Sheet metal measuring tools.

Different gauges of sheet metal.

Is different from inches there is no conversion formula. The manufacturers standard gage provides the thicknesses for standard steel galvanized steel and stainless steel. 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.

Unfortunately there is considerable variation in the use of different gages. Even when the non ferrous metal plate and the steel plate are the same ga the thickness is actually different.

16 ga crs is 2 5 pounds per square foot. Kynar galvalume steel for metal roofing and gutters. There are several different gauge systems used today with specific gauge designations used for specific metal types. The gauge system has long history in metal fabrication.

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. 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. You can find the gauge to mm inch conversion for sheet metal by the chart below. But iron presents the greatest value compared to other components such as carbon.

History of the gauge system. 0 027 or 0 032 for seamless gutters and any other thickness for custom gutters. Steel or sheet metal steel is an alloy made up of different kinds of elements. 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. Sheet metal on the other hand is basically metal designed into thin quantities used for metalworking. Kynar aluminum for metal roofing. 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.
