Terminology3.1 DefinitionsSee Terminology A902 for definitions ofgeneral terminology relating to metallic-coated steel products,

18、 applies paint filmcoatings to coils of steel sheet on continuous paint lines.3.2.3 producer, nthe organization that produces the steelsheet coil product from which the cold-formed members arefabricated.3.2.4 purlins and girts, nhorizontal structural membersthat support roof deck or panel covering w

20、e to a mechanical condition of thetest specimen.3.2.7 roll former, nthe organization that produces thecold-formed members.3.2.8 zinc-iron alloy, na dull grey coating with no spanglepattern that is produced on hot-dip zinc-coated steel sheet.3.2.8.1 DiscussionZinc-iron alloy-coating is normallydull g
21、ray 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 product is intended to be paint
22、ed. 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 aesthetically objectionable to
23、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 aluminum-silicon alloycoating
24、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, and at scratches.3.2.10 alum
25、inum 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 in marine environments. Becau
26、se 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 ductility.NS, adjnonstructural.3.3.
