Aluminum sheet metal gauge tolerance.
Sheet metal gauges the below table summarizes sheet metal gauge and tolerances.
Processing may include polishing or the applying of protective plastics which will decrease or increase a sheet s thickness respectively.
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.
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.
Metal gauges below you ll find the info you need with our sheet steel stainless steel and aluminum sheet metal charts.
Because of the varying thicknesses a gauge chart should be used to ensure the metal meets the required dimensions.
Sheet metal thickness is denoted by gauge sometimes spelled gage which indicates a standard thickness before processing.
The aluminum sheet metal thickness can be divided into four categories.
History of the gauge system the gauge system has long history in metal fabrication.
