Aluminum sheet thickness tolerance.
Sheet metal guage tolerances.
An aluminum sheet metal thickness refers to the thickness of an aluminium sheets a flat square or rectangle piece of aluminum material with a thickness of between 0 2mm and 500mm a width of 200mm some are even 50mm and above and more and a length of 16m or less.

The aluminum sheet metal thickness can be divided into four categories.
During the rolling process the rollers bow slightly which results in the sheets being thinner on the edges.
Below you will find the tolerances for plates an sheets according to alloy group.
A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters.
At american metal supply we provide the chart to calculate thickness and sheet tolerance in inches and the weight for various gauges.
Sheet metal is manufactured and delivered from the processing mill rolled to the standard thickness that you specify which is now metric.
The sheet metal does however have a tolerance on the rolling thickness which needs to be taken into account when designing a tight fitting assembly especially as the sheet metal material gets thicker.

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.
