Aluminum Sheet Metal Gauge Tolerance

History of the gauge system the gauge system has long history in metal fabrication.

Aluminum sheet metal gauge tolerance.

Metal gauges below you ll find the info you need with our sheet steel stainless steel and aluminum sheet metal charts. The aluminum sheet metal thickness can be divided into four categories. Super thick sheets mm. During the rolling process the rollers bow slightly which results in the sheets being thinner on the edges.

For example in one gauge system 18 gauge steel measures 0 0478 inches thick but 18 gauge aluminum is 0 0403 inches thick. Sheet metal guage tolerances. Because of the varying thicknesses a gauge chart should be used to ensure the metal meets the required dimensions. Processing may include polishing or the applying of protective plastics which will decrease or increase a sheet s thickness respectively.

Use the chart below to convert standard gauge numbers in decimals of an inch for sheet steel aluminum and stainless steel. The tolerances in the table and attachments reflect current manufacturing practices and commercial standards and are not representative of the manufacturer s standard gauge which has no inherent tolerances.
