Metallic Coated Steels

Technical details

Metallic coated steels are steel substrate coated with:

  • a layer of zinc, defined as Z coating. The coating process can apply very thick zinc layers, up to 725 g/m² (total of both sides)
  • a layer of zinc/aluminium alloy, Galfan (ZA), composed of 95% zinc and 5% aluminium 
  • a layer of aluminium/silicium alloy, Alusi® (AS),  composed of 90% aluminium and 10% silicon 
  • a layer of zinc/aluminium/silicon alloy, Aluzinc® (AZ), composed of 55% aluminium, 43.4% zinc and 1.6% silicon. 
  • a layer of zinc/aluminium/magnesium coating, Magnelis® (ZM), composed of 93.5% zinc, 3.5% aluminium and 3% magnesium
  • a layer of pure aluminium coating, Alupur® (AL). Alupur® is a steel substrate coated on both sides with pure aluminium.

These products are manufactured on continuous production lines using different coating processes such as:

  • Hot dip coating process, whereby the steel strip is immersed in a bath of molten metal. 
  • Electrogalvanising process, in which metal is deposited electrolytically on the cold steel strip
  • Coating under vacuum, such as PVD (Physical Vapour Deposition), CVD (Chemical Vapour Deposition)
  • Jet Vapor Deposition process (JVD), a process to obtain a homogeneous coating on one or both sides of the steel

Best Corrosion Resistance Performance

Discover our full range of metallic coated steels for all types of construction applications:  

  • Aluzinc® and Aluzinc® Florelis for facade and building envelope such as roofing, cladding, structural sections, composite panels, tiles
  • Aluzinc® HFX for seam roofs, which is the best alternative to metallic Zinc profiles & sheets, at a much lower cost
  • Galfan is used for structural or trim members, metallic ceilings, partitions and partition panels, doors, guttering, metallic door frames, swimming pools, road signs, greenhouses etc
  • Alusi® can resist high temperatures, it is particularly suitable for thermal shieldings like for fire doors
  • Alupur® is an excellent solution for many applications in power plants and the petrochemical industry
  • Magnelis® shows outstanding resistance in harsh environments with self-healing properties on the cut edges. This steel product is widely used for rainwater systems, light steel framing, lighting poles and road equipment, animal housing, silos, greenhouses as well as solar structure.

Metallic coated steel is certainly the product best able to meet present and future environmental regulations. ArcelorMittal has opted for a proactive approach to the evolution of these regulations by building respect for the environment into the life cycle of its metallic coated steel products.
