Magnelis® compliant with European norm EN 10346:2015

Magnelis®, ArcelorMittal’s leading zinc-aluminium-magnesium coating which offers unbeatable corrosion resistance in even the harshest environments, is now recognised as compliant with the new European standard EN 10346:2015.

The European standard EN 10346, related to hot dip galvanized (HDG) products, was extended in July 2015 to include zinc-aluminium-magnesium coatings. Whenever norm compliance is a prerequisite, architects, engineers and construction companies can now propose Magnelis®. Magnelis® is the preferred material for an increasing number of applications, including solar support structures, light steel framing in construction, agricultural applications and road infrastructures.


The new norm is a tribute to the success of Magnelis®, which has proven its advantages over standard hot dip galvanized products and offers a guarantee of up to 25 years depending on the applications and environments.

Magnelis®, a unique metallic steel coating composed of 93.5% zinc, 3.5% aluminium and 3% magnesium, is proven to offer up to ten times better protection against atmospheric corrosion than ordinary galvanised steel. The 3% magnesium in Magnelis® is key as it leads to the creation of a stable and robust layer across the entire metal surface, providing a far more effective defence against corrosion than coatings with a lower magnesium content.

In terms of cost-efficiency, Magnelis® provides the best alternative to galvanized products, as well as stainless and aluminium. Magnelis® coatings offers the possibility to drastically increase the corrosion performance or to offer with a strongly reduced coating layer the same level of corrosion resistance of standard galvanised products.

Magnelis® is also much better for the environment, notably demonstrating significantly reduced zinc runoff into the soil.
