Explore our top-tier engineering lines manufactured to rigorous international standards (ISO9001, CE, ASTM, REACH).
Linyi Rich New Materials Co., Ltd. is a modernized industrial enterprise integrating research & development, ultra-precision extrusion manufacturing, and global sales. Dedicated to high-performance, eco-friendly composite building solutions, we operate a smart manufacturing infrastructure engineered for global scalability.
How advanced wood-polymer matrix technology is reshaping contemporary architectural engineering, structural porticos, and exterior facade aesthetics globally.
The global construction sector is undergoing a structural transition toward decarbonized, low-lifecycle-cost materials. Traditional timber columns suffer from thermal warping, termite infestation, and moisture absorption, while solid steel columns pose thermal bridging and corrosion challenges. Custom Wood-Plastic Composite (WPC) columns resolve these limitations through a synthesized matrix of high-density thermoplastics and micro-milled lignocellulosic fibers, offering superior tensile strength and carbon neutrality.
From commercial resort pergolas in the Middle East to architectural porticos across North America and Europe, procurement demands for hollow and reinforced WPC structural profiles have surged by 14.2% CAGR. Municipal contracts, hospitality developments, and high-end residential projects increasingly specify WPC column profiles due to zero-maintenance requirements and UV-stable surface capping technologies.

| Maintenance & Refinishing | Bi-annual staining / painting | Powder coat touch-ups required | Zero Refinishing (Integrated UV-328 Stabilizers) |
| Fire Performance Rating | Class C / Untreated combustible | Non-combustible | Class B1-s1, d0 Flame Retardant (EN 13501-1) |
| Customization Capabilities | Manual carpentry (High cost) | Extrusion (High tooling MOQ) | Full OEM/ODM Profiles, Fluted/Square/Round Extrusion |
How our centralized logistics and massive extrusion infrastructure deliver tier-one quality at optimal cost efficiency.
Operating 120 automated WPC grating extrusion lines, 40 dedicated outdoor climate WPC profile lines, and specialized CNC engraving infrastructure, our factory eliminates human error while maintaining high throughput. This continuous production capacity ensures predictable lead times even during global supply disruptions.
With over 200 standard and custom extrusion molds, we provide rapid prototyping for architectural drawings. Whether your project requires square fluted columns, hollow structural wraps, or round load-bearing sleeves, our tooling shop delivers custom profiles within 14 calendar days.
From raw material resin melt-flow index testing to spectrographic color matching and artificial weathering chamber testing (Q-SUN Xe-3), every batch of WPC columns leaves our facility backed by full traceable test certificates (COA).
Custom WPC columns provide structural aesthetic harmony across diverse engineering environments.
Used as primary or secondary upright supports, WPC columns resist harsh solar radiation, torrential moisture, and salt air in coastal resorts, urban parks, and outdoor dining facilities without splitting or chalking.
Serving as decorative structural wraps around steel core posts, WPC column profiles add warmth and modern lines to modern office buildings, retail fronts, and residential entrances.
With formal indoor VOC emission compliance (E0 Grade), interior-rated WPC column profiles and ceiling-to-floor structural battens create elegant visual partitions in hotel lobbies, corporate headquarters, and high-end residential suites.
