Brown | Silver Grey Signature Range Decking Board
Bring the warmth of natural bushland tones to your outdoor space with the Brown & Silver Grey Signature composite decking board from THQ. This premium co-extrusion board pairs earthy brown with a cool silver grey — a versatile combination that complements Australian native gardens, timber homes, and contemporary Melbourne renovations. Whether you're building a new alfresco area in Geelong or refreshing a tired deck in the Yarra Valley, this board delivers the natural aesthetic of hardwood without any of the ongoing maintenance. Pickup available from four Melbourne-area warehouses, with delivery statewide.
Why Choose Composite Over Timber Decking in Victoria?
Hardwood timber decking in Victoria requires oiling every 12–18 months, is vulnerable to moisture, and will grey and splinter over time without constant upkeep. The Brown & Silver Grey Signature board eliminates all of that. The 4-sided polymer co-extrusion shell locks out moisture, resists staining and scratching, and holds its earthy colour through Melbourne's variable seasons and harsh summer sun — all backed by a 25-year structural warranty.
