This Malaysian Standard specifies continuous hot-dip zinc-aluminium alloy, zinc-aluminium-magnesium alloy and aluminium-zinc-magnesium alloy coated carbon steel sheet in terms of structural quality, commercial quality and drawing 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. Metallic coated steel sheet is produced in thickness range from 0.16 mm to 5 mm after hot-dip metallic coating, and in widths of 600 mm and above in coils and cut lengths. Metallic coated steel sheet less than 600 mm wide may be slit from wide sheet and will be considered as strip.
