Explore factory-direct architectural panels manufactured under ISO9001 and CE stringent quality systems.
A Modernized Global Enterprise Integrating Advanced R&D, Automated Production Lines, and International Supply Chains.
Linyi Rich New Materials Co., Ltd. is a professional modernized industrial and trading company, integrating research & development, production, and sales, dedicated to the manufacturing and innovation of new environmentally friendly building materials. Headquartered in Linyi City, Shandong Province, the company operates an intelligent production base covering over 100,000 square meters and employs over 300 professional technicians.
With its industry-leading production scale, proprietary formulation engineering, and exceptional product quality, the company has established itself as a cornerstone supplier in the global architectural composite sector. From high-density flat WPC wall panels and co-extruded outdoor decking to acoustic wood slats and SPC rigid core flooring, our infrastructure is engineered to deliver enterprise-level OEM and ODM solutions.
Understanding the material science, polymer extrusion physics, and surface treatments driving modern wood-plastic composites.
Our flat WPC panels utilize ultra-pure High-Density Polyethylene (HDPE) or modified PVC matrices combined with 60% processed hardwood flour. Synthesized with maleic anhydride grafted coupling agents (MAPE), this creates an impenetrable interphase bond preventing moisture absorption.
Employing state-of-the-art co-extrusion technology, each flat panel features a 360-degree protective outer shell containing Hindered Amine Light Stabilizers (HALS) and nano-scale titanium dioxide. This guarantees zero fading, chalking, or surface micro-cracking under intense solar radiation.
Using automated laser-guided calibration units, panel thickness tolerances are maintained within ±0.15mm across large format boards. Surface choices span 3D thermoformed wood textures, brushed matte architectural tones, and mirror UV lacquers.
In rigorous laboratory testing (ASTM & ISO standardized methods), custom flat WPC panels outperform raw timber, fiber cement, and standard aluminum cladding across key structural and environmental parameters:
| Performance Metric | Custom Flat WPC Panel | Natural Solid Timber | Standard Aluminum Cladding | Fiber Cement Board |
|---|---|---|---|---|
| Moisture Absorption (24h immersion) | < 0.5% (Non-swelling) | 18% - 35% (High risk of warping) | 0% (Corrosion prone if scratched) | 7% - 12% (Brittle when wet) |
| Flexural Modulus (MPa) | ≥ 2,800 MPa | 1,100 - 1,800 MPa | N/A (Sheet metal) | 1,200 MPa |
| Fire Reaction Rating | B1-s1, d0 (EN13501-1 / ASTM E84) | Class B3 / Class C (Combustible) | Class A1 (Non-combustible) | Class A1 (Non-combustible) |
| Formaldehyde Degassing | E0 / Zero Formaldehyde | Variable (Depends on sealant) | Zero | Zero |
| Maintenance Cycle | 15-25 Years (Zero Staining/Sealing) | 1-2 Years (Requires sanding & oiling) | 5 Years (Cleaning required) | 3-5 Years (Repainting needed) |

How shift toward sustainable construction, carbon neutrality targets, and total cost of ownership are reshaping international building material sourcing.
Global developers and commercial contractors are under strict mandates to lower embodied carbon. Custom flat WPC sheets replace energy-intensive ceramic tiles and deforestation-linked virgin timber. Formulated with up to 85% recycled materials, our panels directly contribute to earning points under LEED v4 Materials and Resources credits.
With global construction labor costs rising exponentially, developers prefer flat WPC wall panels featuring tongue-and-groove or click interlocks. These panels reduce wall finish installation times by up to 65% compared to traditional wet plastering, tiling, or multi-coat wood painting.
While raw lumber requires ongoing staining, varnishing, and pest treatment every 12-18 months, custom flat WPC panels remain maintenance-free. Commercial properties, hotels, and residential complexes achieve total return on investment within 3 years due to zero maintenance expenditure.
Modern interior designers demand custom visual textures—ranging from realistic synchronized wood grain (EIR) and industrial cement to ultra-gloss UV marble. Our high-precision engraving and lamination tech enables exact matching of designer specs on flat WPC substrates.
Visualizing real-world applications across hotel lobbies, exterior facades, acoustics projects, and luxury residential interiors.

Flat WPC panels offer a continuous, smooth surface designed to emulate solid wood boards, polished stone, or modern matte architectural finishes. Unlike fluted or 3D grating panels with deep grooves, flat WPC panels are ideal for seamless wall cladding, full-scale veneer paneling, and wide-plank applications where zero dirt accumulation and easy cleaning are paramount.
Because the wood fibers are completely encapsulated in hydrophobic high-density polymer matrices during co-extrusion, flat WPC panels exhibit near-zero water absorption (<0.5%). They will not swell, rot, delaminate, or harbor mold spores, making them vastly superior to traditional MDF, plywood, or natural wood in humid environments.
Our flat WPC formulations incorporate inorganic flame-retardant additives (such as aluminum trihydrate). They achieve Class B1-s1, d0 fire reaction ratings according to European Standard EN 13501-1 and Class A flame spread performance under ASTM E84, self-extinguishing within seconds without releasing toxic dripping droplets.
Standard stocked colors have a flexible MOQ starting at 300 square meters. For custom OEM specifications (custom extrusion profile, unique surface printing, or precise length cuts), the MOQ is typically 1,000 square meters per color. Production lead time averages 10 to 15 days upon deposit confirmation for standard 40ft high-cube containers.
Yes. However, outdoor applications require our specific Co-Extrusion Outdoor WPC formulation engineered with UV stabilizers and high-density HDPE. Interior grade PVC-based flat WPC panels should not be installed in direct sunlight. Our technical engineering team provides exact material matching based on your project's climate exposure.
Installation is simple and fast. Panels are mounted onto wood/metal furring strips or directly onto flat drywall using structural polyurethane adhesive combined with concealed metal clips or small stainless steel brad nails along the tongue edge. Standard woodworking tools (miter saws, hole saws) can be used to cut and route the panels effortlessly.
