Quiet warmth

Inspired by the warm and earthy tones of river clay, pebbles and stone, COLORBOND® steel in the colour Gully® is a grounded and calming colour. While mid-strength and subtle in tone, COLORBOND® steel Gully® is a versatile option for composite contemporary homes or more traditional homestead and ranch styles. Use COLORBOND® steel Gully® for roofing, walling, rainwater goods and garage doors to achieve a unified outcome that complements softer or limewashed bricks, natural stone and render coatings.
