Indaten™ Weathering Steel

Indaten™ is a cold rolled weathering steel that combines atmospheric corrosion resistance and structural strength. Designed for exterior building panels and roofing without metallic or organic coatings; it is easily roll formed into a variety of profiles. Over time, the steel surface develops a unique purplish-brown, finely grained patina when exposed to alternating wet and dry outdoor weather conditions in a non-aggressive environment.
