The classic bright rolled solution. A "living” surface which changes over the course of time. Copper has a special character which gives any building a more distinguished look. |
What normally takes years can be realised immediately: a green patina. This finish produces a striking effect in modern architecture, is attractive in combination with other building materials and is important for restoring historical buildings. |
Pre-oxidised by a special process, this surface is brown from the outset. No unsightly processing marks become visible. |
The matt-tinned finish combines the technical advantages of copper, such as resistance to condensation and workability at any temperature, with an attractive grey colour. |
