How to choose the right Composite Decking
Start with the look and the budget. For a cost-effective deck with a natural timber look, entry-level boards deliver low maintenance at a lower price. For a premium finish, choose fully capped boards in contemporary colours, which add a protective outer layer against fading, staining and scratching.
For coastal homes or a weathered, rustic timber look, wide boards with a weathered finish and fully capped protection are designed to stand up to moisture and salt air. For commercial and high-traffic areas, choose a solid, fully capped board and talk to us about joist spacing before you order.
Our composite decking ranges are rated to BAL 29, but compliance depends on the installation system and your site’s assessed BAL, so confirm the requirements with your certifier. Compare the options on the product cards above, or talk to the Big River team for help matching a board to your project.
Why choose Composite Decking?
Where is Composite Decking used?
Composite decking suits a wide range of outdoor projects. In residential building it is commonly used for alfresco areas, patios, pool surrounds and renovations where owners want a timber look with minimal upkeep. Coastal homes benefit from boards that resist moisture and salt exposure.
In commercial and public settings, composite decking is used for boardwalks, cafe and venue terraces, and other high-traffic areas where durability and low maintenance reduce long-term costs.
Composite Decking vs Other Materials
Composite decking is the lowest-maintenance way to get a timber look. Compared with natural hardwood, it removes the need for regular oiling and sealing and is less prone to cracking and fading. Compared with fibre cement decking, it offers a warmer, more timber-like appearance, while fibre cement is the choice for the highest bushfire ratings (BAL-FZ).

Frequently Asked Questions
What is composite decking?
Composite decking is made from a blend of timber fibre and polymer, often using recycled materials. It looks like timber but is designed to resist the warping, cracking, fading and staining that affect natural decking.
Does composite decking need sealing or oiling?
No. Composite decking does not need sanding, staining or sealing. A regular clean is all that’s needed to keep it looking its best.
Is composite decking suitable for bushfire-prone areas?
Our composite decking is rated to BAL 29. Your site’s required BAL and the installation system both affect compliance, so check with your certifier. For the highest ratings, see our fibre cement decking, which is rated to BAL-FZ.
Can composite decking be used near the coast?
Yes. Composite decking resists moisture, and fully capped boards with a weathered timber look are designed for beachside homes and other coastal spaces.
What's the difference between capped and uncapped composite decking?
Capped boards have a protective outer layer over the composite core, which helps resist fading, staining and scratching. Uncapped boards are usually more affordable but offer less surface protection.
