Details:
 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 is a flat carbon steel product coated on both sides with an aluminium-zinc alloy. The coating is composed of 55% aluminium, 43.4% zinc and 1.6% silicon and applied by means of a continuous hot dip galvanising process. Aluzinc is available in a wide range of steel grades: steels for cold forming and deep drawing applications, and structural steels. 

Advantages

The excellent corrosion resistance of Aluzinc is a result of the properties of its two metallic constituents: the barrier effect of the aluminium present on the surface of the coating and the sacrificial protection of zinc.
The characteristic spangled silver colour of Aluzinc gives it a very attractive appearance. Thanks to a thin transparent layer of aluminium oxide on the top surface of the coating, this appearance is preserved over time.
Aluzinc offers additional advantages:
Good corrosion resistance at high temperatures
Good abrasion resistance because of its surface hardness
Excellent thermal and light reflectivity

Applications

Aluzinc coated steels are used widely in both indoor and outdoor applications:
Construction: roofing, cladding, structural sections, composite panels, tiles etc
Domestic appliances: washing machines, tumble dryers, refrigerators, toasters, microwave ovens etc
Miscellaneous: boiler casings, air ducts, electrical cabinets, lighting, computer casings etc

Aluzinc can be supplied oiled and/or with a chemical surface treatment, or with an Easyfilm® thin organic coating (please see data sheet E80 for the specific properties of Easyfilm).

Aluzinc Florelis is a product with improved uniformity, with the result that there is no visible difference between the sheets. It is specially designed for facades of buildings with the highest aesthetic requirements.

Recommendations for use
Storage
Aluzinc is supplied passivated or oiled to temporarily limit any risk of black rust formation. During transport and storage, all necessary precautions must be taken to keep the material dry and to prevent the formation of condensation. Improved protection can be obtained by the application of an Easyfilm coating.
