How does sheet metal gauge work.

The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. Gauges are used to specify the thickness of a sheet metal. Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness. This is known as the manufacturers standard gage for sheet steel.

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. A metal s gauge refers to its thickness which greatly affects its resistance. In the u s the thickness of sheet metal is commonly specified by a traditional non linear measure known as its gauge. Wire conductor sizes are also measured in gauge and are equivalent to the non ferrous thicknesses listed below but we have an article specific to wire gauge.

When cutting out a circle one or sometimes two cutting tools are rotated about a center point to. The gauge of a sheet of metal is a reference to how thick it is. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. The larger the gauge number the thinner the metal.

Sheet metal gauge and thickness metal sheet thickness is measured in gauge. The table below provides conversion to inches. A sheet metal gauge sometimes spelled gage indicates the standard thickness of sheet metal for a specific material. The higher the numbered gauge a piece of metal is the thicker the piece is in millimeters.

A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters. Sheet gauges start at 010 and go up to 170 or 7 gauge. When figuring out a metal s thickness keep the following facts in mind. M d 24 in x 3 ft aluminum sheet metal.

As the gauge number increases the material thickness decreases. Gauge numbers run from 3ga 0 2391 thick up to or should that be down to 38ga 0 0060 thick. You should also know about gauge when discussing sheet metal with your friendly indiana based metal fabricator. That way if we suggest something like switching from 14 to 16ga to tighten a bend radius or save weight you ll know what we mean.

If you want to find out what gauge your sheet metal is measure its thickness using a regular tape measure. When drilling or punching a hole in sheet metal you more or less cut out the entire hole at once. Thus a 10 gauge steel sheet which has a. In most of the world sheet metal thickness is consistently specified in millimeters.

For other materials such as aluminum and brass the thicknesses will be different. Sheet metal is specified in gauge so rather than design in fractions of an inch you should really be specifying ga on part prints.
