Metric Sheet Metal Thickness

We offer three types of metric low carbon steel sheets.

Metric sheet metal thickness.

Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness. A sheet metal gauge sometimes spelled gage indicates the standard thickness of sheet metal for a specific material. A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters. Si metric conversion tables sheet metal gauge to metric mm equivalent thickness.

For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter. Cold rolled steel sheets dc01 electro galvanized steel sheets dc01 ze and hot dip galvanized steel sheets dx51d. Gague ga is a length measurement unit for diameters originating in north america and belongs to the browne sharpe metering system. As the gauge number increases the material thickness decreases.

Sheet metal is manufactured and delivered from the processing mill rolled to the standard thickness that you specify which is now metric. Cold rolled carbon steel sheet metal is used in automotive panels trailer siding roofing and fuel tanks. 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.
