  • INQUIRY
Aluzinc coated steel Coil 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 Steel 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 Steel offers additional advantages:
- Good corrosion resistance at high temperatures
- Good abrasion resistance because of its surface hardness
- Excellent thermal and light reflectivity

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

Properties
Aluzinc Steel 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 Steel 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 Steel 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 Steel 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 steel coil offers additional advantages:
Good corrosion resistance at high temperatures
Good abrasion resistance because of its surface hardness
Excellent thermal and light reflectivity

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

Aluzinc Steel 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 Steel 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 EasyfilmSteel coating.

Forming and joining
The forming and joining techniques currently used for uncoated steel sheets are also suitable for Aluzinc Steel.
Aluzinc Steel cladding The coating thickness must therefore be compatible with both the desired degree of corrosion protection and the requirements of the forming and welding processes envisaged. Forming performance is improved if Aluzinc Steel is coated with an EasyfilmSteel thin organic coating.

Painting
Aluzinc Steel can be painted after degreasing and surface treatment when delivered oiled. Aluzinc Steel coated with an EasyfilmSteel thin organic coating can be painted directly, without any prior surface treatment. However, the paint must be compatible with the EasyfilmSteel resin.

Weldability
In electrical resistance welding, the welding current must be suitably regulated and regularly adjusted. Electrode life can be extended by regularly stepping up the welding current and periodically dressing (machining) the electrodes.
