2. Resistance to Corrosion Unlike steel or wood, aluminum has excellent resistance to corrosion.

Aluminum roll window profile

The surface of the aluminium profile is lightly drawn with a smooth hard object, which can leave a white mark on the surface of the profile. If it can be wiped off by hand, it means that the anodised film is not wiped off. If it cannot be rubbed by hand, the anodised film has been wiped off, indicating that the anodised film is poor in firmness and too thin, and the surface quality is poor. The average film thickness of the anodised aluminium profile for doors and windows needs to be at least 15um.
