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.
Sheet steel gauges in mm.
For different materials of steel the same gauge will also correspond to different mm.
Typically the even number gauges are used more frequently.

The table below shows the actual thickness of sheet steel in millimetres and inches compared to gauge size.
The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.
