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.When International Standards that reference this standard permit sheet that is slit to less than 600 mm in width to be considered as sheet, tolerances shall be subject to agreement. a The thickness tolerances for sheet in coil form are the same as for sheet supplied in cut lengths but, in cases where welds areSheet 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.
