For a high-performance, low-maintenance deck that stands up to the elements, the Trex Transcend Lineage Composite Deck is the choice for trade professionals and DIY enthusiasts alike at TJ O’Mahony. Combining the elegance of natural hardwood with the durability of composite, this grooved board makes deck installation faster, cleaner, and built to last.
Crafted from premium, capped composite material, the Trex Transcend Lineage boards resist fading, staining, scratches, and mold, giving you a beautiful finish year after year with minimal upkeep. The grooved edges are designed to work seamlessly with hidden fasteners, providing a smooth, professional-looking surface without visible screws or nails. Perfect for patios, gardens, pool decks, or commercial outdoor spaces, these boards are built to impress and endure.
Whether you’re laying a brand-new deck or upgrading an existing one, the Rainier grooved boards offer a long-lasting, weather-resistant solution that looks stunning in any outdoor setting.
Application: Decking boards for patios, gardens, pool decks, and commercial outdoor areas
TJ’s Tip:
Always use hidden fasteners for grooved boards to achieve a seamless surface, and leave a small expansion gap at each end for seasonal movement. Clean regularly with a soft brush and mild soapy water to keep your deck looking showroom-ready for years to come.
