Aluminium coil manufacturers source aluminium slabs for producing aluminium coils. The ends of these slabs are sawn off and scalped before beginning the coiling process. Given below are the steps in manufacturing aluminium coil:
Step 1 – The scalped slab is placed inside the preheating furnace to be preheated and made ready for the hot rolling process.
Step 2 – The heated slab is put through the hot rolling machine and hot rolled back and forth several times to turn them into sheets with a certain thickness
Step 3 – The hot rolled aluminium sheet is then sent to cold rolling.
Step 4 – The cold rolled steel is then sent to the annealing furnace to adjust the properties of the coil to match the customer requirements.
