Common Sheet Metal Thickness

General information of aluminum sheet thickness.

Common sheet metal thickness.

A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. The thickness of sheet metal starts from 0 5 mm and goes up to 6 mm. 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.

At a relatively cheap price it makes a great fit for most engineering purposes. 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. 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. There are several different gauge systems used today with specific gauge designations used for specific metal types. Approximate thickness in fractions of an inch. The manufacturers standard gage provides the thicknesses for standard steel galvanized steel and stainless steel.

Anything above that is a metal plate. 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.
