Painted aluminum coils are typically made from high-quality aluminum alloy, and coated with a layer of paint and is rolled into a coil form, which provides strength and flexibility. The same as painted aluminum sheet, they are produced by painting process, include methods like coil coating, where the paint is applied in a continuous process before the aluminum coil is cut into sheets or used directly.

Structure of Painted Aluminium Coil:
Process of Coil Coating
Coil coating is a continuous, automated process for coating metal before fabrication into end products. The steel or aluminum substrate is delivered in coil form from the rolling mills. The metal coil is positioned at the beginning of the coating line, and in one continuous process, the coil is unwound, pre-cleaned, pre-treated, pre-primed, and prepainted before being recoiled on the other end and packaged for shipment.
