1 This International Standard applies to carbon steel sheet of commercial and drawing qualities coated by the continuous hot-dip zinc-coating process.
2 Zinc-coated sheet is suitable for applications where resistance to corrosion is of prime importance.
3 The steel sheet is produced in a number of qualities, coating mass, surface treatments, and ordering conditions.
4 Zinc-coated sheet is produced in thicknesses from 0,25 mm to 5 mm inclusive after coating, and in widths of 600 mm and over in coils and cut lengths. Zinc-coated sheet less than 600 mm wide, slit from wide sheet, will be considered as sheet.
5 The thickness of hot-dip zinc-coated and zinc-iron alloy sheet steel may be specified as a combination of the base metal and metallic coating, or as the base metal alone. The purchaser shall indicate on the order which method of specifying thickness is required. In the event the purchaser does not indicate any preference, the thickness as a combination of the base metal and coating will be provided. Annex A describes the requirements for specifying the thickness of the base metal alone.
6 Zinc and zinc-iron alloy coated steel sheet may 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.
7 Zinc-coated steel sheet is available in several fabrication qualities.
— Commercial: intended for general fabrication purposes where sheet is used in the flat or for bending or moderate forming.
— Drawing: intended for fabricating parts where drawing or severe forming may be involved.
— Deep drawing-aluminium killed (non-aging): intended for fabricating parts where particularly severe drawing or forming may be involved or essential freedom form aging is required.
— Extra deep drawing (stabilized interstitial free): intended for applications requiring interstitial free steel (IF) which is non-aging and has maximum formability.
8 This International Standard does not cover steels designated as structural quality which are covered in ISO 4998 .
