Aluminum Sheet Metal Gauge Tolerance

Processing may include polishing or the applying of protective plastics which will decrease or increase a sheet s thickness respectively.

Aluminum sheet metal gauge tolerance.

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. For example in one gauge system 18 gauge steel measures 0 0478 inches thick but 18 gauge aluminum is 0 0403 inches thick. 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. Sheet metal guage tolerances. Click here for a gauge to mm conversion chart. Super thick sheets mm.
