Gauge Sizes Of Sheet Metal

Charts for aluminum steel stainless steel and galvanized steel sheet are presented here with thicknesses ranging from 1 64 to 1 4 inch.

Gauge sizes of sheet metal. 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. 0 7 mm 0 8mm and 1 5 mm. 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. 26 gauge 24 gauge 20 gauge 18 gauge 16 gauge 14 gauge 1 8 and 1 4.

0 027 or 0 032 for seamless gutters and any other thickness for custom gutters. 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. Gauge numbers continue both to thicker and thinner sections but these charts cover the most common ranges.

The gauge number 18 holds no relevance to the actual measurements. 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.
