Overview
The reasoning behind the spec.
Our WPC Hollow Decking is engineered to win every comparison call. At 150mm wide it covers roughly 9% more area per board than the standard 137mm retail profile, and at $48 wholesale per 5400mm board it lands at nearly half typical retail pricing. The core is new virgin composite, not recycled off-cuts, for consistent density throughout, and the 0.8mm UV-stabilised outer layer is a true commercial specification that holds colour for years rather than seasons. Fully waterproof, fully fireproof, and stocked in five exterior-ready colours.
What sets it apart
Engineered details.
150mm board width
Wider than the standard 137mm retail profile, fewer boards per square metre, faster installation, lower total material cost.
0.8mm UV layer
Commercial-grade UV-stabilised outer layer. Budget brands run 0.2-0.3mm and fade in 1-2 Australian seasons.
New virgin composite
Consistent density throughout the board, not recycled off-cuts. No soft spots, no inconsistent fade.
Waterproof and fireproof
Suitable for pool surrounds, alfresco areas and exposed coastal decks without bushfire compliance burden for decorative use.

The comparison
How WPC Hollow Decking measures up.
A direct, like-for-like specification read against the typical alternatives on the Australian market.
Teak & Rope
Specification- 150mm board width, covers more area per board
- 0.8mm UV-stabilised outer layer, commercial grade
- New virgin composite, consistent density throughout
- $48 per 5400mm board, wholesale pricing
- Fully waterproof and fireproof
- 5 colours: Silver Grey, Smoke Grey, Dark Grey, Mahogany, Walnut
Typical alternatives
Market- 137mm wide, around 9% narrower per board
- Retail pricing up to 47% more expensive per board
- Recycled-material cores, inconsistent density and faster fade
- 0.3mm UV coating, entry level, fades in 1 to 2 seasons
- Confirmed colour loss from UV in full Australian sun
- Many require additional hardware sourced separately
Why it matters
At 150mm versus 137mm you need approximately 9% fewer boards to cover the same deck, before the per-board price difference even comes into it.
