Gauge System Sheet Metal

The gauge of a sheet of metal is a reference to how thick it is.

Gauge system sheet metal.

A sheet metal gauge sometimes spelled gage indicates the standard thickness of sheet metal for a specific material. The table below provides conversion to inches. Metal sheet thickness is measured in gauge. Depending on the gauge system used to classify the material and the composition of the material two sheets of metal with the same thickness may have different gauges.

The following sheet metal gauge size reference chart gives the weight and thickness of sheet metal given as a gauge sometimes spelled gage and indicates the standard thickness of sheet metal and wire for most materials as the gauge number increases the material thickness decreases. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. Metal objects including wire sheet metal tubing and hypodermic needles are categorized by their gauges. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.

In most of the world sheet metal thickness is consistently specified in millimeters. When working with sheet metal it is common for the term gauge to be used someone unfamiliar with the gauge system may not understand what is meant by 18 gauge steel for example. 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. If you want to find out what gauge your sheet metal is measure its thickness using a regular tape measure.

As the gauge number increases the material thickness decreases. The larger the gauge number the thinner the metal. The higher the numbered gauge a piece of metal is the thicker the piece is in millimeters. 0 0125 0 0160 0 0125 0 0100 0 0120 29.

Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness. 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. The decimal system of indicating gage sizes has been. In the u s the thickness of sheet metal is commonly specified by a traditional non linear measure known as its gauge.

This is known as the manufacturers standard. Gage standard us gage galvanized steel stainless steel aluminum sheet strip tubing zinc sheet.
