Copper Finishes

Finishes

Natural

Initially, the material has the aesthetic qualities of the bright copper surface which, on exposure to the atmosphere, slowly changes to dark brown as the oxide layer forms and later develops copper's typical green patina layer on pitched surfaces.

Oxid

Oxid is copper that is specially treated in a patented industrial process in which strips are oxidised on both sides. With Oxid, the bright copper phase is bridged so that a uniform, dark brown oxidised layer is achieved even before the cladding is laid. This is not an artificial colouring process or coating, but rather an oxidised layer which is created from the surface of the copper itself. The surface further develops into the natural oxide layer in the course of weathering. The special manufacturing technology used produces lighter and darker shades of brown.

Pre-Pat

Using a specially developed industrial process, copper sheets are patinated green on one side. This process causes an oxidised layer to form on the surface of the copper – a process similar to the natural patination that occurs over a long period of time when copper is exposed to atmospheric conditions. This is not an artificial colouring or coating process. Patina does away with the waiting time otherwise necessary until the pitched surfaces eventually turn green as a result of the natural effects of weathering.

Zinn

Zinn (matt grey, tinned) natural copper that has been specially tinned and surface-treated on both sides to create a matt grey surface. The surface continues to develop further over time on exposure to the atmosphere. The result is a warm, matt grey colour which harmonises excellently with other building materials. This material gives architects looking to create a light, grey surface many interesting design possibilities. When using Zinn they also get all the technical advantages of copper, such as durability and workability in cold temperatures.

Brass
	With a reddish golden surface for impressive new façade solutions using copper. Brass is a CuZn15-grade copper and zinc alloy that has been specially designed for use on façades. Weathering changes the original reddish golden colour of the surface in a very lively manner, with each façade developing its own unique characteristics. After the initial matting, the surface

Bronze

With a superior, reddish brown surface for impressive new façade solutions in copper. Bronze is an alloy of CuSn4 grade copper and tin. The original warm reddish-brown colour of the surface develops in a characteristic manner through weathering. Typical for this alloy is a brown-red oxidation of the surface with a brown-grey colouring underneath; the material then very gradually changes to dark brown anthracite throughout.

Gold

With a precious golden surface for impressive new façade solutions using copper. Gold is a copper and aluminium alloy. The original shiny golden colour of the surface goes through characteristic changes when exposed to normal weathering. After the initial matting, a golden and yellowish oxidation layer gradually emerges, and this changes over time into a soft golden colour. The patination processes do not give rise to any further intensive colouring on façade surfaces.
