Gauge Sizes Of Sheet Metal

Gauge numbers continue both to thicker and thinner sections but these charts cover the most common ranges.

Gauge sizes of sheet metal.

Kynar aluminum for metal roofing. A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters. The charts include fractional decimal and metric dimensions for reference. 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.

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. Charts for aluminum steel stainless steel and galvanized steel sheet are presented here with thicknesses ranging from 1 64 to 1 4 inch. The gauge number 18 holds no relevance to the actual measurements. 0 027 or 0 032 for seamless gutters and any other thickness for custom gutters.

Kynar galvalume steel for metal roofing and gutters. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter. 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.

0 7 mm 0 8mm and 1 5 mm.
