How Does Sheet Metal Gauge Work

When figuring out a metal s thickness keep the following facts in mind.

How does sheet metal gauge work. For other materials such as aluminum and brass the thicknesses will be different. A sheet metal gauge sometimes spelled gage indicates the standard thickness of sheet metal for a specific material. Gauges are neither standard nor metric and the values are independent of those measurement systems. M d 24 in x 3 ft aluminum sheet metal.

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. Sheet metal gauge and thickness metal sheet thickness is measured in gauge. In most of the world sheet metal thickness is consistently specified in millimeters. In the u s the thickness of sheet metal is commonly specified by a traditional non linear measure known as its gauge.

After determining what type and shape of metal you need for your project you will need to figure its gauge. You should also know about gauge when discussing sheet metal with your friendly indiana based metal fabricator. When cutting out a circle one or sometimes two cutting tools are rotated about a center point to. The larger the gauge number the thinner the metal.

For pricing and availability. Sheet metal is specified in gauge so rather than design in fractions of an inch you should really be specifying ga on part prints. 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.

The table below provides conversion to inches. This is known as the manufacturers standard gage for sheet steel. Hillman 24 in x 24 in cold rolled steel solid sheet metal. Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness.

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

The higher the numbered gauge a piece of metal is the thicker the piece is in millimeters. Gauge numbers run from 3ga 0 2391 thick up to or should that be down to 38ga 0 0060 thick. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. A metal s gauge refers to its thickness which greatly affects its resistance.

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.
