Linyi Rich New Materials Co., Ltd. stands as an authoritative modernized industrial enterprise and global trading powerhouse. Integrating advanced R&D, automated multi-line extrusion, precise CNC surface engineering, and global logistics optimization, we specialize in high-durability Wood-Plastic Composite (WPC) exterior paneling, structural facade cladding, and complete interior architectural surfacing systems.
Headquartered in Linyi City, Shandong Province—Asia’s central hub for new material production—our industrial complex operates under strict ISO9001, ISO14001, and CE certifications. By utilizing high-density polyethylene (HDPE) reinforced with purified micro-wood fiber matrices and proprietary thermo-stabilizing co-extrusion technology, we supply top-tier weatherable cladding to over 100 countries across North America, Europe, the Middle East, and Southeast Asia.
Our core mission centers on delivering uncompromising information gain, structural durability, and carbon-negative building envelope solutions for architectural engineers, commercial developers, and procurement executives worldwide.
Wood-Plastic Composite (WPC) exterior wall cladding represents a monumental leap in sustainable building envelope design. Unlike traditional timber cladding—which suffers from moisture absorption, rot, termite damage, and high maintenance costs—or pure PVC profiles that lack structural rigidity and natural aesthetics, co-extruded exterior WPC panels unite the mechanical tenacity of synthetic polymers with the organic tactile texture of natural timber.
Our exterior WPC cladding panels feature an outer structural shell made of modified fluorocarbon polymer and UV inhibitors. This impenetrable shield surrounds all four sides of the core, sealing out moisture, preventing micro-cracking, and shielding against severe weathering.
Formulated with high-grade carbon black, light stabilizers, and antioxidant compounds, our exterior panels withstand accelerated QUV testing exceeding 3,000 hours without significant color fading (Delta E < 2.0), ensuring 25+ years of exterior operational life.
Designed specifically for rainscreen curtain wall installations, the hollow-core multi-flute geometry creates a natural thermal cavity. This reduces building heat gain, increases acoustic dampening up to 28dB, and boosts thermal performance.

Exterior WPC panels combine wood fiber with high-density polymers, providing complete resistance to moisture, rot, termites, and fungal decay. Unlike natural timber, WPC requires no periodic staining, painting, or oil sealing. Furthermore, our 360-degree co-extrusion layer prevents UV degradation, color fading, and splintering, offering lower total cost of ownership over a 25-year lifespan.
Our panels are formulated with specialized linear thermal expansion stabilizers. Engineered for extreme climates spanning -40°C to +60°C (-40°F to 140°F), the expansion rate is kept below 3.5 × 10⁻⁵ /°C. By utilizing concealed clip fastener installation systems with proper expansion gaps, panels flex without buckling or gapping.
Our 100,000 m² modern production base operates over 120 automated WPC grating lines (12 million m²/year), 40 outdoor WPC wall panel/decking lines (2 million m²/year), 12 UV panel lines (6 million m²/year), 4 SPC flooring lines (3 million m²/year), and 6 PS/Carbon composite lines (1 million m²/year), guaranteeing stable lead times for major multi-container contracts.
Yes. Linyi Rich adheres strictly to zero-waste "Green Manufacturing" principles. Our WPC materials incorporate up to 90% recycled content (reclaimed wood fiber and post-industrial polymers). They are 100% recyclable, emit zero VOCs or formaldehyde, and help prevent deforestation by replacing natural hardwood cladding.
Absolutely. As a direct manufacturer, we offer full OEM/ODM customization. We match color samples to RAL/Pantone color systems and create custom 3D wood textures. Lengths can be cut precisely to your project specifications (e.g., 2.2m, 2.9m, 5.8m) to fit standard shipping containers while minimizing site cutting waste.
Exterior WPC cladding uses a ventilated rainscreen framework system. Aluminum or WPC joists (battens) are attached to the structural wall at 30-40cm centers. Starting from the bottom starter clip, panels interlock seamlessly via tongue-and-groove profiles or hidden stainless steel clips. This creates a concealed fastener finish that is fast to install.
Explore our comprehensive range of exterior cladding profiles, acoustic slat arrangements, SPC flooring finishes, soft stone veneers, and interior WPC wall systems in real-world settings.
Whether you are seeking custom-engineered co-extruded exterior WPC cladding, fire-rated acoustic wall panels, acoustic wood slat systems, or high-volume SPC flooring, Linyi Rich New Materials Co., Ltd. delivers certified engineering excellence, scalable capacity, and unbeatable factory-direct value.
