Different gauges of sheet metal.

The customary range gauge of a metal sheet is from a scale of 35 going down to 6. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. 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.

Galvanized steel sheet metal measuring 30 gauges equals 0 0157 inch but the same gauge standard steel sheet metal measures 0 0120 inch and 30 gauge stainless steel measures 0 0125 inch. But iron presents the greatest value compared to other components such as carbon. 0 7 mm 0 8mm and 1 5 mm. 16 ga crs is 2 5 pounds per square foot.

Unfortunately there is considerable variation in the use of different gages. For 18 ga crs the weight is 2 0 pounds per square foot and for 20 ga crs the weight is 1 5 pounds per square foot. Kynar aluminum for metal roofing. Sheet metal measuring tools.

Sheet metal on the other hand is basically metal designed into thin quantities used for metalworking. Steel or sheet metal steel is an alloy made up of different kinds of elements. Because of the varying thicknesses a gauge chart should be used to ensure the metal meets the required dimensions. 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.

History of the gauge system. There are several different gauge systems used today with specific gauge designations used for specific metal types. It should be noted that aluminum is usually classified by inches rather than gauge as there is no official gauge standard for aluminum. The gauge system has long history in metal fabrication.

Is different from inches there is no conversion formula. For example in one gauge system 18 gauge steel measures 0 0478 inches thick but 18 gauge aluminum is 0 0403 inches thick. 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. Even when the non ferrous metal plate and the steel plate are the same ga the thickness is actually different.
