Solid and sophisticated

Inspired by the mineral tones and tactile qualities of the ancient rock it represents, Basalt® is a deep and robust grey. It is an adaptable colour that creates a striking interplay between materials through its subtle finish. When COLORBOND® steel Basalt® in a Matt finish is used for roofing, walling, gutters and fascia applications, it coordinates with greyed timbers and unpolished concrete to form a solid and sophisticated scheme, while contrasting with recycled bricks and crisp white accessories when used on inner-city, suburban and rural housing applications.
