Standard Sheet Steel Thickness Mm

A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters.

Standard sheet steel thickness mm.

A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters. Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness. Our suppliers have provided the material data above with the nominal thicknesses based on industry standards. Thicknesses can vary significantly.

Lastly a standard exists for zinc in which a higher gauge number indicates a thicker sheet. Sheet metal gauge thickness chart 2019 10 24t01 36 33 00 00 when working with sheet metal the term gauge is often used. A sheet metal gauge sometimes spelled gage indicates the standard thickness of sheet metal for a specific material. As the gauge number increases the material thickness decreases.

The sheet metal does however have a tolerance on the rolling thickness which needs to be taken into account when designing a tight fitting assembly especially as the sheet metal material gets thicker. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter. Extremely thin sheets are considered foil or leaf and pieces thicker than 6 mm 0 25 in are considered. These will vary from british gauges with some exceptions.

The chart below can be used to determine the equivalent sheet thickness in inches or millimeters for a gauge number from the selected gauge size standard. Sheet metal is metal formed by an industrial process into thin flat pieces. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter. Sheet metal is manufactured and delivered from the processing mill rolled to the standard thickness that you specify which is now metric.

The gauges shown above are based on american stainless steel sheet steel manufacturers gauge thickness. Gauges are neither standard nor metric and the values are independent of those measurement systems.
