Cladding

Copper for cladding

Copper is a natural material that weathers when exposed to the elements. Over the course of a number of years copper will change naturally from red, through brown, to green. Manufacturers now have factory methods that can apply both patinated and oxidised surfaces straightaway. Copper, comes in a number of finishes: Bright (red), Oxidised (dark brown) and Patinated (blue-green).

Alloys of copper are also available, giving designers further choices. Brass is an alloy of copper and zinc, a golden colour that will weather to dark brown. Bronze is an alloy of copper and tin, a warm red-brown colour which changes in time to a dark brown. Special copper alloys are available that retain their overall golden appearance.

Copper and copper alloys are available in sheets and, more recently, in meshes and expanded metal which give an air of transparency.
