23、 appearance when produced by the manufacture of thecoated sheet. Typically, the coating contains between 8 and 12 % iron, which is the result of a diffusion reaction between the steelsheet and the zinc coating during the coating process. In most applications, this product is intended to be painted.
24、The coating offersexcellent paint adhesion. When the product is exposed to the environment without a paint coating, there is a tendency for thedevelopment of a rust-colored stain on the surface. This is caused by the presence of iron in the coating. This stain may beaesthetically objectionable to so

The aluminum-silicon alloy coatin
26、g provides galvanic corrosion only in marine environments. Because thiscoating does not generally provide galvanic protection, rust staining may be evident at area where the base metal is exposed tothe environment, such as at punch-outs, cut or sheared edges of members, and at scratches.3.2.10 alumi
