Aurubis offers copper for roofs and façades treated with a variety of factory-applied surface treatments to create various stages of oxidation and patination. The surface finishes in the Nordic Copper range include varying intensities of brown oxidation and green or blue pre-patination. Aurubis provides prefabricated systems for the material as well.
A copper, aluminum and zinc alloy with a rich golden through-color. Nordic Royal has a thin protective oxide layer that will thicken when exposed to the atmosphere. The material will incorporate a matte, golden-brown surface finish and does not develop a blue or green patina except in exceptional environments such as coastal or humid regions.
Nordic Royal can be combined with other surface finishes such as Nordic Bronze or Nordic Brown for various visual effects.

|Maximum width ||1,000 mm |
|Delivery forms ||Sheet, coil |
Copper sheets and strips go through a carefully controlled pre-oxidization and pre-patination process to immediately provide the same brown oxidized and green or blue patinated surface that would develop naturally over. The pre-patination process encourages the natural patina to continue forming through environmental exposure, dependent on the local atmosphere and rainfall.
Custom-Made Surface Finishes and Forms
Aurubis regularly works with designers to explore custom-made copper surface finishes and forms. Custom options can include:
- Imaging or text printing surfaces
- Profiled sheets and pressed surfaces
- Perforated or expanded copper sheets
Planning and Installation Support
Aurubis can achieve different architectural effects of texture and scale using different installation techniques and systems – ranging from traditional standing seam sheet installation to panels, cassettes and other pre-fabricated systems.
