1.1 This European Standard specifies requirements for continuously hot-dip aluminium-zinc alloy
coated flat products made of low carbon steels for F cold forming (see table 1) or of structural steels (see table 2) in thicknesses ≤ 3,0 mm. The thickness is the final thickness of the delivered product after coating.n
This European Standard applies to strip of all widths and to sheets cut from it (≥ 600 mm width) and cut lengths (< 600 mm width).
The aluminium-zinc alloy composition by mass is nominally 55 % Al, 1,6 % Si, and the balance zinc.
The available coating masses, coating finishes and surface qualities are given in 5.2 to 5.4 and table 3.
1.2 The products covered by this European Standard are mainly intended for applications where the protection of the steel base against corrosion is of prime importance.
1.3 This European Standard is not applicable to: continuously hot-dip zinc-aluminium alloy (ZA) coated steel flat products (see EN 10214);
- continuously hot-dip zinc coated low carbon steel sheet and strip for cold forming (see EN 10142);
- continuously hot-dip zinc coated structural steel sh and strip (see EN 10147);
- electrolytically zinc coated steel flat products (see EN 10152);
- continuously organic coated flat steel products (see EN 10169, in preparation).
