The YT-A40J25 WPC Solid Joist for Under Support is a high-strength foundation component designed to provide stable structural support for composite decking and other outdoor flooring systems. Measuring 40×25 mm, this joist combines advanced material technology with superior load-bearing capacity to ensure long-term performance and safety.
Manufactured from 35% recycled HDPE, 55% natural wood fiber, and 10% functional additives (including anti-UV, anti-oxidation, and reinforcing agents), the YT-A40J25 solid joist offers both sustainability and structural reliability. Its composite nature enables it to resist moisture, warping, and decay—making it an essential accessory for modern decking installations.
Product Advantages
1. Exceptional Structural Strength
The solid cross-section of the WPC joist provides excellent compressive and bending resistance, ensuring stability even under heavy loads. It serves as a reliable foundation layer for composite decks and terraces.
2. Superior Weather Resistance
Designed for all climates, the YT-A40J25 joist resists the effects of UV radiation, rain, frost, and temperature fluctuations. Unlike timber, it does not rot, crack, or deform, maintaining its strength through years of outdoor exposure.
3. Moisture and Corrosion Proof
Its closed-cell WPC structure prevents water penetration, protecting it from swelling and decay. It is also resistant to mold, mildew, and corrosion, making it suitable for humid or coastal regions.
4. Eco-Friendly Material Composition
Made with recycled HDPE and sustainably sourced wood fibers, the joist reduces environmental impact. It contains no harmful chemicals or heavy metals, aligning with modern green-building standards.
5. Low Maintenance and Long Lifespan
The product requires minimal care—no painting, sealing, or replacement due to rot. Under normal conditions, it provides reliable performance for over 15 years with minimal upkeep.
6. Easy Installation and Compatibility
The 40×25 mm design is lightweight yet sturdy, allowing quick and precise installation with standard fasteners. It can be used with most WPC decking systems, clips, and support structures for seamless assembly.
Product Uses
1. Decking Base Structure
Primarily used as a subframe under WPC decking, the solid joist distributes weight evenly and ensures a level, stable surface. It reduces stress on individual boards and improves the overall durability of the deck system.
2. Outdoor Flooring and Walkways
Suitable for patios, terraces, and boardwalks, this joist provides dependable support under composite or timber decking, ensuring long-term performance in high-traffic areas.
3. Commercial and Public Projects
Ideal for hotels, resorts, and recreational facilities where longevity and safety are key. It offers dependable strength without the maintenance demands of traditional wood joists.
4. Moisture-Prone Environments
Perfect for poolside decks, coastal installations, or humid landscapes, where conventional wood substructures would quickly degrade.
In professional decking systems, a strong base determines long-term performance. The YT-A40J25 WPC Solid Joist for Under Support ensures that every deck—whether residential or commercial—stands on a foundation built for strength, safety, and sustainability.
