Upon contact with oxygen, aluminum oxidizes and forms a thin but stable oxide film, which prevents the further penetration of active substances into the thickness of the material. This film is the basic protective barrier to rust. In problem areas, such as joints, bends and cuts, thin aluminum is reinforced with more durable zinc, so products from aluminum zinc are not demanding on the conditions of tool processing.

The aluminum-zinc coating has a significantly increased service life and can withstand temperatures up to 315?C, reflects up to 45% of light energy and practically does not deform when heated.
