ArcelorMittal presents sustainable and circular steel solutions at the BAU trade fair in Munich

BAU 2027, the world's leading trade fair for building materials, will take place in Munich from 11 to 15 January 2027.
ArcelorMittal will present its broad portfolio of steel solutions building envelopes, roofs, façades and the integration of renewable energy.
The focus of this year is on the interplay between material efficiency, durability, low-carbon manufacturing and recycling.

Magnelis^® – long-lasting protection for steel structures

Magnelis^® is a metallic coating with high corrosion resistance and is suitable, amongst other things, for substructures and applications in the construction sector. Its high resistance ensures a long service life for the components and thus promotes the efficient use of resources.
Magnelis^® can be combined with low-carbon XCarb^® steel as well as with high-strength grades. One example is S550GD-HyPer: its higher strength makes it possible to design structures using less material and with reduced space requirements. S550GD-HyPer is DIBt-certified and Eurocode-compliant.

On our stand, our partner Sweelco will present a large light steel frame, and outline its advantages in terms of lightness compared with wood, 50% faster speed of construction, and durability.

 

Zambelli, partner in the area of rainwater systems, will also showcase a demonstrator of its FERRODUR^® system, easy to install, down to -15°, and guaranteed up to 45 years against perforation.

Both solutions are made with and Protected by Magnelis^®.

Granite^® – high-performance surfaces for roofs and façades

With Granite^®, ArcelorMittal offers organically coated steels specifically for demanding roof and façade applications.

Granite^® HDS 45 is characterised by high UV and corrosion resistance as well as good formability, and is particularly suitable for roof surfaces with solar installations. The product is REACH-compliant and DIBt-certified.

Granite^® HDXtreme is designed for particularly long-lasting roof and façade applications. The product comes with a guarantee of up to 40 years. A range of 50 colours and three surface finishes also opens up a wide variety of architectural design options.

Different finishes are available, including anti-slip ones. Picture © Bancha khaomim/Shutterstock.com adapted by Philippe Vandenameele

XCarb^® recycled and renewably produced – low-carbon steel as the basis

ArcelorMittal steel can be supplied using XCarb^® recycled and renewably produced low-carbon steel. This approach combines up to 100 per cent recycled steel with renewable electricity in production, thereby significantly reducing the CO₂ emissions associated with steel manufacturing.

Together with material efficiency, durable products, and reuse and recycling, CO₂-reduced production forms a key building block for circular construction.
