Designed for clean lines and long-term performance, Trex Transcend® Lineage™ Composite Decking – is a premium decking solution for trade professionals and confident DIYers who want a flawless finish with minimal upkeep. Available from TJ O’Mahony, this high-quality composite board combines durability, modern style and reliable performance in all weather conditions.
Finished in Biscayne — a bright, coastal-inspired shade with subtle woodgrain detailing — it delivers a fresh, contemporary look that works equally well in new builds, renovations and garden upgrades. As part of the advanced Trex Transcend Lineage range, it features heat-mitigating technology engineered to help the board stay cooler underfoot in warmer weather.
The square edge profile makes it ideal for picture framing, stair treads and perimeter detailing, giving you flexibility in your deck design while maintaining a crisp, defined edge. At 4.88 metres long, it helps reduce butt joints across larger spans, keeping installation efficient and the finished result sharp and professional.
Built to resist fading, staining, rotting and splintering, this board eliminates the need for ongoing sanding, sealing or staining — just a simple clean to keep it looking its best year after year.
- Key Features:
- Biscayne Finish: Modern, light-toned colour with natural woodgrain effect.
- Square Edge Profile: Perfect for picture framing, edging and step applications.
- Low Maintenance: No staining, sealing or painting required.
- Durable Composite Construction: Resists rot, splintering, fading and weather damage.
- Heat-Mitigating Technology: Designed for improved underfoot comfort in sunny areas.
- 4.88M Board Length: Fewer joins and a cleaner overall layout.

TJ’s Tip:
Use square edge boards for borders and step finishes to frame your deck neatly and hide cut ends. Always follow the recommended joist centres and expansion gap guidelines to allow for movement. Taking the time to set out your first board perfectly straight will make the rest of the install run smooth and true.
