TECU® Patina

Using a specially developed industrial process, TECU® copper sheets are patinated green on one side.

This process causes an oxidised layer to form on the surface of the copper – a process similar to the natural patination that occurs over a long period of time when copper is exposed to atmospheric conditions. This is not an artificial colouring or coating process. TECU® Patina gives cladding the green patina colour typical of copper right from the start.

TECU® Patina does away with the waiting time otherwise necessary until the pitched surfaces eventually turn green as a result of the natural effects of weathering. Roofs, façades and rainwater systems have the green patina that is unique to copper right from the outset.

The patina continuously changes and develops when exposed to atmospheric conditions. The resulting variations in colour are proof of just how natural the patina surface is.

TECU® Patina offers unique possibilities for demanding design solutions in modern architecture. The many prize-winning buildings that have been constructed using this extraordinary material are compelling evidence of ist unique design potential.
