Properties


Aluzinc Steel Coil 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 Coil 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 Coil 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 Coil 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 Coil 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 Steel Coil 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®). DX56D AM FCE +AZHFX +Easyfilm®is suitable for standing seam applications in roofing and cladding.

Aluzinc Steel Coil 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 Coil 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.

Forming and joining
The forming and joining techniques currently used for uncoated steel sheets are also suitable for Aluzinc Steel Coil.
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 Coil is coated with an Easyfilm® thin organic coating.

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