Steel rolling process flow sheet.
In short cold rolling results in a final metal sheet that is more accurate in terms of dimensions and properties than the one that is obtained from hot rolling process.
The materials commonly rolled are steel copper magnesium aluminum and their alloys.

In sheet metal industrial practice a sheet may be passed through a series of leveling rolls that flex the sheet in opposite directions to flatten it.

Another interesting defect that can occur in flat rolling is alligatoring where the work being rolled actually splits in two during the process.
It is one of the most widely used among all the metal working processes because of its higher productivity and lower cost.
