Plate Gauge Thickness

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.

Plate gauge thickness.

Gauge or gage sizes are numbers that indicate the thickness of a piece of sheet metal with a higher number referring to a thinner sheet. Because of the varying thicknesses a gauge chart should be used to ensure the metal meets the required dimensions. The progression of thicknesses is clear in column 3 u s. Bwg birmingham wire gauge used to determine wall thickness of pipe in gauge and decimal parts of inch.

Corresponds to the standard steel thickness of 0 0329 inches 0 84mm. Approximate thickness in decimal parts of an inch. History of the gauge system the gauge system has long history in metal fabrication. Awg american wire gauge and circular mils awg diameter mil circular mil diameter in mm and area in mm 2.

For the purpose of securing uniformity the following is established as the only standard gauge for sheet and plate iron and steel in the united states of america namely. For example in one gauge system 18 gauge steel measures 0 0478 inches thick but 18 gauge aluminum is 0 0403 inches thick. The corresponding galvanized steel thickness is 0 0366 inches 0 93mm and the corresponding aluminum thickness is 0 028 inches 0 71mm. 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.

16 ga crs is 2 5 pounds per square foot. Gauge to thickness chart click here for a printable pdf chart gauge. The gauge thicknesses shown in column 2 u s. Approximate thickness in fractions of an inch.
