Explore our high-performance exterior and interior composite building materials engineered for extreme weather durability and acoustic precision.
Global Industrial Scale, Advanced Material Engineering & Integrated Supply Chain Mastery
Linyi Rich New Materials Co., Ltd. stands as a premier modernized industrial and trading enterprise, seamlessly integrating advanced research & development, precision manufacturing, and international commerce. Dedicated to pioneering next-generation eco-friendly building materials, our corporate headquarters and centralized manufacturing complex are situated in Linyi City, Shandong Province—the logistical and industrial epicenter of East China composite materials.
Spanning an expansive 100,000 square meters of intelligent production space, our facility operates under rigorous international quality frameworks. Powered by a workforce exceeding 300 highly qualified engineers, material scientists, and senior technicians, we deliver engineered composite solutions that define durability, aesthetic realism, and structural longevity across more than 100 countries.
Advancing Composite Chemistry from 1st Generation Uncapped Profiles to 3.0 Co-Extrusion Fluoropolymer Shield Technologies
Our proprietary 360-degree acrylic-styrene-acrylonitrile (ASA) or modified high-density polyethylene (HDPE) protective outer shell encapsulates the core material completely. This prevents moisture ingress, sub-surface fungal spore colonization, and severe color degradation caused by high solar ultraviolet (UV) flux.
Incorporating nano-scale mineral micro-fillers and coupled coupling agents (Maleic Anhydride Grafted Polyethylene - MAPE), our WPC formulation reduces the linear thermal expansion coefficient down to <0.9%, eliminating warping, buckling, and joint shear stress in extreme seasonal thermal swings (-40°C to +60°C).
Engineered with non-toxic, halogen-free aluminum trihydrate (ATH) flame retardant complexes. Our custom commercial WPC wood decking achieves European Class Bfl-s1 fire rating certification, guaranteeing low smoke density and self-extinguishing flame propagation parameters.

Architectural Precision Tooling, Customizable Profiles, Density Control, and Bespoke Surface Texturing
Designed specifically for high-footfall public infrastructure, municipal boardwalks, marine docks, and luxury resort plazas. Solid profiles provide maximum mechanical flexural strength, high modulus of elasticity, and superior structural impact strength.
Optimized for residential terraces, balcony retrofits, roof decks, and private garden platforms. Featuring engineered internal tubular rib networks (square or round cavities), hollow profiles dramatically lower dead load weights while retaining high span stiffness.
While our core specialty centers on Custom Outdoor WPC Decking, Linyi Rich New Materials Co., Ltd. operates specialized industrial production wings across a broad architectural spectrum:
120 automated lines yielding 12M sqm/year. Ideal for architectural sunshades, interior screens, and decorative partitioning.
4 high-precision extrusion setups producing 3M sqm/year featuring 100% waterproof stone-plastic cores with click-lock joints.
40 specialized co-extrusion lines delivering weather-proof, moisture-sealed exterior facade cladding panels worldwide.
12 automated cleanroom coating lines outputting 6M sqm/year of lightweight high-gloss faux marble wall boards.
Integrated CNC engraving equipment combining sound-absorbing PET felt backings with architectural timber veneers.
High-durability decorative interior wall moldings, flexible stone veneers, and carbon-fiber composite panels over 200+ molds.
Global Engineering Implementations Across High-Traffic, Marine, Commercial & Residential Projects
Constant exposure to chlorine pool water, saltwater spray, and high humidity destabilizes timber decks. Linyi Rich custom WPC decks offer anti-microbial surfaces that prevent rot, salt crusting, and slip hazards around pool margins and overwater bungalows.
Urban public walkways require high load capacities, splinter-free safety for pedestrians, and zero annual sealing budgets. Our high-density solid composite boards are engineered to sustain heavy foot traffic, maintenance cart loads, and severe UV radiation without splitting.
Modern architectural deck retrofits require strict weight management and elevated pedestal support systems. Our hollow profile series delivers ultra-light structural load profiles integrated with hidden stainless steel clips for rapid rooftop assembly.
