21、e manufacture ofthe coated sheet. Typically, the coating contains between 8 and12 % iron, which is the result of a diffusion reaction betweenthe steel sheet and the zinc coating during the coating process.In most applications, this product is intended to be painted. Thecoating offers excellent paint
22、 adhesion. When the product isexposed to the environment without a paint coating, there is atendency for the development of a rust-colored stain on thesurface. This is caused by the presence of iron in the coating.This stain may be aesthetically objectionable to some users ofcold formed framing memb

Because this coating does not generally provide gal-vanic protection, rust staining may be evident at area where thebase metal is exposed to the environment, such as at punch-outs, cut or sheared edges of members, and at scratches.3.2.10 aluminum coating type 2, na coating of co
