Different Gauges Of Sheet Metal

Kynar aluminum for metal roofing.

Different gauges of sheet metal. Kynar galvalume steel for metal roofing and gutters. 0 7 mm 0 8mm and 1 5 mm. Sheet metal on the other hand is basically metal designed into thin quantities used for metalworking. The customary range gauge of a metal sheet is from a scale of 35 going down to 6.

For example a gage ordinarily used for copper brass and other non ferrous materials may incorrectly be used for steel and vice versa. Even when the non ferrous metal plate and the steel plate are the same ga the thickness is actually different. Steel or sheet metal steel is an alloy made up of different kinds of elements. But iron presents the greatest value compared to other components such as carbon.

The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. Thus a 10 gauge steel sheet which has a thickness of 0 1345 inches will weigh 41 82 0 1345 5 625 pounds per square foot. Click here for more. 16 ga crs is 2 5 pounds per square foot.

The gauge system has long history in metal fabrication. There are several different gauge systems used today with specific gauge designations used for specific metal types. Sheet metal measuring tools. 0 027 or 0 032 for seamless gutters and any other thickness for custom gutters.

You can find the gauge to mm inch conversion for sheet metal by the chart below. History of the gauge system. Unfortunately there is considerable variation in the use of different gages. Because of the varying thicknesses a gauge chart should be used to ensure the metal meets the required dimensions.

It should be noted that aluminum is usually classified by inches rather than gauge as there is no official gauge standard for aluminum. For example in one gauge system 18 gauge steel measures 0 0478 inches thick but 18 gauge aluminum is 0 0403 inches thick. The brown and sharpe gage also known as the american wire gage awg is used for most non ferrous metals such as aluminum and brass. Is different from inches there is no conversion formula.
