What is aluminum coil?
Aluminum coil is the rolled product that has been calendered by a finishing mill but has not been processed by a leveling flying shear. It is the raw material of aluminum strip and aluminum sheet. The slitting equipment can cut aluminum coil into aluminum strip, and the flattening equipment can make aluminum coil into aluminum sheet.
