THREE L WPC, a professional manufacturer of wood plastic composite building materials, has officially released its new generation hollow WPC profiles, covering hollow deck boards, interior wall cladding panels and special structural WPC frames to serve global outdoor landscape and architectural decoration markets.
The upgraded hollow WPC boards adopt optimized wood-plastic co-extrusion technology with multi-hole hollow internal structures. This design effectively reduces product weight while retaining high structural strength, delivering outstanding load-bearing capacity and thermal insulation performance. The textured embossed surface provides anti-slip function, perfectly suitable for outdoor terraces, garden walkways and balcony flooring. The matching interlocking wall panels feature a seamless snap installation system, cutting construction time by nearly 40% for residential and commercial interior decoration.
All products are engineered to resist water, rot, termites and UV fading, eliminating the regular painting and maintenance required for solid timber. The factory’s R&D team completed 6-month durability tests including salt spray, freeze-thaw and long-term outdoor exposure to meet international construction standards. Available in classic brown and charcoal black color options, these WPC profiles support bulk orders for landscaping contractors, construction wholesalers and overseas engineering projects.
To satisfy growing global demand for eco-friendly building materials, THREE L WPC will upgrade its co-extrusion production lines in Q4 2026. Committed to sustainable composite solutions, the brand will keep innovating low-carbon WPC products to replace traditional natural wood for worldwide outdoor construction.
