Explore our top-tier precision-extruded WPC wall claddings, acoustic slat systems, and high-durability composite panel series designed for global commercial and residential developments.
Linyi Rich New Materials Co., Ltd. is a professional modernized industrial and trading enterprise integrating research & development, industrial polymer formulation, automated extrusion manufacturing, and international trade. Headquartered in Linyi City, Shandong Province—the largest wood processing and logistical hub in China—the enterprise operates an intelligent manufacturing plant spanning over 100,000 square meters staffed by over 300 professional technicians and materials engineers.
By integrating closed-loop supply chains with high-precision double-screw extrusion lines, Linyi Rich delivers sustainable, zero-formaldehyde, fire-retardant, and weather-resistant interior and exterior cladding systems to architects, global wholesalers, and contract engineering firms in more than 100 countries.
Understanding the transition from traditional timber facades to high-density 3rd-generation co-extrusion polymer wall systems in architectural procurement.
WPC wall panels are manufactured by homogenizing ultra-fine hardwood flour (60%) with refined thermoplastics such as High-Density Polyethylene (HDPE) or Polyvinyl Chloride (PVC) (30%), coupled with 10% chemical additives including coupling agents, UV stabilizers, anti-oxidants, and micro-pigments. This matrix eliminates wood's organic vulnerabilities to moisture expansion and termite decay while maintaining natural tactile aesthetics.
Modern exterior and high-moisture indoor WPC panels feature a secondary engineered outer shell co-extruded simultaneously over the inner composite core. This outer layer consists of advanced fluorocarbon or modified acrylic polymers that deliver near-zero water absorption (<0.5%), extreme scratch resistance, and immunity to color fading caused by severe UV radiation (UV Index 10+ environments).
Unlike pressure-treated timber containing toxic chromated copper arsenate (CCA) or chemical varnishes, Chinese WPC products engineered by Linyi Rich prioritize circular sustainability. 100% of scrap WPC generated during processing is recycled back into the extruder line without degrading mechanical strength, fulfilling global BREEAM and LEED green building certification standards.
Linyi Rich New Materials operates high-capacity, multi-line automated production infrastructure engineered for bulk procurement consistency and rapid global dispatch.
Operating 120 fully automated production lines with an annual capacity of approximately 12 million square meters. Combines authentic tactile wood aesthetics with lightweight hollow structures for fast interior partition and feature-wall assembly.

China manufactures over 70% of the world's wood plastic composite building products. Linyi City stands as the core epicenter of raw material aggregation and engineering scalability.
Linyi's industrial ecosystem provides direct, zero-transit access to premium wood fibers, PVC polymers, calcium carbonate fillers, and specialty foils. This proximity reduces raw material procurement costs by 15-20% compared to isolated manufacturers.
With over 200 custom extrusion die molds already engineered (ranging from half-round fluted, 3D Great Wall wave profiles, to inter-locking tongue-and-groove boards), importers save thousands in tooling fees and accelerate project lead times.
Integrated direct rail and port access (Qingdao Port) combined with standardized palletized packing ensures fast container turnarounds (14-21 days order-to-shipment) with minimal risk of edge chipping during oceanic freight.
From luxury hospitality lobbys to heavy-traffic commercial facades and moisture-prone bathrooms, WPC materials replace traditional drywall, ceramic tile, and real timber.
Modern hotels, office lobbies, and retail boutiques utilize vertical fluted WPC Grating Panels and UV Marble Sheets to construct high-impact accent walls. The interlocking click-lock joint hides screw fasteners, providing seamless continuity while shielding interior partition walls from heavy luggage and cart impacts.
Designed for severe ambient fluctuations, co-extruded outdoor WPC panels serve as rain-screen curtain wall claddings and patio decking. Absorbing less than 0.5% water, they eliminate rotting, fungal spore growth, and the annual chemical staining required by natural cedar or teak decks.
Open-plan corporate spaces, recording studios, and lecture halls utilize Acoustic Slat Wood Panels. Combining precision CNC-milled wooden slats with high-density polyester fiber backing dampens mid-to-high frequency acoustic echoes, improving speech clarity without sacrificing natural wood design aesthetics.
Bathrooms, kitchens, and basements suffer from mold proliferation on traditional drywall or timber. Bamboo Charcoal Wood Veneer and PVC Ceiling Panels offer non-porous, waterproof, anti-bacterial surfaces that can be wiped clean with neutral detergents while releasing zero formaldehyde VOCs.
Answers to common structural, environmental, and global distribution questions raised by architects, OEM buyers, and importers.
Indoor WPC wall panels prioritize decorative versatility, lightweight profiles (often PVC-based), zero-formaldehyde indoor air quality ratings (E0 standard), and acoustic insulation. Outdoor WPC claddings utilize heavy-duty HDPE polymer matrices blended with recycled wood flour, featuring thick-walled hollow or solid extrusions protected by a 360-degree co-extruded shield engineered for extreme thermal shifts, intense UV light exposure, and sub-zero moisture expansion resistance.
Linyi Rich WPC wall panels achieve Class B-s1, d0 fire retardancy ratings under European EN 13501-1 testing standards and UL 94 V-0 requirements. When exposed to flame, the material self-extinguishes within seconds without generating flaming droplets, making it fully compliant for high-occupancy commercial structures, hotel corridors, and educational institutions.
Yes. One of the main cost benefits of WPC Great Wall panels and grating systems is their ability to span uneven substrates. On level indoor walls, panels can be bonded directly using structural polyurethane adhesive. On raw masonry or uneven exterior surfaces, panels are fastened onto lightweight aluminum or WPC furring battens using hidden stainless-steel starter clips, creating a ventilated air gap that prevents moisture accumulation.
As a direct factory supplier with over 120 production lines, Linyi Rich provides comprehensive OEM/ODM customization. This includes custom extrusion profile dimensions, specific wood grain foil hot-stamping, matte/high-gloss UV surface coatings, fire-retardant additive ratios, pre-cut length optimization (to fit 20ft or 40ft HQ containers perfectly), and private-label protective film packaging.
UV Marble Sheets provide the luxury aesthetic of natural marble at approximately 10-15% of the material and labor cost. They are lightweight (approx. 6 kg per full 1220x2440mm sheet versus 60+ kg for natural stone), require no heavy structural wall reinforcement, can be cut with standard utility knives or woodworking saws, and feature a non-porous UV shield that will not stain from acidic liquids or coffee spills.
