Industry newsMagnelis® steel outperforms galvanised steel in soil
28 February 2022The complexity of corrosion mechanisms has made it difficult to establish norms and standards for solar steel structures in soils. Thanks to its extensive research, including laboratory and outdoor testing over a number of years, ArcelorMittal has proven that Magnelis® has a much more stable behaviour and much better resistance against corrosion compared with traditional zinc coatings. The French Corrosion Institute confirmed in December 2021 that Magnelis® behaves 3.8 times better than galvanised steel.

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
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.
