Aluzinc®: 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® Florelis

Aluzinc® Florelis is an Aluzinc® based material (55% Al, 43.5% Zn) with a guaranteed number of spangles (minimum 1000 per dm2 / maximum 1800 per dm2). Aluzinc® Florelis used with a coating thickness of AZ185 and comes with a warranty of 25 years.


Aluzinc® HFX

Aluzinc® HFX (High Formability eXtended) is a metallic coating combining the excellent corrosion resistance of conventional Aluzinc® with high formability properties, which makes it specially suitable for standing seem roofs.

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