Standard Sheet Metal Gauge Tolerance

The larger the gauge number the thinner the metal.

Standard sheet metal gauge tolerance.

Gauges are neither standard nor metric and the values are independent of those measurement systems. The following sheet metal gauge size reference chart gives the weight and thickness of sheet metal given as a gauge sometimes spelled gage and indicates the standard thickness of sheet metal and wire for most materials as the gauge number increases the material thickness. Use gauge tables in your 3 d sheet metal work flow. The gauge table creates a convenient drop down list so that only valid sheet metal thicknesses may be selected.

Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters. This is known as the manufacturers standard gage for sheet steel. Aluminum sheet thickness tolerances 1100 3003 5052 6061 2024 7075 1100 3003 5052 6061 2024 7075.

As the gauge number increases the material thickness decreases. Monroe nor any of its employees shall be held liable for any improper or incorrect use of the information described and or contained herein and assumes no responsibility for anyone s use of the information. 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. Gauge differs between ferrous iron based metals and nonferrous metals such as aluminum or copper.

Here is another dfm tip. An accurate gauge table helps with modeling speed and provides a degree of self explanation to other cad jockeys who review the model. Sheet metal gauges the below table summarizes sheet metal gauge and tolerances. Contact us to know more about our reference chart in cincinnati louisville.

For other materials such as aluminum and brass the thicknesses will be different. 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. 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.

Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness. At american metal supply we provide the chart to calculate thickness and sheet tolerance in inches and the weight for various gauges.
