The most effective way for cleaning is to spray water onto the surface of a plain aluminum coil repeatedly until it gets completely clean. Used water can be recycled and reused. The cleaning step erases impurities on the coil surface and improves its sticking effect to paints. Coating consists of two smaller steps: base coating and facial coating. The clean coil surface or surfaces (up to your needs) get coated with a layer of paint (base paint) by the first roller coating machine and then another paint layer (facial paint).

Usually the temperature is between 200 and 300 centigrade.
