Steel sheet metal gauge thickness tolerance.

Gauge differs between ferrous iron based metals and nonferrous metals such as aluminum or copper. During the rolling process the rollers bow slightly which results in the sheets being thinner on the edges. Hr hot rolled cr cold rolled sheet metal gage guage size chart carbon steel sheets. Sheet metal guage tolerances.

In the u s the thickness of sheet metal is commonly specified by a traditional non linear measure known as its gauge. The tolerances in the table and attachments reflect current manufacturing practices and commercial standards and are not representative of the manufacturer s standard gauge which has no inherent tolerances. 1000 mm wide sheet metal. 1250 mm wide sheet metal.

At american metal supply we provide the chart to calculate thickness and sheet tolerance in inches and the weight for various gauges. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. Thickness tolerance in mm or for given width in mm. The larger the gauge number the thinner the metal.

The following charts give typical astm and ansi steel sheet mechanical tolerance ranges. Gauges are neither standard nor metric and the values are independent of those measurement systems.
