Direct factory-engineered composite decking, wall cladding, and acoustic systems manufactured for rigorous commercial and high-end residential applications.
The global outdoor building material sector has experienced a fundamental paradigm shift away from traditional timber and early-generation composite planks towards engineered, co-extruded Wood-Plastic Composite (WPC) decking systems. Commercial contractors, municipal urban planners, and international distributors increasingly reject pressure-treated pine, cedar, and tropical hardwoods due to rapid degradation, high maintenance overheads, rot, splintering, and heavy chemical leaching.
Modern architectural specifications demand materials capable of surviving environmental extremes—from arctic sub-zero freeze-thaw cycles to intense high-UV desert climates. Custom WPC decking manufactured by specialized OEM/ODM factories resolves these historical structural shortcomings. By encapsulating micro-milled wood fiber (lignocellulosic biomass) within a high-density polyethylene (HDPE) or polymer matrix, advanced co-extrusion technology delivers low-maintenance, dimensionally stable, and aesthetically authentic wood alternative solutions.

As an international pioneer in green building material manufacturing, Linyi Rich New Materials Co., Ltd. operates a modern, fully integrated manufacturing facility engineered to meet high-volume, precise technical specifications for commercial projects worldwide.
Headquartered in Linyi City, Shandong Province—China’s premier timber and eco-composite manufacturing hub—our intelligent production complex spans over 100,000 square meters. The plant integrates real-time gravimetric feeding systems, twin-screw co-extruders, automated inline surface embossing, and precise cooling channels to maintain structural dimensional tolerances within ±0.15mm.
Driven by 40 custom outdoor lines specifically equipped for multi-color co-extrusion, anti-aging additives, and weather-resistant polymer formulations.
120 fully automated high-speed extrusion units providing fine decorative louvers and acoustic wall grating profiles.
4 high-precision extrusion and lamination lines producing zero-formaldehyde click-lock vinyl flooring.
Includes 12 UV panel lines (6M sqm/yr) and 6 carbon fiber composite lines (1M sqm/yr) with custom CNC grooving equipment.
As a technical OEM/ODM factory, custom decking customization extends far beyond simple color choices. We engineer tailored material matrices, profile cross-sections, and cap-stock polymer shield chemistries to solve specific structural challenges faced by architectural projects.
Custom mold manufacturing for hollow circular profiles (lightweight, highly cost-effective), hollow square profiles, solid heavy-duty profiles (for high commercial foot traffic), and hidden-fastener groove systems. Custom board widths from 120mm to 200mm and thicknesses from 18mm to 35mm.
Formulation adjustments based on project environment: HDPE virgin/recycled matrix blend for flexible high-impact strength; PVC-based composite decking for superior flame retardancy (Class B1 / Class A flame spread ratings); and custom coupling agent addition (maleic anhydride grafted polyethylene) to boost tensile bonding strength.
Utilizing 2nd & 3rd generation co-extrusion technology, a protective fluorocarbon modified shield layer 360-degree encapsulates the inner core. This shield prevents water ingress, locks in surface anti-UV antioxidants, prevents scratch scarring, and resists stubborn oil, food, and wine stains.
Custom WPC decking must adapt to vastly different environmental stressors depending on geographic installation locations. Below are key engineered scenarios where custom decking formulations excel over standard off-the-shelf options:
Challenge: Constant exposure to salt spray, tidal submergence, high humidity, and intense sunlight causes rapid fastener corrosion, rot, and micro-cracking in timber.
Custom Solution: 360° capped co-extruded solid WPC planks paired with 316 stainless steel hidden clip systems. Zero moisture uptake prevents internal fiber swelling, while salt mist spray testing (ASTM B117) demonstrates 5,000+ hours with zero structural degradation.
Challenge: Water entering board pores freezes, expands, and causes internal delamination, cracking, and surface spalling during winter thaw cycles.
Custom Solution: Low-expansion HDPE wood composite formulation with <0.3% water absorption. Specially designed tubular hollow cavities maintain thermal flexural elasticity down to -40°C without brittle failure.
Challenge: Surface heat buildup exceeding 70°C, rapid UV bleaching of pigments, and board warping due to thermal expansion.
Custom Solution: Reflective inorganic ceramic color pigments incorporated into the outer cap layer reduce surface radiant heat by up to 12°C. Elevated Hindered Amine Light Stabilizers (HALS) ensure color retention grade > 4.5 after 3,000 hours of continuous UV-A exposure.
Challenge: Heavy public foot traffic, slip hazards around pool decks, strict commercial fire code requirements, and heavy maintenance downtime costs.
Custom Solution: R12 slip-rated deep 3D embossed grain surfaces combined with Class B1 fire-retardant additive formulations. Easy clean cap-layer allows high-pressure washing without damaging the surface texture.
