ArcelorMittal Indaten™ Weathering Steel for Roofing & Siding

ArcelorMittal Dofasco

07 40 00 Roofing and Siding Panels

Indaten™ is a cold-rolled weathering steel that combines atmospheric corrosion resistance and structural strength, suitable for residential or commercial construction applications. Designed for exterior building facades, roofing, cladding, siding, and architecture without the use of metallic or organic coatings; it is easily roll-formed into a variety of profiles. Once installed, the exposed surfaces transition from an initial dark grey mill finish to an orange patina in several weeks. The patina continues to evolve, reaching its final dark purple-brown colour after several years – dependent on local weather conditions.
