It s also important when working with sheet metal that you factor in finish tolerances.
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.
During the rolling process the rollers bow slightly which results in the sheets being thinner on the edges.
Because of the varying thicknesses a gauge chart should be used to ensure the metal meets the required dimensions.

History of the gauge system the gauge system has long history in metal fabrication.
The aluminum sheet metal thickness can be divided into four categories.
Sheet metal guage tolerances.
Use the chart below to convert standard gauge numbers in decimals of an inch for sheet steel aluminum and stainless steel.
For example in one gauge system 18 gauge steel measures 0 0478 inches thick but 18 gauge aluminum is 0 0403 inches thick.
