ModWood Marina Composite Decking Boards

Engineered for strength, stability, and harsh environments, ModWood Marina Board Composite Decking is a heavy-duty decking solution designed for marine, commercial, and high load applications. Proudly manufactured in Australia by ModWood, Marina Board delivers the natural timber look of the ModWood range with enhanced structural performance.

With a thicker 32mm profile, Marina Board provides increased stiffness and load capacity compared to standard decking boards, making it suitable for applications such as marinas, pontoons, boardwalks, and commercial decks. Manufactured using recycled plastic and reclaimed wood fibre, mMarina Board is splinter free, resistant to rot, moisture and termites, and requires no sanding, staining, oiling or painting, offering long-term durability with minimal maintenance in demanding environments.

• Low maintenance performance: No sanding, sealing, staining or painting required.

• Australian made and engineered: Proven durability in Australia’s tough climate conditions.
