  • Sheet Metal Thickness - Sheet Metal Work, Fabrication ...

    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.
