ArcelorMittal has inaugurated its Helioroof® production line in Contrisson, France, introducing a roofing product that combines steel roofing panels, thermal insulation, and solar cells while also delivering significantly lower carbon emissions compared with conventional products.
Ready-to-install and all-in-one, Helioroof® modules are custom-made, up to 12 meters in length, with an energy output of up to 2.1 kWp (kilowatt peak) per module.
Helioroof reflects ArcelorMittal Building Solutions’ commitment to sustainable construction. Material-efficient, Helioroof weighs half as much as a traditional roof with added solar panels, and has a carbon footprint that is 25% lower than traditional insulated steel roofs.
ArcelorMittal Building Solutions uses ArcelorMittal steel, including ArcelorMittal’s XCarb® steel. Between two steel sheets, the sandwich panel includes a layer which provides thermal insulation, while the top steel sheet directly integrates solar cells. All these components are assembled at the Contrisson site.
ArcelorMittal relied on the R&D teams of ArcelorMittal Building Solutions and its partner CRM Group (Belgium), a leading research center specializing in metallic materials and industrial innovation.
The industrial equipment was custom-designed for the Contrisson plant: an automated production line where quality is monitored at every stage, with extremely high standards. ArcelorMittal Building Solutions teams have developed and applied specific expertise from the solar industry, including working in a “gray room” environment to ensure the integrity of the solar cells.
