Bright new architectural copper. TECUĀ® Classic sheet and coil starts off with a bright and shiny copper surface. After installation, it develops a matt, dark brown surface due to natural weathering and oxidation. During initial weathering, before the dark brown oxidised layer is established on the coppers surface, a range of brown shades and even purplish hues can develop. On inclined cladding areas, the oxide layers are transformed by more intensive reaction to airborne substances and moisture, and coloured alkaline copper compounds form. A typical copper patina green develops over time. This lends the building an unmistakeable accent, and the protective nature of the patina layer contributes to the materials outstanding longevity.
