TECU Bronze Roof and Facade Cladding

TECU Bronze Roof and Facade Cladding

NEO | METAL
Brand: KME®
TECU® Bronze is born from the noble combination of copper and tin, offering architecture a new perspective. Long valued in art, bronze now delivers a strong and refined expression in façade design. Its warm reddish-brown surface gradually evolves into brown-grey undertones and eventually into a dark anthracite character. Compared to pure copper, its slower and more controlled patina development gives façades a lasting, refined, and timeless identity.
