickness of sheet metal for a specific material. Typically the even number gauges are used more frequently. The story of gauge. The gauge number 18 holds no relevance to the actual measurements.

The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. 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. Standard steel mm non ferrous aluminum mm galvanized steel mm 000000. This is known as the manufacturers standard.

This chart covers the common and uncommon sheet metal sizes for steel aluminum and galvanized steel.
