Sustainable roofing solution: The French construction company Ateliers 3S has developed the product “La Parisienne”, which emits 67% less CO₂ during production thanks to steel from ArcelorMittal.

The trapezoidal sheet “La Parisienne” is based on ArcelorMittal's Granite^® Storm technology. It uses XCarb^® recycled and renewably produced steel, manufactured from at least 75% steel scrap and melted in an electric arc furnace with 100% renewable energy. This results in a 67% reduction in the carbon footprint compared to the conventional blast furnace production method. In addition, Granite^® Storm is free of hexavalent chromium and heavy metals. The wrinkled surface is valued for its non-slip properties and durability, which are guaranteed for 30 years.

“La Parisienne” is available in six colors, offering planners and architects a wide range of aesthetic options. Ateliers 3S has set itself ambitious environmental goals and plans to gradually convert its entire product range to using XCarb^® steel from ArcelorMittal.

“We revisited a traditional recipe on one of the most tried and tested products in our business. Materials, coatings, design, we have worked on all the ingredients to make one of the most widely used roofing panel solutions a sustainable, high-performing and aesthetically pleasing choice; one that will continue to be as relevant in years to come as it has been in the past. For us as a construction company, the connection between design, functionality and climate protection is fundamental. We have been working with ArcelorMittal since our foundation. With the XCarb^® Recycled and Renewably Produced steel, we are able to offer 'La Parisienne' as a product with a very low carbon footprint, while at the same time providing an aesthetically pleasing and competitive solution,” explains Ateliers 3S managing director Julien Faisandier.

Patrick Le Pense, marketing manager at ArcelorMittal Europe – Flat Products says: “The fact that our CO₂-reduced XCarb^® technology is being used in an increasing number of applications in a wide range of industries is a great vote of confidence for us. Even today, the possibilities for building in a way that is both modern and sustainable are already extensive. And the trend is increasingly moving in this direction. The trapezoidal sheet metal “La Parisienne” is a prime example of how environmental protection and the circular economy can be incorporated into construction projects.”

Trade visitors to BAU in Munich from January 13 to 17, 2025 will be able to see a model of the trapezoidal sheet metal “La Parisienne” on stand B2.513. At the world's leading trade fair for the sector, ArcelorMittal Europe will be presenting on stand B2.319 its product range for the entire construction industry, resource-saving examples and steel solutions with a significantly reduced CO₂ footprint.
