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.
Gauge sizes of sheet metal.
The charts include fractional decimal and metric dimensions for reference.
0 7 mm 0 8mm and 1 5 mm.
Gauge numbers continue both to thicker and thinner sections but these charts cover the most common ranges.
A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters.
Charts for aluminum steel stainless steel and galvanized steel sheet are presented here with thicknesses ranging from 1 64 to 1 4 inch.
If the plain metal sheet is glued to a solid substrate such as steel heavy plywood or particle board then 20 gauge 0 040 or 1 00 mm stainless steel is sufficient.
The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.
For an identical application in brass alloys which are softer materials we recommend to specify nothing less than 18 or 16 gauge 0 050 or 0 060 1 20 mm or 1 50 mm.
For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter.
