TECU Brass Brownished Roof and Facade Cladding

Brand: KME®

TECU® Brass Brownished offers the refined mineral surfaces sought by architects and designers. With four different shades (extra-light, light, middle, dark) and two finishing options (linear and circular ground), it brings a rich expression to the brass alloy. A light wax protection applied after grinding and burnishing highlights the surface texture while preserving its elegance for a long time. TECU® Brass Brownished creates a strong, sophisticated, and characterful design language—especially for soffits, parapets, entrance façades, and high-quality interior spaces.
