BS EN 10327:2004 specifies requirements for continuously hot-dip coated products made of low carbon steels for cold forming coated with zinc (Z), zinc-iron alloy (ZF), zinc-aluminium alloy (ZA), aluminium-zinc alloy (AZ) and aluminium-silicon alloy (AS) with thicknesses of 0.35 mm to 3.0 mm unless otherwise agreed. The thickness is the final thickness of the delivered product after coating.
This standard applies to strip of all widths and to sheets cut from it (greater than or equal to 600 mm width) and cut lengths (< 600 mm width).
This standard may also be applied to continuously hot-dip coated flat products in thicknesses > 3.0 mm.
The products covered by this standard are mainly used where cold formability and corrosion resistance are the most important factors.
This standard is not applicable to:
- continuously hot-dip coated structural steel flat products
- electrolytically zinc coated cold rolled steel flat products
- continuously organic coated (coil coated) steel flat products
- continuously hot-dip coated strip and sheet of steels with higher yield strength for cold forming.
BS EN 10327:2004 specifies requirements for continuously hot-dip coated products made of low carbon steels for cold forming coated with zinc (Z), zinc-iron alloy (ZF), zinc-aluminium alloy (ZA), aluminium-zinc alloy (AZ) and aluminium-silicon alloy (AS) with a thickness of 0.35 mm to 3.0 mm unless otherwise agreed.
This document applies to strips of all widths and to sheets cut from it (≥ 600 mm width) and cut lengths (< 600 mm width). If agreed at the time of enquiry and order, this document may also be applied to continuously hot-dip coated flat products in thicknesses > 3,0 mm. In this case the mechanical property, adhesion of coating and surface condition requirements shall also be agreed at the time of enquiry and order.
BS EN 10327:2004 is not applicable to continuously hot-dip coated structural steel flat products; electrolytically zinc coated cold rolled steel flat products; continuously organic coated (coil coated) steel flat products; or continuously hot-dip coated strip and sheet of steels with higher yield strength for cold forming.
