Sheet Metal Gauge Thickness Fractional

Table 1 below summarizes the most common sheet metal sizes for aluminum standard sheet steel stainless steel and galvanized steel.

Sheet metal gauge thickness fractional.

For other materials such as aluminum and brass the thicknesses will be different.

Now to find the maximum capacity for aluminum simply multiply the thickness of your mild steel by 1 5. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter.

The maximum capacity of a sheet metal brake or shear is based on the total thickness gauge of mild steel at its full length. So a 20 gauge brake has a maximum bending capacity of 036. Inches mm inches mm inches mm inches mm 26. The larger the gauge number the thinner the metal.

This is known as the manufacturers standard gage for sheet steel. As the power to draw thicker wires became available the new gauge numbers had to be assigned. The customary range gauge of a metal sheet is from a scale of 35 going down to 6. The gauge number 18 holds no relevance to the actual measurements.

In most of the world sheet metal thickness is consistently specified in millimeters. Thickness that is more than 6mm or 0 25 inches is called plates. 1 had already been established no. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge.

Gauge to thickness chart. The gauge of sheet metal ranges from 35 gauge to about 6 gauge. Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness. As a registered iso 9001 2015 company rolled steel products state of the art equipment meets virtually any requirement in panel flat quality leveling precision slitting close tolerance sheet blanking strip quality edge conditioning precision shearing and complete cold reducing capabilities.

For example 20 gauge mild steel is 036 thick. Theoretical gauge thickness. 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. In the u s the thickness of sheet metal is commonly specified by a traditional non linear measure known as its gauge.
