标准简介：This International Standard applies to continuous hot-dip zinc- and zinc-iron-alloy-coated carbon steel sheet of structural quality.
The product is intended for applications where resistance to corrosion is of prime importance.
The steel sheet is produced in a number of grades, coating mass, ordering conditions, and surface treatments.
Zinc-coated structural quality sheet is produced in thicknesses from 0,25 mm to 5 mm after zinc coating, and in widths of 600 mm and over in coils and cut lengths. Zinc-coated sheet less than 600 mm wide may be slit from wide sheet and will be considered as sheet.
NOTE   Thicknesses less than 0,4 mm may not be available in grades 220, 250, 280 and 320.
The thickness of zinc and zinc-iron alloy coated sheet steel may be specified as a combination of the base metal and metallic coating, or base metal alone. The purchaser shall indicate on the order which method of specifying thickness is required. In the event that 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 as base metal alone.
This International Standard does not cover steels designated as commercial quality, or drawing quality, which are covered in ISO 3575 <up[2]>.
