More Information

Give your deck a crisp, modern finish with Trex Transcend® Lineage Composite Decking. Designed for durability and a premium timber look, this board is perfect for trade professionals and confident DIYers. Available from TJ O’Mahony, it delivers the sleek appearance of timber without the ongoing maintenance.

Finished in Island Mist — a subtle, coastal-inspired grey with natural woodgrain detailing — it gives decks a contemporary, elegant look. Part of the high-performance Trex Transcend Lineage range, it’s engineered to resist rot, warping, splintering, fading, and staining, making it suitable for both domestic and commercial projects.

The square edge profile is perfect for picture framing, step treads, and perimeter detailing, giving your deck sharp, defined edges. At 4.88 metres long, it reduces joins and helps maintain straight lines for a professional, clean finish.

Made from durable composite material, there’s no need for sanding, sealing, or staining — just a simple wash down to keep it looking fresh.

Key Features:
- Island Mist Finish: Modern, soft grey with natural woodgrain effect.
- Square Edge Profile: Ideal for borders, steps, and precise edge detailing.
- Durable & Low Maintenance: Resistant to rot, warping, splintering, and fading.
- 4.88M Board Length: Fewer joins and a cleaner, continuous surface.
- Premium Composite Core: Built to withstand weather and heavy use.
