Gauge Sizes Of Sheet Metal

Kynar galvalume steel for metal roofing and gutters.

Gauge sizes of sheet metal.

A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters. 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.

Charts for aluminum steel stainless steel and galvanized steel sheet are presented here with thicknesses ranging from 1 64 to 1 4 inch. The following sheet metal gauge size reference chart gives the weight and thickness of sheet metal given as a gauge sometimes spelled gage and indicates the standard thickness of sheet metal and wire for most materials as the gauge number increases the material thickness decreases.

For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter. 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. Kynar aluminum for metal roofing. 0 027 or 0 032 for seamless gutters and any other thickness for custom gutters.

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.
