Aluzinc®: steels with aluminium-zinc coating

Aluzinc® steels with aluminium-zinc coating

Aluzinc® is a steel substrate coated on both sides with an aluminium-zinc alloy. The composition of the coating is: 55% aluminium, 43.4% zinc and 1.6% silicon.
The excellent corrosion resistance of Aluzinc® is a result of the properties of the two metallic substances: the barrier effect of the aluminium present on the surface of the coating and the sacrificial protection of zinc.

Thanks to a thin transparent layer of aluminium oxides on the top surface of the coating, this appearance is preserved when aging.
Aluzinc® offers additional advantages:

    - Good corrosion resistance at high temperatures
    - Good abrasion resistance because of its surface hardness
    - Excellent thermal and light reflectivity

Aluzinc® can be supplied oiled and/or with a chemical surface conversion, or with an Easyfilm® thin organic coating.
