Common Sheet Metal Thickness

This measurement is for around duct smaller than 12 inches in diameter and a rectangular section no bigger than 8 inches.

Common sheet metal thickness.

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. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. The gauge number 18 holds no relevance to the actual measurements. In most of the world sheet metal thickness is consistently specified in millimeters.

Approximate thickness in decimal parts of an. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter. 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 thin sheet metal is easy to form while still providing great strength.

Anything above that is a metal plate. General information of aluminum sheet thickness. Approximate thickness in fractions of an inch. The thickness of sheet metal starts from 0 5 mm and goes up to 6 mm.

A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters. At a relatively cheap price it makes a great fit for most engineering purposes. There are several different gauge systems used today with specific gauge designations used for specific metal types.
