„Pre-oxidised copper for Roofing and Façade Cladding“
As if touched by nature, in magnificent shades of brown
Time-tested TECU ® Classic quality copper with a completely different look: With TECU ® Oxid, the initial weathering phase and the gradual brown colour change are simply bypassed. Natural changes on the building start immediately with a brown oxide layer. The process continues as with classical copper: Nature changes the surface through the effects of sun, rain, snow and wind, giving it an exciting life of its own – always unique, typical copper.
TECU ® Oxid copper sheets and strips are pre-oxidised on both sides in a patented industrial process that is gentle on the material. The oxide layer is not artificial but results naturally from the copper itself.
“To plan your design today going on how copper will look tomorrow? Why not? Why wait?”
TECU® Oxid strips are manufactured in state-of-the-art production facilities according to DIN EN 1172 and KME’s own strict guidelines. They are made of Cu-DHP-oxygenfree, phosphorus-deoxidised copper with limited residual phosphorus. Cu-DHP is well suited for welding and soldering; its degree of purity is at least 99.9 %, in accordance with DIN 1787 “Copper, Wrought Products”. Cu-DHP is outstandingly malleable, regardless of temperature and the direction of rolling.
TECU® Oxid surpasses the requirements of DIN EN 1172 with regard to tolerances and the most important technological values. This gives the processed surfaces their excellent visual appearance.
“Its warm, natural vibrancy is absolutely unique.”
Right from the start, TECU® Oxid has the aesthetic qualities of the oxidised matt brown surface, that gradually develops on bright copper surfaces as a result of weathering and oxidation. The copper strips are pre-oxidised on both sides in a special industrial process, anticipating years of atmospheric influence. The special manufacturing technology used creates lighter and darker shades of brown, but these colour variations later disappear as the natural oxidation process progresses. The matt brown surface continues to develop, turning from greyish brown to dark brown and then to anthracite. The matte brown surface transforms into dark brown and finally to anthracite; on sloping surfaces, a patina green, typical for copper, develops through the influences of substances in the air and moisture.
The lively protective layer lends TECU® Oxid its unmistakable appeal and extraordinary durability.
The physical appearance of TECU® is influenced by the installation and the system applied. The combination of copper’s typical properties, such as malleability, high ultimate elongation, high melting point etc. lend TECU® Oxid its special suitability for all metal-specific processing techniques from traditional seaming to modern cladding. TECU® Oxid can be processed like bright rolled copper using standard techniques and machines. However, due to the special features of the Oxid surface, a few important guidelines as to processing, material properties, transportation and storage should be kept in mind.
