Explore our high-precision engineered WPC panels, acoustic slats, and architectural cladding designed for seamlessly interlocking interior and exterior systems.
The modern architectural and building materials landscape is undergoing a systemic transition toward sustainable composite polymers and engineered modular cladding systems. Among these innovations, Interlocked Wood-Plastic Composite (WPC) panels have emerged as the premier benchmark for high-performance exterior and interior building envelopes. By integrating high-density thermoplastic matrices with refined cellulosic wood fibers via co-extrusion technology, China’s tier-one manufacturers have engineered a material class that effectively eliminates the structural vulnerabilities of traditional timber—such as rot, hygroscopic warping, termite attack, and flame vulnerability—while drastically lowering life-cycle carbon footprints.
As global regulatory bodies enforce stricter carbon reduction mandates (such as the EU Energy Performance of Buildings Directive and US LEED v4.1 certification standard), architectural specifiers, master builders, and commercial importers are increasingly turning to China Interlocked WPC Manufacturers & Suppliers. The technological advancement of maleic anhydride grafted polypropylene/polyethylene (MAPE/MAPP) coupling agents, combined with automated precision profile extrusion, allows interlocked WPC profiles to achieve tensile strength tolerances exceeding 25 MPa and water absorption rates under 0.5%.

| Joint Mechanical Interlock Shear | > 4.8 kN / m² | N/A (Nailed/Screwed) | N/A (Overlap Clip) | 1.5 kN / m² (Rivet) |
| Maintenance Cycle & Lifespan | 25+ Years (Zero Sealer) | 3-5 Years (Requires Staining) | 10-15 Years (Paint maintenance) | 15-20 Years (Coating degradation) |
Positioned at the epicenter of China's wood-polymer technological innovation, Linyi Rich New Materials Co., Ltd. represents the modern benchmark of industrial modernization, environmental stewardship, and integrated global trade. Headquartered in Linyi City, Shandong Province, the company operates an intelligent manufacturing footprint spanning over 100,000 square meters and powered by a dedicated workforce of over 300 highly skilled engineering technicians.
To cater to multi-faceted architectural demands across commercial real estate, luxury residential development, hospitality, and civic infrastructure, our plant houses eight specialized manufacturing divisions:
Housing 120 fully automated extruder lines with an annual throughput exceeding 12 million m². Integrates wood-like grain warmth with zero-maintenance polyolefin formulations.
4 high-precision extrusion suites delivering 3 million m² annually. Stone plastic composite core delivers 100% waterproof reliability and zero formaldehyde release.
40 customized co-extrusion production lines yielding 2 million m² per year, engineered specifically for severe thermal fluctuations, high UV indexing, and marine environments.
12 automated UV curing lines across clean-room workshops producing 6 million m² per annum of high-gloss, scratch-resistant stone-texture panels.

6 high-speed extrusion lines supported by over 200 precision master molds for lightweight, intricate 3D interior decorative wall profiles.
Proprietary bamboo charcoal micro-porous co-extrusion technology designed for indoor air purification, moisture control, and modern aesthetic wall covering.
The superiority of modern Interlocked WPC systems stems from micro-level material engineering. Unlike basic hollow profiles, interlocked WPC decking and wall panels engineered by Linyi Rich New Materials utilize a twin-screw co-extrusion architecture.
The exterior shell comprises an impenetrable fluoropolymer-modified HDPE resin sheath embedded with hindered amine light stabilizers (HALS). This capstock isolates the structural core from UV degradation, color fading (Delta E < 2.0 over 10 years), and chemical staining.
Designed with tight-tolerance tongue-and-groove click profiles, the interlock system creates a continuous hydro-phobic weather baffle. This mechanical joint eliminates visible screw heads, accommodates micro-thermal expansion, and resists wind-driven rain up to 120 Pa.
The interior core combines 60% reclaimed hardwood/bamboo flour, 30% recycled high-density polyethylene, and 10% active coupling additives. Micro-foaming technology reduces overall structural dead-weight while maintaining exceptional flexural modulus (> 2800 MPa).
Interlocked WPC products serve as versatile elements across modern master-planned developments, civic refurbishments, and industrial-scale projects.
Interlocked WPC cladding provides ventilated rainscreen capabilities that enhance building envelope thermal efficiency. By forming a continuous air cavity behind the interlocked boards, thermal bridging is minimized, reducing HVAC cooling loads in tropical and temperate climates.
Integrating sound-absorbing acoustic wood slat panels backed by high-density polyester fiber felt enables precise reverberation time management (NRC ratings up to 0.85). Ideal for corporate auditoriums, hotel lobbies, and educational environments.
Engineered interlocked decking systems withstand chlorine exposure, saltwater immersion, and high foot traffic without splintering. Hidden fastener clips combined with interlocked tongue grooves yield smooth, barefoot-friendly surfaces for boardwalks and pool decks.
For bathrooms, subterranean basements, and coastal residential spaces, specialized moisture-resistant WPC wall panels and UV marble sheets offer zero-mold propagation, effortless wipe-clean hygiene, and luxurious stone/wood finishes.
In addition to core interlocked WPC extrusions, Linyi Rich New Materials manufactures a complementary spectrum of eco-friendly architectural surfaces, including Soft Stone veneers, PS wall panels, SPC flooring, UV panels, and carbon fiber composites.
