20 Gauge Thickness Sheet Metal

In the u s the thickness of sheet metal is commonly specified by a traditional non linear measure known as its gauge.

20 gauge thickness sheet metal. Gague are used to specify the thickness of a metal sheet. Kynar aluminum for metal roofing. 26 gauge 24 gauge 20 gauge 18 gauge 16 gauge 14 gauge 1 8 and 1 4. 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 larger the gauge number the thinner the metal. Galvanized 20 gauge steel is thicker at 0396 inches and 20 gauge aluminum is thinner at 0320 inches thick. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter. The thickness of a piece of steel is also indicative of its maximum bending capacity.

Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness. Sheet metal gauge size chart 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. In most of the world sheet metal thickness is consistently specified in millimeters.

This is known as the manufacturers standard. Standard 20 gauge steel is 0359 inches thick. Approximate thickness in fractions of an inch. Kynar galvalume steel for metal roofing and gutters.

Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. 0 7 mm 0 8mm and 1 5 mm. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. 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.

As the gauge number increases the material thickness decreases. A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters. Approximate thickness in decimal parts of an inch.
