Explore our primary series of co-extruded WPC letve profiles, UV composite marbles, acoustic slat wood systems, and heavy-duty outdoor cladding solutions engineered for global commercial and luxury residential projects.
Linyi Rich New Materials Co., Ltd. is a modernized industrial and trading enterprise integrating advanced material science research & development, automated extrusion manufacturing, and global supply chain logistics. Headquartered in Linyi City, Shandong Province—the primary hardware and building materials manufacturing hub of East China—our enterprise operates an intelligent manufacturing footprint spanning over 100,000 square meters.
With an engineering headcount exceeding 300 professional technicians, chemical engineers, and QA auditor specialists, we lead the industry in producing structural Wood-Plastic Composite (WPC) Letve profiles, fluted wall louvers, SPC flooring matrices, acoustic wood slats, and UV-cured decorative panels. Our production facility operates in strict accordance with the ISO9001 Quality Management System and ISO14001 Environmental Management Framework, delivering fully certified architectural elements to global markets across Europe, North America, the Middle East, and Southeast Asia.
Terminologically referred to across Northern European and global architectural markets as WPC Letve ( composite laths, slatted profiles, fluted panels, or linear architectural louvers ), these components represent a paradigm shift in exterior facade envelope design and interior acoustic surface treatments. Unlike traditional timber laths that suffer from hygrothermal deformation, rot, insect damage, and rapid UV degradation, custom engineered WPC Letve integrates high-density thermoplastic matrices with micro-encapsulated wood flour.
| Technical Property / Benchmark | Standard Test Method | Custom WPC Letve Metric | Engineering Benefit |
|---|---|---|---|
| Density & Specific Gravity | ASTM D792 / ISO 1183 | 1.35 – 1.45 g/cm³ | High structural rigidity, impact strength, and structural dimensional stability. |
| Flexural Modulus (Rigidity) | EN ISO 178 / ASTM D790 | ≥ 2800 MPa | Prevents sagging under heavy wind loads or vertical span installations. |
| Fire Retardancy Rating | EN 13501-1 / ASTM E84 | B-s1, d0 Class (Flame Retardant) | Self-extinguishing, low smoke density, zero toxic flaming droplets. |
| Linear Thermal Expansion Rate | ISO 11359-2 | < 3.5 × 10⁻⁵ /K | Controlled expansion gaps in extreme temperature differentials (-40°C to +60°C). |
| Water Absorption (24h immersion) | ASTM D570 / EN 317 | ≤ 0.5% (Impermeable) | Zero rot, zero swelling, complete immunity to fungal growth. |
| UV Weathering Accelerated Aging | ISO 4892-2 (3000 Hours) | Grey Scale ≥ 4 (Delta E < 2.0) | Long-term color fastness via ASA/PMMA co-extruded protective shield. |
Our advanced 360-degree co-extrusion technology seals the internal WPC core with an acrylic fluorocarbon protective outer armor. This shield resists oil stains, severe UV degradation, acid rain, and mechanical scratch wear.
We maintain an in-house precision CNC mold manufacturing shop capable of producing custom letve cross-sections, hollow multi-cavity weight-reducing profiles, solid structural battens, and interlocking architectural tongue-and-groove joints.
Utilizing 60% ultra-fine wood micro-fibers mixed with 30% recycled high-density polyethylene (HDPE) or PVC, our formulations minimize reliance on virgin polymers while maximizing eco-friendly tensile strength.
The competitive landscape of international building material procurement requires high capacity, chemical purity control, fast batch lead times, and aggressive unit cost efficiencies. Linyi Rich New Materials provides unparalleled scale.
Operating 120 fully automated extrusion lines for WPC Letve/Grating alongside 40 customized outdoor profile lines and 12 UV coating lines, our daily throughput exceeds 35,000 square meters. Standard 40ft high-cube container orders are fulfilled within 10 to 14 days.
Located at the epicenter of China's wood particle and polymer trade network, we source premium PVC resins, non-toxic calcium-zinc stabilizers, and wood flours directly at source prices, passing a 15-22% cost reduction directly to our global OEM partners.
We offer over 200 standard wood-grain foil textures, deep embossing roller designs, thermal transfer patterns, and custom RAL color matching. Whether creating natural teak, smoked oak, brushed walnut, or matte architectural charcoal finishes, our consistency is guaranteed.
Every production batch undergoes strict in-line spectrophotometer color monitoring, three-point bending strength testing, boiling water moisture absorption evaluation, and formal RoHS/REACH chemical safety audits prior to dispatch.
Modern building codes prioritize low-carbon materials, reduced lifecycle maintenance, and acoustic wellness. Custom WPC Letve profiles meet these multi-dimensional criteria effortlessly across diverse architectural environments.
Vertical and horizontal WPC letve battens mounted on metal sub-frames create thermal convective airflow cavities behind facade walls. This reduces solar heat gain, improves thermal insulation efficiency, and yields visually stunning 3D shadow lines.
Suspended linear letve louvers combined with high-density acoustic polyester felt backings eliminate echo and reverberation in open-plan corporate offices, airport terminals, shopping malls, and hospitality foyers.
Because WPC letve profiles absorb less than 0.5% water, they are ideal for high-humidity interiors such as indoor pool enclosures, luxury spa wellness centers, hotel bathrooms, and subterranean entertainment spaces.
Co-extruded heavy-duty WPC letve sections function as overhead pergola slats and exterior sunshades, providing optimal solar heat rejection while withstanding high wind loads, coastal salt spray, and extreme cold frost cycles.
Architects and property developers globally are phasing out high-embodied-energy materials in favor of sustainable bio-composites. Linyi Rich New Materials' WPC letve products utilize recycled industrial polymers and post-industrial hardwood wood flour. By eliminating VOC emissions, formaldehyde binders, and toxic preservatives, our products contribute directly to earning LEED v4 Materials and Resources (MR) credits and BREEAM Environmental Ratings.
