Copper Roofing Products

Copper strips and sheets for roofing are made of CU-DHP, i.e. oxygen-free, phosphorus-deoxidised copper with limited residual phosphorus content. Cu-DHP has very good weldability and solder ability; it can be excellently formed regardless of temperature and rolling direction and is corrosion resistant and requires little maintenance.  

Copper is a traditional and versatile material that has long been used for roof drainage and roofing of historical and contemporary buildings. Its characteristic surface makes the material an extremely lively, profile-forming design element for architects and building owners, which harmonises perfectly with natural building materials. 

Copper sheets and strips initially have the optical quality of the bare copper surface. After installation on site, a matt dark brown colour develops under the influence of atmospheric weathering through oxidation. On inclined surfaces, the oxide layers continue to change colour due to the intensive action of air constituents and moisture, forming basic copper compounds. Over the course of time, the green patina typical of copper develops, which gives buildings their unmistakable accent and, in addition, its protective properties ensure the extraordinary durability of the material.
