22、roduced by the manufacture of the coated sheet. Typically, thecoating contains between 8 and 12 % iron, which is the result of a diffusion reaction between the steel sheet and the zinc coatingduring the coating process. In most applications, this product is intended to be painted. The coating offers
23、 excellent paint adhesion.When the product is exposed to the environment without a paint coating, there is a tendency for the development of a rust-coloredstain on the surface. This is caused by the presence of iron in the coating. This stain may be aesthetically objectionable to someusers of cold f

Thealuminum-silicon alloy coating provides galvani

Because this coating does not generallyprovide galvanic protection, rust staining may be evident at area where the base metal is exposed to the environment, such as atpunch-outs, cut or sheared edges of members, and at scratches.3.2.10 aluminum coating type 2
