Gages Of Sheet Metal Sizes

The thickness of sheet metal is commonly specified by a traditional non linear measure known as its gauge.

Gages of sheet metal sizes.

The gauge number 18 holds no relevance to the actual measurements. Metal gauges below you ll find the info you need with our sheet steel stainless steel and aluminum sheet metal charts. Use the chart below to convert standard gauge numbers in decimals of an inch for sheet steel aluminum and stainless steel. Please note that astm states in specification astm a480 10a the use of gage number is discouraged as being an archaic term of limited usefulness not having general agreement on meaning.

A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters. Originally used in the fields of medicine and jewellery the larger the number the smaller the diameter and now it is also used to indicate the thickness. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. When working with sheet metal the term gauge is often used.

Gague are used to specify the thickness of a metal sheet. 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.
