Give your deck a natural, low-maintenance finish with Trex Enhance® Naturals Composite Decking. Designed for long-lasting performance and the look of authentic timber, this board is ideal for trade professionals and DIYers seeking a premium, durable deck. Available from TJ O’Mahony, it combines style, strength, and minimal upkeep.
Finished in Rocky Harbour — a rich, stone-grey tone with subtle woodgrain detailing — it delivers a contemporary, natural look that complements any garden, patio, or commercial outdoor space. Part of the high-quality Trex Enhance Naturals range, it’s engineered to resist rot, splintering, fading, and staining, ensuring your deck stays looking great in all weather conditions.
The square edge profile makes it perfect for perimeter detailing, picture framing, and step applications, giving your deck crisp, professional lines. At 4.88 metres long, it reduces joins for a smooth, continuous surface and speeds up installation.
With no need for sanding, sealing, or painting, this low-maintenance composite board retains its colour and durability with minimal effort.

  • Key Features:
    • Rocky Harbour Finish: Natural stone-grey with subtle woodgrain texture.
    • Square Edge Profile: Ideal for borders, steps, and precise detailing.
    • Durable & Low Maintenance: Resistant to rot, splintering, fading, and staining.
    • 4.88M Board Length: Fewer joins and a cleaner, continuous deck surface.
    • Timber-Look Aesthetic: Authentic appearance without the upkeep.