Adherence to International Testing Benchmarks, Environmental Directives & On-the-Ground Logistics Support
Building codes vary significantly across North America, Europe, Oceania, and the Middle East. Linyi Rich New Materials Co., Ltd. ensures that all manufactured WPC outdoor decks, wall panels, and SPC floors undergo third-party testing by leading institutions such as SGS, Intertek, and TÜV Rheinland.
To assist international building product distributors, project developers, and direct importers, we provide complete end-to-end service frameworks:
Automated Compounding, Real-Time Laser Measurement & Unmatched Capacity Scaling
Raw material formulation consistency is critical for long-term composite stability. Our centralized computer-controlled compounding system dispenses virgin HDPE resin, micro-milled wood flour, and chemical additives with sub-gram precision, guaranteeing uniform density across every batch.
Operating 120 automated WPC grating lines and 40 specialized outdoor decking lines, our extrusion facilities utilize multi-stage twin-screw extruders paired with online laser dimension scanners. This enforces strict dimensional tolerance limits (±0.2mm) on linear profiles.
By producing our own masterbatches, maintaining direct partnerships with recycled polymer reclaimers, and managing in-house mold creation, Linyi Rich shields clients from market raw material volatility, offering consistent year-round supply stability.
Streamlined Purchasing Workflows Designed for Building Supply Wholesalers, EPC Contractors, and Importers
Custom profile design, engineered load requirements, and surface texture matching.
Physical sample extrusion, color fastness testing, and mechanical strength validation.
High-speed parallel line production under ISO9001 QA monitoring protocols.
Custom pallet bundling, seaworthy moisture wrapping, and global freight handling.
Addressing Crucial Architectural, Engineering, and Purchasing Enquiries for Custom WPC Decking
Traditional 1st-generation composite boards are mono-extruded, leaving raw wood fibers exposed on the board surface to environmental moisture, UV light, and staining agents. Co-extruded 3.0 WPC features an engineered, non-porous fluoropolymer or modified HDPE outer shield that encapsulates the core 360 degrees. This capstock provides superior scratch resistance, complete stain protection (oil, wine, grease), zero color fading, and ultra-low water absorption (<0.3%).
Our custom outdoor WPC decking profiles carry a 25-year residential warranty and a 15-year heavy commercial warranty. Engineered to resist rot, fungal decay, termite infestation, and structural degradation, the actual operational lifespan of our co-extruded products often exceeds 30 years under normal environmental conditions.
Linyi Rich composite boards are formulated to maintain structural integrity across thermal ranges from -40°C (-40°F) up to +60°C (+140°F). Through thermal-stabilization additives and low-expansion core engineering, linear expansion is restricted to under 0.9%, preventing warping or gapping when installed with recommended clip spacing.
Yes. As a direct manufacturer operating an in-house tooling facility, we fabricate custom extrusion dies according to your exact CAD specifications. We offer customized length cutting (optimized for 20ft or 40ft container loading to minimize transport waste) and color matching services to match specific architectural color palettes (e.g., Teak, Walnut, Charcoal, Oak, Weathered Gray).
For standard residential applications using 23mm to 25mm profile thickness, maximum recommended joist center-to-center spacing is 350mm to 400mm (14" to 16"). For heavy commercial installations or high-load public walkways using solid profiles, we recommend joist spacing of 300mm (12") center-to-center.
Absolutely. Our products utilize up to 90% recycled content—comprising reclaimed post-industrial hardwood fibers and recycled high-density polyethylene polymers. By choosing WPC decking over natural timber, projects prevent deforestation while diverting plastic waste from oceans and landfills. All products are 100% recyclable at end-of-life.
Our standard MOQ for standard stock profiles is 500 square meters. For custom profile dies or non-standard custom colors, the MOQ is typically one 20-foot container (~800–1000 sqm). Lead times range from 15 to 20 days post-deposit and sample confirmation, backed by our 120+ active extrusion lines.
