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.

Imperial sheet metal sizes.

The imperial paper sizes were used to define large sheets of paper and the naming convention was derived from the sheet name and how many times it was folded. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. The corresponding galvanized steel thickness is 0 0366 inches 0 93mm and the corresponding aluminum thickness is 0 028 inches 0 71mm. Class 12 9 1 200 mpa high tensile.

For example royal paper is 508mm x 635mm and when it is folded three times it makes 8 sheets and goes by the name royal octavo which is 253 mm x 158 mm.
