This 148.5*22.5mm WPC decking board innovatively combines a 7-round-hole framework with a full co-extrusion capping process, engineered specifically to withstand extreme outdoor climates. The 7-hole structure not only provides excellent bending toughness but also efficiently absorbs external impacts, ensuring the deck remains deformation-free under long-term foot traffic. Its true core highlight lies in the polymer co-extruded protective layer. This 360° dense armor completely isolates the WPC core from the outside world, fundamentally preventing moisture penetration and UV erosion. Even on high-salinity coastal boardwalks or sun-baked poolside areas, it guarantees no fading or molding. With minimal maintenance costs, it offers a versatile paving solution that combines long-lasting weather resistance with 3D wood grain aesthetics for high-end projects.
