Gauge sizes of sheet metal. Gauge numbers continue both to thicker and thinner sections but these charts cover the most common ranges. 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. Charts for aluminum steel stainless steel and galvanized steel sheet are presented here with thicknesses ranging from 1 64 to 1 4 inch. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.

Kynar galvalume steel for metal roofing and gutters. 26 gauge 24 gauge 20 gauge 18 gauge 16 gauge 14 gauge 1 8 and 1 4. The gauge number 18 holds no relevance to the actual measurements. 0 7 mm 0 8mm and 1 5 mm.

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. Kynar aluminum for metal roofing. 0 027 or 0 032 for seamless gutters and any other thickness for custom gutters. 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 charts include fractional decimal and metric dimensions for reference.
