This hollow WPC decking adopts advanced co-extrusion molding technology with multi-cavity hollow internal structure. The hollow design effectively reduces the overall weight while retaining strong load-bearing capacity, cutting down transportation and installation costs for contractors. The surface features deep realistic wood grain embossing that perfectly imitates natural timber texture without regular maintenance such as painting, waxing or anti-insect treatment. The optimized composite formula delivers outstanding resistance against water rot, termite erosion, UV fading and extreme temperature changes, maintaining stable performance in all-year-round outdoor exposure. The interlocking side notch enables fast snap installation, significantly shortening on-site construction cycles.
The R&D team conducted rigorous anti-slip, freeze-thaw and salt spray aging tests to meet international outdoor building standards. Multiple wood-tone color options and customizable sizes are offered to support global bulk engineering orders.
To meet the rising demand for low-carbon sustainable building materials, THREE L WPC will expand its co-extrusion production capacity in Q4 2026. The brand will keep innovating durable, maintenance-free WPC products to replace traditional solid wood for worldwide outdoor landscape and construction projects.
