COPPER, BRASS & BRONZE FINISHES

Copper can be pre-patinated to a variety of colours. Greenish pre-patinated colours change less than others over the years. The colour of naturally formed patina for copper, brass and bronze depends on environmental conditions, typically resulting in a dark brownish matt surface. Each alloy will attain a different hue. Nordic Royal is alloyed with aluminum and retains its colour.

UV resistance describes how well the coating is able to keep its original colour and gloss levels in accordance with EN10169. The higher the class, the better the resistance.

Corrosivity categories describe the outdoor climate conditions in accordance with EN12944. The higher the category, the more corrosive environment.
