For long-lasting, low-maintenance decking that performs in all seasons, the Trex Enhance Composite Deck – Clam Shell Square Edge 140 × 25mm x 4.88 m length is a top choice for trade installers and DIY landscapers alike. Part of the proven Trex Enhance™ range, this square edge board pairs realistic wood grain aesthetics with the durability of composite materials — perfect for patios, garden decks, balconies and outdoor entertaining areas.
The soft, neutral Clam Shell finish offers a contemporary look that works seamlessly with modern builds or classic settings, giving your project timeless appeal without the ongoing upkeep of timber.
Key Features:
- Superior Composite Durability: Made from a high-performance blend of wood fibres and recycled polymer, this board resists rot, mould, splintering and moisture — keeping your deck looking great year after year.
- Square Edge Profile: Classic board edge that gives flexibility in installation — fix with surface screws for a clean, premium finish.
- Natural Wood Grain Look: Clam Shell’s soft, sandy-grey tones and detailed grain texture replicate timber aesthetics without fade-prone surfaces.
- Low Maintenance: No sanding, staining or sealing required — a simple soap-and-water wash is all you need for seasonal cleaning.
- Fade & Stain Resistant: Designed to handle UV exposure and everyday outdoor spills, preserving colour and performance in tough weather.

TJ’s Tip:
For best results, install on a firm, level joist structure with consistent joist spacing to aid ventilation and drainage — especially important in wet climates. Allow a small gap between boards for expansion and water run-off, and always use corrosion-resistant fixings.
