The YT-A40J30A WPC Solid Joist for Under Support is a core structural element designed to provide a stable and durable foundation for WPC decking and other outdoor flooring systems. Measuring 40x30mm, this joist combines advanced co-extrusion WPC technology with reinforced material composition to ensure long-term load-bearing strength and resistance to environmental challenges.
Manufactured using a balanced blend of 55% natural wood fiber, 35% recycled HDPE, and 10% performance-enhancing additives, the joist delivers exceptional stability, dimensional consistency, and weather endurance. As a critical part of any decking installation, this solid WPC joist guarantees both functionality and structural integrity, ensuring that your outdoor flooring remains level, secure, and long-lasting.
Product Advantages
1. Superior Structural Strength
The solid core design provides excellent load-bearing capacity, ensuring reliable support for WPC decking systems even under heavy foot traffic or furniture weight. It resists bending, cracking, and deformation over time.
2. Moisture and Rot Resistance
Unlike traditional wood joists, the WPC Solid Joist is non-porous and does not absorb water. This prevents swelling, rotting, or mold formation—making it ideal for damp or coastal environments.
3. UV and Weather Protection
The inclusion of anti-UV and anti-oxidation agents in the material formulation enhances outdoor performance. The joist withstands sunlight exposure, rain, and temperature changes without fading or structural deterioration.
4. Environmentally Friendly Composition
Made from recycled HDPE and natural wood fibers, the product minimizes environmental impact while delivering exceptional performance. It is free from harmful substances and fully recyclable after use.
5. Low Maintenance
No painting, sealing, or oiling is required. The joist retains its stability and strength with minimal upkeep, saving time and maintenance costs throughout its service life.
6. Long-Term Durability
With proper installation and load distribution, the YT-A40J30A joist can last well over a decade, maintaining its structural reliability and appearance in various climates.
Product Uses
1. Decking Substructure Support
Designed primarily as the under-structure for composite or WPC decking systems, providing a firm and evenly distributed base for planks and tiles.
2. Outdoor Platforms and Walkways
Suitable for use beneath raised outdoor flooring, terraces, garden paths, or balconies that require moisture-resistant and stable support.
3. Commercial and Residential Applications
Ideal for patios, pool decks, rooftop gardens, and public boardwalks where high durability and minimal maintenance are essential.
4. Replacement for Wooden Joists
A sustainable alternative to timber joists that eliminates issues like decay, termites, and frequent replacement—making it perfect for long-term installations.
In addition to functional performance, the product also contributes to sustainability goals. By combining recycled HDPE and reclaimed wood fiber, the YT-A40J30A reduces dependence on virgin resources and helps minimize plastic waste in the environment.
When used as part of a complete WPC decking system, the joist enhances both performance and design flexibility. It ensures a stable and level foundation that supports uniform spacing, prevents water accumulation beneath the deck, and improves air circulation—extending the lifespan of the entire outdoor flooring structure.
In summary, the YT-A40J30A WPC Solid Joist for Under Support represents a perfect combination of engineering precision, material innovation, and environmental responsibility. It is the foundation for any high-quality outdoor decking system, ensuring safety, longevity, and sustainability for years to come.
