RAL 7015
Slate Grey
RAL 7015 Slate Grey is a dark, blue-toned grey that faithfully replicates the color of natural roofing slate quarried across Wales, Spain, and Scandinavia. This refined shade is specified for metal roofing systems, premium facade panels, and contemporary residential design where a connection to traditional slate architecture is desired. Slate Grey provides a dignified, timeless appearance that ages gracefully and complements both traditional stone buildings and modern glass-and-steel structures.
