The YT-A50J60 WPC Hollow Joist for Under Support is a high-strength structural component designed to provide a stable foundation for outdoor decking installations. As part of the WPC accessories series, it serves as the essential base framework that ensures even load distribution, prevents ground moisture intrusion, and extends the overall lifespan of the decking surface.
Manufactured from a composite blend of 55% natural wood fiber, 35% recycled HDPE (Grade A), and 10% advanced chemical additives—including UV stabilizers, colorants, and anti-fungal agents—the YT-A50J60 joist offers a perfect combination of rigidity, resilience, and environmental sustainability. With a 50x60mm profile and optimized hollow structure, it provides excellent balance between lightweight design and high load-bearing performance, making it ideal for both residential and commercial decking systems.
Product Advantages
1. High Structural Strength
Engineered for durability, the YT-A50J60 hollow joist can withstand significant static and dynamic loads without bending or deformation. Its structural integrity supports composite decking boards evenly, reducing the risk of sagging or uneven surfaces over time.
2. Weather and Moisture Resistance
Thanks to its co-extruded WPC composition, the joist resists moisture absorption, rotting, and corrosion. It performs reliably in humid, coastal, and rainy environments where traditional wood bases would decay quickly.
3. Environmentally Friendly Material
Produced from recycled HDPE and natural wood fiber, this joist contributes to sustainable construction practices by reducing plastic waste and reliance on virgin timber. The absence of harmful chemicals ensures a safer and more eco-conscious foundation solution.
4. Lightweight Yet Durable Design
The hollow structure minimizes material weight while maintaining structural stability. This makes transportation, handling, and installation easier, reducing overall project labor and cost.
5. Excellent Dimensional Stability
Unlike pure wood supports that expand, crack, or shrink under temperature and humidity variations, the WPC joist retains its original dimensions, ensuring long-term alignment and consistency across decking structures.
6. Low Maintenance Requirements
The smooth, non-porous surface of the WPC material resists dirt accumulation and microbial growth. It does not require painting, sealing, or chemical treatment, which reduces maintenance costs and time for installers and property owners alike.
Product Uses
1. Deck Substructure Support
Designed primarily for use beneath WPC decking boards, the YT-A50J60 provides a stable and long-lasting foundation that enhances decking performance and safety.
2. Outdoor Platform Construction
Ideal for balconies, patios, pool decks, and terrace flooring, the joist system supports uniform load distribution, preventing structural distortion under heavy foot traffic or furniture.
3. Raised Flooring Systems
Suitable for installations over uneven ground or where water drainage is required, the joist can be used with adjustable pedestals or spacers to achieve desired height and level adjustments.
4. Landscape and Garden Projects
The WPC joist’s durability and resistance to moisture make it ideal for pergola bases, outdoor seating structures, and other garden architectural frameworks that require stable, rot-proof support.
For designers, contractors, and homeowners seeking a reliable, sustainable, and high-performance decking base solution, the YT-A50J60 WPC Hollow Joist for Under Support is a smart and forward-looking choice.
