Gauge System Sheet Metal

To help this blog will explain the gauge system and features a sheet metal gauge chart.

Gauge system sheet metal.

Sheet metal gauges are not universally standardized. As the gauge number increases the material thickness decreases. The higher the numbered gauge a piece of metal is the thicker the piece is in millimeters. 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.

The larger the gauge number the thinner the metal. This is known as the manufacturers standard. In the u s the thickness of sheet metal is commonly specified by a traditional non linear measure known as its gauge. 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.

Metal objects including wire sheet metal tubing and hypodermic needles are categorized by their gauges.

The gauge of a sheet of metal is a reference to how thick it is. The table below provides conversion to inches.

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. A sheet metal gauge sometimes spelled gage indicates the standard thickness of sheet metal for a specific material. Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness. If you want to find out what gauge your sheet metal is measure its thickness using a regular tape measure.

The decimal system of indicating gage sizes has been. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. Metal sheet thickness is measured in 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.
