Coating of aluminum profiles, involves polishing aluminum profile using sandpaper, performing extrusion process on aluminum profile, and forming pores on surface of aluminum profile for perfect adhesion of applied coating
摘要
<p>The process involves polishing an aluminum profile, which has not gone through any surface treatment, and using sandpaper to remove impurities adhering on the surface of the aluminum profile. The aluminum profile then goes through an extrusion process. Pores are then formed on the surface of the aluminum profile for perfect adhesion of coating applied on the surface of the aluminum profile.</p>
