HVAC: Heating ventilation & air conditioning


Aware of the HVAC industry's challenges, ArcelorMittal provides you several products meeting the HVAC equipment needs: fighting corrosionaesthetic featuresweight reductionstrength and heat protection

Steel for both indoor and outdoor environments


Magnelis®: for corrosion resistant HVAC equipment

ArcelorMittal provides you an exceptional steel coating which provides breakthrough corrosion protectionMagnelis®

Magnelis® is produced on a classic hot dip galvanising line which molten bath has a unique chemical composition including Zinc, 3.5% Aluminium, and 3% Magnesium.

HVAC equipment can be at risk of oxidation due to condensation or extreme environments. This makes durability a key consideration when selecting materials for HVAC systems. As a durable coating with excellent corrosion resistance properties, Magnelis® is ideally suited for HVAC applications.


Steels coated with Magnelis® are highly suitable for heating, ventilation, and air conditioning (HVAC) equipment in many types of building including: residential, commercial, industrial, data centres, hospitals, marine structures, warehouses, waste treatment centres, swimming pools and sports centres, and agricultural buildings and animal housing.

Advantages of using Magnelis® for HVAC equipment

  • Durability improved for a longer life
  • Reduced maintenance costs
  • Cost-effective solution compared to post-galvanized steel, aluminium, and stainless
  • Excellent workability (forming, welding, painting) and protection after deformation
  • Self-healing effect on cut edges and perforations
  • 100% recyclable

Apply Magnelis®  to your HVAC components

Thanks to the innovative composition of Magnelis® and its compatibility with high strength steels, the coating is an ideal solution for durable casings, frames, structures, ducts, ventilators, blades, supports, containers, air handling units and ventilation grills in HVAC systems.

Alusi®: for corrosion and fire-resistant HVAC equipment

Alusi® is a metallic-coated steel covered on both sides by an aluminium (90%) and silicon (10%) coating. If the temperature of the heating system will exceed 200°C, ArcelorMittal recommends using Alusi®.

Alusi® offers

  • Heat resistance up to 800°C
  • Heat reflectivity
  • Corrosion resistance
  • RoHS compliance

Jetskin®: for corrosion resistant indoor HVAC equipment

Jetskin® is a metallic coating for steel which is applied using Jet Vapor Deposition (JVD). Jetskin® provides a homogeneous coating on one or both sides of the steel. It offers excellent corrosion protection particularly for indoor applications such as air conditioners and air curtains. Jetskin® behaves better than conventional electrogalvanised steel when it comes to resistance spot welding.
