The 160*19mm 1st Gen Fluted Hollow Composite Fence Panel is a high-performance extruded profile engineered for modern residential garden boundaries, commercial perimeter barriers, and outdoor privacy screens. Manufactured using classic 1st Generation high-temperature twin-screw continuous extrusion technology, it blends 60% refined wood flour, 30% modified high-density polyethylene (HDPE), and 10% eco-friendly functional additives including UV stabilizers and anti-mold agents. Featuring a unique 3-slat fluted 3D design and 160mm * 19mm engineering profile, this panel showcases a natural, embossed wood-grain surface. Its multi-chamber hollow internal structure significantly reduces overall board weight while maintaining exceptional wind resistance and flexural rigidity. Designed with precision side tongue-and-groove interlocking slots, it ensures seamless concealed assembly, completely resolving traditional timber vulnerabilities such as rotting, warping, molding, termite damage, and frequent painting maintenance.
Technical Q&A: Contractor & Importer FAQ
Q1: How do the Fluted surface design and Hollow core structure enhance the performance of the 160*19mm 1st Gen Fluted Hollow Composite Fence Panel?
The 3-slat fluted design increases the section modulus of the board, boosting flexural rigidity under lateral load. Simultaneously, the multi-chamber hollow geometry reduces the unit weight per meter by over 25%, drastically lowering dead weight on support posts. Under heavy outdoor wind loads, this engineered shape delivers superior wind pressure safety while offering a refined, modern 3D visual aesthetic.
Q2: How does a 1st Generation (1st Gen) WPC fence board ensure long-term UV and weather resistance outdoors?
Although 1st Gen WPC does not feature an outer co-extruded cap, the 160*19mm 1st Gen Fluted Hollow Composite Fence Panel incorporates hindered amine light stabilizers (HALS) and high-weatherability inorganic mineral pigments directly into the raw compound. High-density HDPE polymers micro-encapsulate every wood fiber, ensuring that after an initial 3 to 6-month natural weathering stabilization period, the panel enters a long-term color plateau without chalking, peeling, or fading.
Q3: What joist/post spacing and thermal expansion rules should be followed during installation?
To ensure wind resistance and panel alignment, aluminum or steel support posts should be fixed at a maximum center-to-center spacing of 1.2m to 1.5m. Because the panel experiences minor thermal expansion and contraction, installers should leave a 3mm to 5mm expansion gap inside the vertical post channels or at panel ends to prevent buckling during hot summer temperatures.
Q4: What are the shipping and loading advantages of the 160*19mm 1st Gen Fluted Hollow Composite Fence Panel for overseas B2B importers?
The flat, standardized 160mm * 19mm hollow profile allows panels to be compactly stacked and strapped on export pallets. The lightweight hollow core prevents container weight overloads, enabling importers to maximize both volume and weight capacity inside a 40'HQ container. This significantly lowers per-square-meter sea freight and landed costs.
