1.1 This specification covers zinc coatings applied by the electrolytic process to hot-rolled and cold-rolled steel sheet. The coating has a smooth, spangle-free surface. The zinc-coated sheet covered in this specification is produced in a wide range of coating masses to provide coatings that are compatible with the service life required. The coating mass varies, from very thin coatings that are usually painted to provide good service, to relatively heavy masses that provide good corrosion resistance in the bare (unpainted) condition.
1.2 The product shall be coated on one or both surfaces and may have equal or differential coating masses on the two surfaces. Sheet coated with equal coating masses on each surface would have 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. Thus one surface is specified to have heavier coating mass than the other. Either surface, when specified to be painted will provide additional corrosion protection as compared to an unpainted surface.
1.3 This coating process has essentially no effect on the base metal mechanical properties and can be used on any grade or quality of hot or cold-rolled steel sheet. The coated sheet is available as Commercial Steel (CS), Drawing Steel (DS), Deep Drawing Steel (DDS), Extra-Deep Drawing Steel (EDDS), Structural Steel (SS), High -Strength Low -Alloy Steel (HSLAS), or High-Strength Low-Alloy Steel with Improved Formability (HSLAS-F).
1.4 The values stated in SI units are to be regarded as the standard.
