PRODUCT DESCRIPTION

The Terra Deck Walnut is a Co-Extrusion Gen 5 WPC decking board engineered specifically for Australian outdoor conditions. Measuring 138mm wide, 23mm thick, and 5400mm long, each board features a circular hollow core design that keeps weight down while maintaining excellent structural strength.

The Gen 5 co-extrusion process wraps a protective polymer shell around the composite core on all four sides. This matters in practice — it means the board resists moisture penetration, surface staining, and UV-related colour shift far better than first or second-generation WPC. Melbourne’s unpredictable weather throws a lot at outdoor materials: scorching summer days, frosty winter mornings, and everything in between. These boards are built for exactly that.

Q: What is WPC decking and how is it different from timber?
A: WPC stands for Wood Plastic Composite — a blend of wood fibre and recycled plastic polymer. Unlike natural timber, WPC boards don't need oiling, sanding, or staining, and they won't rot, warp, or attract termites. The look is similar to real wood, but the upkeep is a fraction of the work.
Q: What does "Gen 5 co-extrusion" mean on the Terra Deck boards?
A: Gen 5 refers to the fifth generation of WPC manufacturing technology. Co-extrusion means the board is manufactured with a solid polymer shell bonded to all four sides of the composite core during production. This cap layer is what gives the board its stain resistance, UV colour stability, and moisture protection — it's a meaningful upgrade over earlier-generation WPC boards that had no outer capping.
