1.1 This specification covers hot-rolled and cold-rolled steel sheet coated by the electrolytic process. Coatings can be comprised ofpure metals or metal alloys. For specific coatings,refer to Specifications A879/A879M and A918.
1.2 The product shall be coated on one or both surfaces with equal or differential coating masses on the two surfaces.Sheet-coated with equal coating masses on each surface has similar levels of corrosion protection on each surface. Often,however, a higher level of corrosion protection is required on one surface than is required on the other. In these situations,one surface shall be specified with a heavier coating mass than the other. Either surface, when specified to be painted, will provide additional corrosion protection as compared to an unpainted surface.
