Aluminium coils are made up of rolled sheets of aluminium, with a hollow cylinder inside upon which the material is wound to create the interior diameter, as shown in Figure 1. Various industry sectors rely on coils made from aluminium for a myriad of applications, including those for construction, electronics, automotive, healthcare, food, manufacturing, aerospace, and more.
Depending on the requirements for each application, the aluminium coil can be surface treated before fabrication into end products. This is achieved in a continuous, efficient and automated process known as coil coating, which improves the corrosion resistance of the material as well as the aesthetic appeal of the coil material.
