Plate Gauge Thickness

Is different from inches there is no conversion formula.

Plate gauge thickness.

Weight per square foot. Because of the varying thicknesses a gauge chart should be used to ensure the metal meets the required dimensions. Approximate thickness in millimeters. Approximate thickness in decimal parts of an inch.

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. Bwg birmingham wire gauge used to determine wall thickness of pipe in gauge and decimal parts of inch. Gauge to thickness chart gauge stainless galvanized sheet steel aluminum fraction inches mm inches mm inches mm inches mm 30 0 0125 0 33 0 0157 0 40 0 0120 0 30 0 0100 0 25. 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.

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. 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. 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. This is known as the manufacturers standard gage for sheet steel.

The gauge thicknesses shown in column 2 u s. Awg american wire gauge and circular mils awg diameter mil circular mil diameter in mm and area in mm 2. The progression of thicknesses is clear in column 3 u s. For other materials such as aluminum and brass the thicknesses will be different.

Standard for sheet and plate iron and steel 64ths inch delta. 16 ga crs is 2 5 pounds per square foot. It should be noted that when the non ferrous metal plate and the steel plate are both at a certain ga. Approximate thickness in fractions of an inch.

History of the gauge system the gauge system has long history in metal fabrication. For example in one gauge system 18 gauge steel measures 0 0478 inches thick but 18 gauge aluminum is 0 0403 inches thick. Even when the non ferrous metal plate and the steel plate are the same ga the thickness is actually different.
