Common Sheet Metal Thickness

There are several different gauge systems used today with specific gauge designations used for specific metal types.

Common sheet metal thickness.

Approximate thickness in decimal parts of an. A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters. In most of the world sheet metal thickness is consistently specified in millimeters. This measurement is for around duct smaller than 12 inches in diameter and a rectangular section no bigger than 8 inches.

The thickness of sheet metal starts from 0 5 mm and goes up to 6 mm. The thin sheet metal is easy to form while still providing great strength. The manufacturers standard gage provides the thicknesses for standard steel galvanized steel and stainless steel. General information of aluminum sheet thickness.

An aluminum sheet metal thickness refers to the thickness of an aluminium sheets a flat square or rectangle piece of aluminum material with a thickness of between 0 2mm and 500mm a width of 200mm some are even 50mm and above and more and a length of 16m or less. The gauge number 18 holds no relevance to the actual measurements. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter. Approximate thickness in fractions of an inch.

The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. 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. A sheet metal gauge sometimes spelled gage indicates the standard thickness of sheet.
