In Sheet Metal Work The Device Used To Measure The Sheet Thickness Is

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

In sheet metal work the device used to measure the sheet thickness is.

The higher the numbered gauge a piece of metal is the thicker the piece is in millimeters. Sheet gauges start at 010 and go up to 170 or 7 gauge the thickness for plate sizes can be from 188 and up. The gauge of a sheet of metal is a reference to how thick it is. If you want to find out what gauge your sheet metal is measure its thickness using a regular tape measure.

Sheet metal measuring tool. Spi 36 steel wire and sheet metal gage use with uncoated sheet and plate iron and steel. Checking the specification of materials that have been delivered measurement of in situ materials through coatings if required measuring the remaining wall thickness due to corrosion. Then using a sheet metal gauge chart you can match that thickness up with the appropriate numbered gauge of your product.

You should also know about gauge when discussing sheet metal with your friendly indiana based metal fabricator. 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 positector utg metal thickness tester from defelsko is an ultrasonic thickness gauge which can be used for a number of applications such as. Pec tools 36 steel wire and sheet metal gage use with uncoated sheet and plate iron and steel msc.

Micrometer aluminum sheet thickness is commonly specified using of an inch. Metal sheet thickness is measured in gauge. A gauge is a traditional non linear measurement. The thinnest acceptable sheet metal for ductwork used in a single dwelling is 28 gage or 0 013 and 0 018 inches for galvanized and aluminum respectively.

As metal sheets move down the conveyor laser displacement sensors measure the sheets on a very precise scale to ensure they are the correct thickness. Gauge numbers run from 3ga 0 2391 thick up to or should that be down to 38ga 0 0060 thick. The most commonly used sheet metal sizes range from 30 gauge thinner to 7 gauge thicker. Each line on the barrel of a n represents 0 025 when measuring the thickness of sheet metal.

Sheet metal is specified in gauge so rather than design in fractions of an inch you should really be specifying ga on part prints. In this sheet metal stamping application it is important that the frame brackets and other metal components are identical and that the die is not damaged to prevent down time and costly repairs. A metal s gauge refers to its thickness which greatly affects its resistance. The table below provides conversion to inches.

Automotive metal stamping requires a specific thickness to ensure the parts are equal and to ensure the die is not damaged during this process. 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.
