20、loy-coating is normallydull gray in appearance when produced by the 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 pr
21、oduct is intended to be painted. Thecoating offers excellent paint 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 ae
22、sthetically objectionable to some users ofcold formed framing members.3.2.9 aluminum coating type 1, na coating of aluminumand silicon alloy on steel sheet.3.2.9.1 DiscussionAluminum-coated steel sheet type 1provides protection from corrosion primarily through thebarrier action of the coating. The a
23、luminum-silicon alloycoating provides galvanic corrosion only in marine environ-ments. 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,
24、 and at scratches.3.2.10 aluminum coating type 2, na coating of commer-cially pure aluminum on steel sheet.3.2.10.1 DiscussionAluminum-coated steel sheet type 2provides protection from corrosion primarily through thebarrier action of the coating. The aluminum coating providesgalvanic corrosion only
25、in marine environments. Because thiscoating does not generally provide galvanic protection, ruststaining may be evident at areas where the base metal isexposed to the environment such as at punch-outs, cut orsheared edges of members, and at scratches.3.3 Suffxes: H, adjhigh ductility.L, adjlow ducti
