Ss Sheet Metal Gage Thickness

Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness.

Ss sheet metal gage thickness. Gauge and weight chart for sheet steel galvanized steel stainless steel aluminum and strip tubing. Wire gauge is a measure for the size of a wire either in diameter or in cross sectional area. The larger the gauge number the thinner the metal. Sheet metal guage tolerances during the rolling process the rollers bow slightly which results in the sheets being thinner on the edges.

As the gauge number increases the material thickness decreases. The tolerances in the table and attachments reflect current manufacturing practices and commercial standards and are not representative of the manufacturer s standard gauge which has no inherent tolerances. This is known as the manufacturers standard gage for sheet steel. Gauge differs between ferrous iron based metals and nonferrous metals such as aluminum or copper.

In the u s the thickness of sheet metal is commonly specified by a traditional non linear measure known as its gauge. Garfield avenue los angeles ca 90040.

For full table with stainless steel aluminum strip and tubing rotate the screen.

A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters. For other materials such as aluminum and brass the thicknesses will be different. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. The gauge number 18 holds no relevance to the actual measurements.

Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter. 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.
