scope:

This International Standard applies to carbon steel sheet of commercial and drawing qualities coated by the continuous hot-dip zinc-coating process. Zinc-coated sheet is suitable for applications where resistance to corrosion is of prime importance. The steel sheet is produced in a number of qualities, coating mass, surface treatments and ordering conditions. Zinc- and zinc-iron-alloy-coated steel sheet can be ordered in one of two ordering conditions. a) Condition A): steel ordered to satisfy mechanical property requirements. b) Condition B): steel ordered to make an identified part. This International Standard does not cover steels designated as structural quality, which are covered in ISO 4998.
