Discover the game-changer that is Magnelis®
25 April 2024ArcelorMittal's Magnelis® is a game-changer in the world of metallic coatings, offering unparalleled corrosion protection.As the choice of professionals, Magnelis® stands out in the market, not just for its exceptional quality but also for its innovative formulation. It is manufactured using a continuous hot dip galvanising process where it is immersed in a unique molten bath composed of zinc, 3.5% aluminium, and 3% magnesium, giving it its distinctive chemical properties. Thanks to its unique composition, Magnelis® provides an unprecedented level of surface and cut-edge protection, even in the most hostile environments.
Product newsArcelorMittal Asturias becomes a benchmark plant for the production of Magnelis®
27 March 2024ArcelorMittal has begun mass production of Magnelis® steel at its galvanising line no. 1 in Avilés, Spain, making the Spanish site one of the main Magnelis® production plants within the ArcelorMittal Group. ArcelorMittal’s Magnelis® is a metallic coated steel that offers exceptional corrosion resistance and ensures optimal surface protection against long-term wear and tear.

Technical information
Magnelis® is a flat carbon steel coated on both sides with a zinc-aluminium-magnesium alloy*
- Excellent corrosion resistance - at least 3 times better than galvanised steel in external applications
- Complete edge protection thanks to the self-healing properties of Magnelis® on cut edges
- Outstanding resistance in harsh environments (maritime, chloride, and ammonia atmospheres)
- More cost-effective than batch galvanised steels due to simple manufacturing
- Reduced maintenance costs compared to post painting
Magnelis® has a uniform metallic look, which may appear slightly matt to bright. Variations in appearance and a tendency to darken are possible. Corrosion protection is not impaired by this visual change.
The excellent corrosion resistance properties of Magnelis® have been accredited with a Preliminary Technical Evaluation of Material (ETPM) by CSTB (Centre Scientifique et Technique du Bâtiment) and certified by a number of other external bodies, among them SP (Science Partner) and DIBT (Deutsches Institut für Bautechnik).
* This alloy is composed of 93.5% zinc, 3.5% aluminium, and 3% magnesium.
