TECU Brass Roof and Facade Cladding

TECU Brass Roof and Facade Cladding

NEO | METAL
Brand: KME®
TECU® Brass is a modern and expressive façade material developed from a special alloy of copper and zinc. Its lively and durable structure adds strong character to architecture, while the surface gradually matures from greenish-brown tones to dark anthracite hues. On sloped surfaces, it develops a distinctive natural patina—clearly different from pure copper—giving each façade its own living identity.
