- 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® HDXtreme and Granite® Storm 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® makes solar energy generation durable21 September 2023
The longevity of solar installations is directly dependent on the quality of the materials used to build them. Today, renewable energy producers expect their solar investments to have a productive lifetime of 25 years or longer. When it comes to selecting materials for the support structures for PV panels, factors such as low maintenance costs and ensuring the structural stability of the installation drive material choices. For the past ten years there has been a standout choice: Magnelis® from ArcelorMittal Europe – Flat Products.Product news
Commitment to sustainability sees Bruynzeel Storage Systems aim for net-zero by 204510 July 2023
Bruynzeel Storage Systems is a leading provider of made-to-measure storage solutions for archives, museums, retail, offices, libraries, smart warehouses, healthcare, and vertical farming. The company is a leader in sustainability, having already achieved climate neutral status in its own operations for Scope 1 and Scope 2 emissions. The next step is to decarbonise the company’s operations fully by achieving net-zero indirect emissions. Bruynzeel has set itself the goal of achieving this target by 2045 at the latest. To help Bruynzeel on that journey, the company has begun to purchase ArcelorMittal steels with XCarb® green steel certificates.“At Bruynzeel Storage Systems, we want to be the leader in our sector when it comes to enhancing the sustainability of our business,” says Bart Sijben, Chief Operating Officer (COO) of the company. “With that in mind, we have already taken action to create a climate-neutral factory. That has reduced our Scope 1 and Scope 2 emissions to zero. Now we are working to decarbonise our indirect – Scope 3 – emissions.”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.

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.
