- ArcelorMittal's best in class product for corrosion resistance is Magnelis® metallic coated steel. It is THE solution to corrosion in the harshest environment, even for deformed parts. The specific composition of Magnelis® (3% Mg and 3.5% Al) is the key element which ensures a stable and durable layer across the entire surface and self-healing characteristics for edges, scratches, and perforations.
- Indaten® for flat products and Arcorox® for sections are weathering steels developed by ArcelorMittal. Weathering steels are well known as corrosion resistant steels thanks to the addition of copper during manufacturing. Corrosion resistance can be improved even further by using phosphorous with the exception of the structural heavy plate to avoid iron phosphide (FeP3).
- Granite® HDX, Granite® Storm & Solano® Nature organic coated steels have excellent corrosion resistance up to RC5 and are ideal for external usage in severe environments for components such as profiles and sandwich panels for roofing and cladding. They are also suitable for roofing applications such as tiles, guttering, and rainwater systems.
- Sheet piles can be delivered with a specific coating adapted to marine environment and soil conditions.
Magnelis® goes green28 September 2018
Magnelis® brings a touch of nature to your facadesVegetal exterior walls, or “green walls,” are a great way to bring nature to the facade of buildings and give them a unique look. Green walls are designed either as aesthetic elements for interior or exterior décor - sometimes as works of art using plants or as elements of urban ecology. For instance, a green wall is one of the elements that makes the facade of the Musée du quai Branly in Paris so unique.Product News
Magnelis® at the centre of ArcelorMittal Fos-sur-Mer’s first solar farm20 February 2018
ArcelorMittal Méditerranée recently inaugurated a photovoltaic farm on its site of Fos-sur-Mer, realised in partnership with EDF Energies Nouvelles. This solar farm of 15 hectares has a capacity of 12 MWc, equal to the annual electricity consumption of 7,400 citizens, half of the town of Fos-sur-Mer. Profil du Futur, a division of ArcelorMittal Construction, was in charge of the structure’s construction and used Magnelis®,a lead product of ArcelorMittal Europe – Flat Products for solar projects.Project News
Dubai’s massive solar project gets Magnelis® protection15 November 2017
The Mohammed bin Rashid Al Maktoum Solar Park in Dubai (UAE) is the world's largest single-site renewable-energy project. The latest section of the Park to come onstream uses structural steels protected with Magnelis®, ArcelorMittal’s innovative breakthrough in corrosion protection. Thanks to its unique composition, Magnelis® will provide the solar structure with an unprecedented level of surface and cut-edge protection, even in this hostile desert environment.Project News
Magnelis® PV frame by Hanwha Q CELLS wins 2017 Intersolar award10 August 2017
A new steel mounting system developed by Hanwha Q CELLS has won a 2017 Intersolar innovation award. The revolutionary design replaces traditional aluminium frames which support the photovoltaic (PV) modules on a solar mounting rack. By utilising ArcelorMittal Europe – Flat Products’ breakthrough Magnelis® coating, Hanwha Q CELLS have significantly reduced the carbon footprint and cost of PV installations.Product News
ArcelorMittal Europe has extensive experience and knowledge of developing and offering best in class products and solutions for corrosion resistant steels in the harshest environments.
Corrosion is an electrochemical process where an electrochemical cell is created consisting of an anode, which is depleted to the benefit of a cathode. In practice, cells are formed as soon as a lack of surface uniformity appears creating anode and cathode areas whereby water acts as the electrolyte. In these cells, the steel will corrode each time it becomes the anode, but when it is the cathode, it will remain intact. Corrosion phenomena occur under the action of a corrosive medium and finally lead to erosion of the material.
When it comes to steel, the result may be the visible corrosion product known as rust, which may cause deterioration of the external appearance, and finally, lead to the loss of performance capacity of steel members as well as damage other components.

Magnelis® in Agriculture Applications
The risk of corrosion depends on the environment in which a material is utilised. The corrosion risks of different ambient conditions have been classified in the ISO EN 12994 standard. The classifications start at C1 (non-aggressive environment) and go up to C5 (most aggressive). Distinctions are made between indoor and outdoor environments.
