Our textured stainless steel is a great material for large scale projects — it comprises the largest roof of its kind at Hamad Int’l. Airport.

Rigidized® Metals’ InvariMatte® micro textured stainless steel clads the roof of the Hamad International Airport in Doha, Qatar. This is the largest stainless steel roof in the world at 6.5 million square feet. The micro texture reduces glare, and provides both thermal and solar reflectance, which saves energy. Additionally, the micro texture provides easy clean-ability and durability, requiring little to no maintenance for the entire life of the building.
