Trex Beach Dune Composite Decking 20ft Solid

Trex Beach Dune Composite Decking 20ft Solid Board is an excellent choice for those seeking a long-lasting, low-maintenance deck with a warm, natural wood-like appearance. The “Beach Dune” colour delivers a soft sandy-brown tone with a realistic wood-grain composite texture, neutral and versatile, able to integrate seamlessly with a variety of exterior styles, from coastal-inspired to classic suburban homes.

Because it’s part of Trex’s Enhance Basics (composite) line, this board offers durability, eco-friendly materials, and minimal upkeep, delivering the look of wood without the drawbacks.

Key Features & Benefits

• 20 ft nominal length — ideal for large decks, waterfront patios, or any build needing long, continuous runs with fewer seams.
• Solid-edge profile — well suited for traditional fastening with colour-matched screws, making it a good fit for borders, stair edges, trim pieces, or picture-frame perimeters.
• Beach Dune colour and wood-grain finish — a soft sandy-brown hue with natural composite grain texture that complements siding, stone, railings, and landscaping.
• Composite construction (≈ 95% recycled materials) — provides water-resistance, rot and mold resistance, and avoids warping, splitting, or splintering common to natural wood.
• Protective shell cap — helps guard against fading, stains, scratching, mold, and mildew; ensures long-term wear resistance and preserves colour and texture.
• Low maintenance — no need for sanding, sealing, or painting; periodic cleaning with mild soap and water is sufficient to keep the deck looking fresh.
• Sustainable & eco-friendly — made largely with recycled materials, reducing environmental impact compared to traditional lumber.
• Backed by warranty — covered under Trex’s 25-Year Limited Residential + Fade & Stain Warranty, offering long-term protection and peace of mind.
