Standard sheet metal gauge tolerance.

Use gauge tables in your 3 d sheet metal work flow. Sheet metal guage tolerances during the rolling process the rollers bow slightly which results in the sheets being thinner on the edges. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. The larger the gauge number the thinner the metal.

An accurate gauge table helps with modeling speed and provides a degree of self explanation to other cad jockeys who review the model. Gauge differs between ferrous iron based metals and nonferrous metals such as aluminum or copper. The gauge table creates a convenient drop down list so that only valid sheet metal thicknesses may be selected. Contact us to know more about our reference chart in cincinnati louisville.

At american metal supply we provide the chart to calculate thickness and sheet tolerance in inches and the weight for various gauges. Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness. As the gauge number increases the material thickness decreases. This is known as the manufacturers standard gage for sheet steel.

Gauges are neither standard nor metric and the values are independent of those measurement systems. Haomei common used aluminum sheet thickness 0 3mm 0 5mm 0 8mm 1mm 1 2mm 1 5mm 2mm 2 5mm 3mm 4mm 5mm and above. A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters. Sheet metal gauges the below table summarizes sheet metal gauge and tolerances.

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. Sheet metal knowledge menu sheet metal manufacturing and services. Here is another dfm tip. Conversion data chart standard gauges chart gauge tolerance chart useful data page.

For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter. A aluminium sheets metal gauge sometimes spelled gage indicates the standard thickness of sheet metal for a specific material.
