Steel Measurement Sheet

A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters.

Steel measurement sheet.

Sheet metal is specified in gauge so rather than design in fractions of an inch you should really be specifying ga on part prints. Weights of various metals in pounds per cubic foot. Gauge is a dimensionless number sometimes spelled gage and confusingly it works backwards. Gague are used to specify the thickness of a metal sheet.

Gague ga is a length measurement unit for diameters originating in north america and belongs to the browne sharpe metering system. Steel sheets and plates are typical stocked in 36 48 and 60 widths and 96 120 and 144 lengths. Step 1 use a tape measure to find the thickness of your sheet metal piece. Each diameter measured by distance across flats.

Standard practice for using hand micrometers to measure the thickness of uncoated steel sheet and nonmetallic and metallic coated steel sheet a1087 a1087m 16 standard practice for using hand calipers to measure the width of steel sheet. Usually a bigger number means there s more of something but 18 gauge steel is thinner than 16ga not thicker. Example weight of steel plate the weight of a 1 inch thick 36 3 ft x 96 8 ft steel plate with weight 40 8 lb ft2 from table above can be calculated as w 40 8 lb ft2 3 ft 8 ft. Sheet metal guage tool sheet thickness gauge stainless steel welding gage plated size inspection tool pack of 2 wire guage measurement tool 4 6 out of 5 stars 58 6 99 6.

It should be noted that aluminum is usually classified by inches rather than gauge as there is no official gauge standard for aluminum. Sheet thickness x width x length x 2904 lbs. X 2223 lbs. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.

Originally used in the fields of medicine and jewellery the larger the number the smaller the diameter and now it is also used to indicate the thickness. If you want to find out what gauge your sheet metal is measure its thickness using a regular tape measure. The manufacturers standard gage provides the thicknesses for standard steel galvanized steel and stainless steel. Per inch of width sheet circle diameter x diameter x thickness x 228 lbs.

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. Each plate thickness x width x length x 2836 lbs. Then using a sheet metal gauge chart you can match that thickness up with the appropriate numbered gauge of your product.
