This 20mm hollow core, 160mm unified width co-extruded WPC fence slat is a top pick among landscape designers and engineering contractors. The integrated co-extrusion craft forms a dense protective coating that withstands extreme temperature shifts and damp coastal climates. Its 160mm wide design reduces joint lines to build elegant, seamless privacy barriers with authentic natural wood texture. Free from splinters, rot and color fading, it saves long-term maintenance costs. Made of recycled wood and plastic materials, it serves as a sustainable substitute for solid wood fencing, widely applied in villa perimeter fences, terrace privacy screens, hotel garden enclosures and public landscape separation walls.
