Rolling
 
Ingots are transferred from the ingot mill to the hot rolling mill where they are heated to around 600 degrees celcius and passed back and forth up to 28 times through a hot reversing mill.  This turns the ingot into a long aluminium strip approximately 100m long and 18mm thick.
 
The strip is then transferred to the hot continuous rolling mill where it is passed through two more rolling stands to further reduce the thickness to between 2mm and 6mm before being coiled and cooled.
 
Once cooled, the coil is transported to the cold rolling mills where the aluminium’s thickness is again reduced.  The coil passes through each of the two cold rolling mills twice at high speed – with up to 800m of coil passing through the cold rolling mill per minute – where it can be reduced to a thickness of just 0.25mm.  The aluminium is again coiled and transported to finishing.
 
Most aluminium sheet requires a finishing step such as cleaning, coating or slitting.  All products are trimmed to customer specified widths before being dispatched to the customer via road, rail and sea.
