Explore our premium range of factory-direct composite building elements, certified for international architectural developments.
Linyi Rich New Materials Co., Ltd. stands as a premier modernized industrial enterprise seamlessly integrating research & development, precision manufacturing, and international commerce. Dedicated to advancing eco-friendly composite building solutions, our corporate headquarters and manufacturing complex are strategically located in Linyi City, Shandong Province—China's primary hub for timber processing and composite technology.
Spanning an intelligent manufacturing base of over 100,000 square meters and powered by more than 300 senior engineering technicians, we spearhead innovation in WPC Tavan Borusu (Wood-Plastic Composite Ceiling Tubes/Baffles), architectural louvers, interior decorative paneling, and resilient flooring solutions. Our advanced extrusion systems ensure unmatched structural integrity, chemical stability, and aesthetic fidelity across high-density architectural applications.
An in-depth analysis of composite timber tube engineering, thermal performance metrics, and flame-retardant formulation.
WPC Tavan Borusu (Wood-Plastic Composite Ceiling Tubes/Pipes) represents a paradigm shift in modern commercial interior architecture and ceiling baffle engineering. Manufactured via high-pressure, thermal co-extrusion technology, these hollow and solid composite profiles merge the organic aesthetic warmth of natural timber with the extraordinary durability and dimensional stability of high-grade thermoplastics.
The matrix composition of our ceiling tube profiles relies on a carefully calibrated blend of 55% micro-milled bamboo/wood flour, 35% eco-friendly high-density polyethylene (HDPE) or PVC polymer matrix, and 10% non-toxic chemical additives—including ultraviolet stabilizers, lubricant processing aids, coupling agents (maleic anhydride grafted polyethylene), and halogen-free fire retardants.
Formulated without urea-formaldehyde resins, achieving European E0 and Japanese F4-Star air quality standards for safe indoor deployment.
Meets EN 13501-1 Class B-s1,d0 and ASTM E84 Class A flame spread indices, ensuring self-extinguishing behavior without toxic smoke emission.
Near-zero water absorption (<0.5%) prevents warping, rot, fungal decay, and termite infestation even in high-humidity tropical microclimates.
To assist structural engineers, commercial architects, and procurement managers in drafting tender documentation, the technical characteristics of Linyi Rich WPC Tavan Borusu are detailed below:
| Physical / Mechanical Property | Test Standard | WPC Tavan Borusu Value | Natural Timber Benchmark |
|---|---|---|---|

| Water Absorption (24 hr Immersion) | ASTM D570 | ≤ 0.45% | 15.0% – 35.0% |
| Flexural Modulus | ASTM D790 | ≥ 2,800 MPa | 1,200 – 1,800 MPa |
| Flame Spread Index | EN 13501-1 / ASTM E84 | Class B-s1,d0 / Class A | Class C or Non-rated |
| Thermal Expansion Coefficient | ASTM D696 | 3.5 × 10⁻⁵ /°C | Variable / Anisotropic |
| Formaldehyde Emission | EN 717-1 | ND (Not Detected - E0) | Emits natural VOCs / Resins |
| Acoustic NRC (with Insulation) | ISO 354 / ASTM C423 | NRC 0.65 – 0.85 | NRC 0.15 – 0.25 |
Unlike basic single-extrusion composite tubes on the market, Linyi Rich utilizes 360-degree co-extrusion technology. The inner structural core is encapsulated by an ultra-durable outer polymer shield enriched with concentrated UV blockers and anti-scratch additives. This prevents surface color fading (Delta E < 1.5 over 10 years) and guarantees long-term visual clarity in sunlit atrium installations.
Industrial scale engineered to support international commercial projects, massive wholesale distributors, and rapid turnarounds.
Our flagship extrusion workshop operates 120 continuous automated twin-screw extrusion lines dedicated to indoor WPC grating, ceiling tubes, and decorative baffles. Yielding an annual production output of approximately 12 million square meters, we eliminate production bottlenecks and accommodate sudden surge orders from global procurement contractors.
Equipped with heavy-duty calenders and online UV coating systems, our 4 specialized Stone Plastic Composite (SPC) lines deliver an annual capacity of 3 million square meters. Designed for high-traffic commercial spaces requiring total waterproof performance and extreme wear resistance (0.5mm/0.7mm wear layers).
Tailored for harsh exterior environments, 40 dedicated lines manufacture heavy-duty outdoor WPC wall cladding, exterior ceiling louvers, and co-extruded decking. Outputting 2 million square meters per year, these products withstand freeze-thaw cycles, desert UV exposure, and coastal salt spray.
Featuring 12 UV vacuum coating lines, 6 carbon fiber composite lines, and multi-axis CNC engraving machinery, we provide custom profile grooving, 3D wood grain embossing, wire brushing, and metallic thermal transfer foils according to bespoke architectural blueprints.
Versatile engineering deployments across transit hubs, commercial centers, corporate offices, and luxury hospitality projects.
WPC Tavan Borusu ceiling systems are extensively specified in airport terminals, railway concourses, and metro stations. Their lightweight structural design reduces ceiling dead loads, while linear tube spacing allows uninterrupted airflow, integrated HVAC diffuser installation, and concealed fire sprinkler integration.
In modern open-plan offices and retail shopping centers, controlling reverberation time is paramount. Suspended composite tube baffles break sound wave reflections. When paired with acoustic backing fleece, they achieve NRC acoustic ratings up to 0.80, elevating acoustic comfort without compromising open spatial design.
From hotel lobbies and restaurant dining rooms to covered outdoor porticos and terrace pergolas, co-extruded WPC ceiling tubes offer authentic wood grain aesthetics with complete protection against humidity, steam, atmospheric pollutants, and temperature swings.
End-to-end international fulfillment, rigorous quality control frameworks, and tailored OEM/ODM manufacturing partnerships.
Our production facilities strictly adhere to the ISO9001 Quality Management System and ISO14001 Environmental Management System. Every batch of WPC Tavan Borusu undergoes stringent laboratory evaluations prior to shipment:
Exporting to over 100 countries across Europe, North America, the Middle East, Southeast Asia, and Latin America, Linyi Rich understands the critical importance of transit protection and customs compliance:
Analyzing key technological shifts: Decarbonization, Circular Materials, and Smart Acoustic Engineering.
As global building regulations tighten around carbon footprint accounting and Embodied Carbon in Construction (EC3), the decorative materials industry is undergoing rapid technical evolution. Linyi Rich is at the forefront of three primary industry macro-trends:
Transitioning from virgin fossil polymers to 100% post-industrial recycled HDPE and bio-polyethylene derived from agricultural waste. This circular approach reduces product carbon intensity by up to 42% while retaining high tensile performance.
Integrating micro-perforation patterns directly into extruded WPC tube profiles during manufacture. This allows built-in acoustic absorption without visible surface holes, maintaining seamless wood aesthetics in auditoriums and lecture halls.
Replacing traditional screw-fastened ceiling assemblies with patented click-in aluminum carrier keels. Installation labor speeds are increased by 60%, drastically reducing contractor installation costs on mega-scale jobsites.
Direct answers for architectural specifiers, importers, general contractors, and procurement agents.
