Aluminum Sheet Metal Gauge Metric

Typically the even number gauges are used more frequently.

Aluminum sheet metal gauge metric.

This chart covers the common and uncommon sheet metal sizes for steel aluminum and galvanized steel. For other materials such as aluminum and brass the thicknesses will be different. When working with sheet metal the term gauge is often used. For example in one gauge system 18 gauge steel measures 0 0478 inches thick but 18 gauge aluminum is 0 0403 inches thick.

Gague ga is a length measurement unit for diameters originating in north america and belongs to the browne sharpe metering system. The table below shows the actual thickness of sheet steel in millimetres and inches compared to gauge size. Gague are used to specify the thickness of a metal sheet. As the gauge number increases the material thickness decreases.

This is known as the manufacturers standard gage for sheet steel. There are several different gauge systems used today with specific gauge designations used for specific metal types. The thickness of sheet metals is specified by gauge. For a more comprehensive gauge chart you can check out our sheet metal gauge chart here.

The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness. These dimensions vary slightly between different materials such as stainless steel and aluminium but should be accurate enough for most everyday purposes.
