Factory-direct composite solutions tested for extreme weather durability, acoustic mitigation, and zero-VOC interior performance.
Headquartered in Linyi City, Shandong Province, Linyi Rich New Materials Co., Ltd. operates a modernized 100,000 m² intelligent production ecosystem engineered for worldwide delivery.
Linyi Rich New Materials Co., Ltd. Enterprise Summary: Operating as a modernized industrial and trading leader, our factory seamlessly integrates R&D, structural formulation, precision extrusion, and global distribution. Utilizing 120 automated WPC grating lines (12 million m²/year capacity), 4 high-precision SPC flooring lines (3 million m²/year), 40 outdoor WPC wall panel/decking lines (2 million m²/year), 12 dust-free UV panel lines (6 million m²/year), 6 carbon fiber composite lines (1 million m²/year), and 6 PS wall panel lines with 200+ precision molds, we set the technical benchmark for China WPC suppliers.
The global architectural barrier and fencing sector has undergone a fundamental material migration over the past decade. Traditional materials such as wrought iron, unreinforced PVC, and raw timber face severe physical degradation when exposed to harsh ambient conditions. Wrought iron succumbs to oxidative corrosion and galvanic rust; raw timber suffers from hygroscopic expansion, fungal rot, termite infestation, and continuous maintenance cycles; unreinforced PVC lacks structural rigidity under elevated wind loads and suffers from UV-induced embrittlement. Modern structural engineering demands a high-performance alternative: Wood-Plastic Composite (WPC) Gates and Fencing Infrastructure.
China's manufacturing ecosystem, spearheaded by advanced facilities like Linyi Rich New Materials Co., Ltd., has led this global transition. By synthesizing refined lignocellulosic fibers (hardwood flour) with thermoplastics (High-Density Polyethylene - HDPE or Polyvinyl Chloride - PVC) through high-pressure co-extrusion technology, WPC gate and panel profiles offer an engineered strength-to-weight ratio superior to natural woods while remaining completely impervious to biological rot and moisture uptake.
Our 2nd and 3rd generation co-extrusion technology applies an outer layer of modified ASA (Acrylonitrile Styrene Acrylate) or fluorocarbon-enhanced polymers. This outer shield wraps 360 degrees around the dense inner WPC core, providing zero-water absorption (<0.5%) and high scratch resistance (Mohs hardness >4).
To satisfy industrial perimeter gate requirements and high-span automated driveway gates, our gate system profiles incorporate internal hollow-core channels specifically sized to accept structural hot-dip galvanized steel tubing (Q235 grade), enabling span widths exceeding 4.5 meters without sagging.
By incorporating nano-titanium dioxide UV blockers and localized antioxidant packages, our WPC gate profiles restrict color shift to ΔE < 2.0 under ASTM G154 accelerated weathering testing for 3,000 consecutive hours, preserving aesthetic richness across desert and maritime zones alike.

As a premier enterprise based in China's building materials epicenter, Linyi Rich New Materials Co., Ltd. serves over 100 countries across North America, Europe, the Middle East, Southeast Asia, and South America. Our production facilities maintain compliance with ISO9001, ISO14001, CE, ASTM, and REACH standards, ensuring that every linear meter of material shipped fulfills regional building code safety requirements.
Driven by 120 fully automated extrusion lines yielding 12 million square meters annually, our WPC gratings serve architectural sunshades, gate infill slats, facade cladding, and decorative screening. Available in fluted, semi-circular, and modular interlocking geometries.
Our 4 high-precision lines deliver 3 million square meters per year of Stone Plastic Composite flooring. Utilizing limestone polymer cores with IXPE acoustic underlayment, SPC delivers zero formaldehyde outgassing, 100% waterproof protection, and extreme heavy-footprint wear layers.
Engineered on 40 specialized heavy-duty extrusion lines (2 million m²/year), these heavy-gauge profiles withstand UV intensity, saltwater spray, snow loads, and severe thermal cycles (-40°C to +60°C) without delamination or structural deformation.
Our portfolio extends to high-end interior solutions: 12 UV Panel lines (6 million m²/year marble/gloss sheets), 6 Carbon Fiber composite lines (1 million m²/year grooved panels), Acoustic Slat Wood panels (PET felt backing), Bamboo Charcoal Wood Veneers, and Flexible Soft Stone.
From heavy commercial perimeter security gates to high-end residential patio fencing and sound-dampening interior acoustics, our engineered composite profiles integrate seamlessly into diverse architectural landscapes.
WPC gate slats are integrated into aluminum or steel structural frames to construct lightweight, low-inertia automated gates. Reduced frame weight extends the motor driver's operational lifespan while providing complete visual privacy and weather durability.
Designed with tongue-and-groove or modular post-and-rail channels, WPC fence panels provide wind-load resistance exceeding 120 km/h when anchored into concrete footings. Ideal for residential developments, resort perimeters, and industrial parks.
Combining PET polyester felt backings with fluted WPC or real-wood veneer slats, our acoustic wall panel series achieves Noise Reduction Coefficients (NRC) up to 0.85, making them essential for commercial auditoriums, hotel lobbies, and executive suites.
Linyi Rich New Materials Co., Ltd. continues to push the boundaries of polymer composite research through strategic industry-university-research partnerships. Our technical roadmap focuses on four primary pillars:
