Sheet Metal Gauge Thickness In Mm

Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness.

Sheet metal gauge thickness in mm.

For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter. The gauge number 18 holds no relevance to the actual measurements. Sheet metal thickness is denoted by gauge sometimes spelled gage which indicates a standard thickness before processing. Processing may include polishing or the applying of protective plastics which will decrease or increase a sheet s thickness respectively.

This is known as the manufacturers standard. A sheet metal gauge sometimes spelled gage indicates the standard thickness of sheet metal for a specific material. 1 inch 25 4 mm. 1 smacna sheet metal and air conditioning contractors national association recommended gages for circular ducts for heating and general ventilation work.

The corresponding galvanized steel thickness is 0 0366 inches 0 93mm and the corresponding aluminum thickness is 0 028 inches 0 71mm. As the gauge number increases the material thickness decreases. 0 0187 0 452 0 0217 0 55. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.

Sheet metal gauge size chart 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. Corresponds to the standard steel thickness of 0 0329 inches 0 84mm. Sheet metal gauge thickness chart 2019 10 24t01 36 33 00 00 when working with sheet metal the term gauge is often used. Gague are used to specify the thickness of a metal sheet.
