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 primary log processing and synthetic composite hub of Asia—the company operates an intelligent production base covering over 100,000 square meters and employs over 300 professional technicians and industrial engineers. With its leading production scale, rigorous quality verification protocols, and exceptional product quality, the company has established itself as a major supplier in the building materials sector worldwide.
The global demand for Wood-Plastic Composite (WPC) panels—commonly referenced in Latin American and European markets as Painel WPC—has experienced exponential growth over the past decade. Driven by stringent global ESG (Environmental, Social, and Governance) policies, carbon neutrality mandates, and high timber costs, civil engineering firms and interior architectural planners are rapidly replacing traditional natural wood with engineered thermopolymer composites.
According to current market intelligence, the global WPC market value is projected to expand at a CAGR of over 11.4% from 2024 to 2030. Key drivers for this shift include:
Unlike natural timber, which absorbs atmospheric moisture leading to fungal rot, swelling, and termite invasion, high-density WPC formulation provides 100% resistance against water degradation and bio-fouling.
Eliminates periodic sanding, oiling, varnish applications, and structural sealing. Modern co-extrusion technology embeds a protective UV-resistant polymer shield, reducing long-term OPEX for commercial operators.
Utilizing recycled HDPE/PVC substrates combined with pulverized wood fiber (a timber byproduct), WPC panels adhere to strict E0/E1 formaldehyde release standards and qualify for LEED green building credits.
The manufacturing process of industrial-grade Painel WPC requires precise thermodynamic controls, chemical coupling agents, and twin-screw extrusion parameters. At Linyi Rich New Materials Co., Ltd., raw materials undergo micro-milling and vacuum thermal blending to guarantee homogenously integrated thermoplastic composite structures.

Procuring directly from specialized Chinese custom WPC factories provides enterprise buyers, real estate developers, and international distributors with unbeatable scale economies and rapid prototyping agility. As an industry anchor based in Linyi City, Linyi Rich New Materials Co., Ltd. integrates the complete upstream and downstream supply chain under one roof.
Operating 120 dedicated WPC grating lines and 40 outdoor panel lines enables continuous 24/7 automated production, lowering unit conversion costs while achieving an annual capacity exceeding 12 million square meters.
Our in-house CNC mold engineering shop can design, cut, and calibrate specialized profile molds (fluted, semicircular, tongue-and-groove, or 3D embossed acoustic geometry) within 10 to 14 working days.
Adhering strictly to ISO9001 quality management standards, every production lot undergoes standardized flexural load testing, boiling water bath delamination tests, impact resistance checks, and colorimetry audits.
Linyi Rich New Materials Co., Ltd. maintains a diversified, multi-category manufacturing architecture designed to meet all modern architectural, acoustic, and interior design requirements:

To support global procurement managers and private-label distributors, Linyi Rich New Materials Co., Ltd. provides a streamlined end-to-end original equipment manufacturing (OEM) workflow:
Technical consultation to define profile geometry, wall thickness tolerances, click-system dimensions, and density requirements.
In-house precision CNC machining of high-grade alloy steel extrusion dies, followed by thermal calibration and trial sample runs.
Exact matching of target Pantone hues, natural wood grain PVC films, or hot-stamping foils with high anti-fading performance.

From high-traffic luxury commercial hospitality hubs to exterior building facades exposed to aggressive weather elements, engineered WPC panels deliver structural reliability alongside cutting-edge modern aesthetics.
Efficient freight optimization is crucial for international wholesale trade. WPC products possess significant structural weight, making container volumetric packing efficiency vital for minimizing shipping overhead per square meter.
Painel WPC combines the aesthetic warmth of natural timber with the structural resilience of high-density polymers. Unlike timber, WPC will not absorb atmospheric water (water absorption rate < 0.5%), eliminating rot, warp, splintering, and mold expansion. Furthermore, WPC requires no routine sealing, staining, or anti-termite chemical treatments, resulting in significantly lower lifecycle costs.
We utilize computerized color spectrophotometers to maintain batch-to-batch Delta E color variation below 1.0. For laminated or foil-finished lines, we source high-grade PVC films with UV inhibitors tested for 1,500 continuous hours under accelerated QUV weatherometer conditions without noticeable color shifts.
Custom mold design and sample extrusion prototyping typically require 10 to 14 days. Once mold approval is secured, standard bulk container orders (40HQ) are manufactured, inspected, and prepared for shipping port delivery within 15 to 20 business days.
Yes. Our interior and exterior WPC panels are engineered with inorganic flame-retardant additives. They achieve B1-s1, d0 fire performance under European Standard EN 13501-1 and Class A flame spread ratings under ASTM E84, ensuring safety for public spaces, hotels, and office buildings.
For interior WPC wall panels, installation uses stainless steel starter clips, tongue-and-groove interlocking clips, and structural polyurethane adhesive applied directly over flat drywall or plywood framework. Outdoor WPC decking utilizes heavy-duty aluminum or composite joists, stainless steel hidden fasteners, expansion screws, and matching WPC trim edges.
