TECU Oxid Roof and Facade Cladding

Brand: KME®

TECU® Oxid brings copper’s deep brown oxide tones—shaped as if touched by nature—into architecture from the very first day. By accelerating the time-consuming colour transformation of bright copper, it initiates the oxidation process immediately through its natural oxide layer. Pre-oxidised on both sides, the material continues to evolve with sun, rain, and wind, creating a unique and timeless character on every façade.
