With TECU® Oxid, the initial bright, freshly-installed copper, and the gradual change of colour to shades of brown is simply bypassed. Natural changes on the building start immediately with a dark 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.
