Coil Coated Aluminium Aluminum coil coating is a kind of polyester coating coil. It has the characteristics of high weather resistance, which can effectively improve the anti-ultraviolet ability and prolong the service life of outdoor use. Painted Aluminium Coil Painted aluminium coil is an industrial process used to produce pre-coated aluminum coils. Different types of coatings are available: anodized, painted, liquid or powder coating. This method is used to promote the use of aluminum in most environmental conditions. For this reason, the application of coil coating involves two major industries: architecture and interior design. Painted aluminium coil is the process of applying a protective layer or coating to aluminum coils or sheets. The coating is typically applied using a continuous coil coating process, in which the aluminum is passed through a series of coating stations on a continuous production line. The coating material is applied to the aluminum using a variety of techniques, such as roll coating, spray coating, or electrostatic coating.
