RAL 8004

Copper Brown

RAL 8004 Copper Brown is a warm, metallic-inspired brown that closely replicates the color of weathered Corten steel and aged copper surfaces. This industrial-chic shade has surged in popularity alongside the architectural trend for oxidized metal aesthetics. Copper Brown is specified for facade systems, feature walls, and architectural elements where the look of naturally weathered steel is desired without the ongoing oxidation process. It pairs dramatically with raw concrete, black steel, and warm timber.
