Standard 20 gauge steel is .0359 inches thick. Galvanized 20 gauge steel is thicker at .0396 inches and 20 gauge aluminum is thinner at .0320 inches thick. The thickness of a piece of steel is also indicative of its maximum bending capacity.Continue Reading
The higher the gauge of a piece of sheet metal, the lower its thickness. This means that 3-gauge metal is thicker than 20-gauge metal.
Sheet metal is used for a variety of purposes, one of which is brakes on a vehicle. Sheet metal may also be used in construction, such as on the roof of a building. There are also instances of using sheet metal in interior design; it can be used to cover floors or walls.Learn more about Building Materials
Standard sizes for engineered wood "I" beams include flange sizes of 1 3/4, 2 5/16, 2 7/16 and 3 1/2 inches. Depths come in 9 1/2, 11 7/8, 14 and 16 inches, while lengths come in 20 to 48 feet. Lengths of up to 60 feet are custom ordered.Full Answer >
The standard thickness of sheet metal depends on the gauge and the type of metal. For example, 3-gauge steel is 0.2391 inches thick, while a sheet of 3-gauge zinc is 0.006 inches thick.Full Answer >
An ultrasonic thickness gauge is a small, computerized instrument that measures the thickness of material using high frequency sound waves or ultrasound. Placed against one side of the material, its transducer, a small probe, generates an ultrasonic burst that echoes back when hitting the other side of the material.Full Answer >
Calculate sheet metal thickness by using a sheet metal gauge chart. Select the appropriate chart based on the type of sheet metal you have, find the gauge of the sheet metal on the chart and then locate the corresponding thickness on that gauge's row of the chart. For example, a 10-gauge sheet of standard structural steel corresponds to a thickness of 0.1345 inches or 3.416 millimeters.Full Answer >
