Precision-engineered composite profiles, acoustic wall slating, and decorative architectural systems.
Linyi Rich New Materials Co., Ltd. stands at the forefront of sustainable polymer-matrix materials manufacturing. As a modernized, highly integrated industrial and international trading corporation, we seamlessly unify advanced research and development (R&D), high-precision extrusion manufacturing, and strategic international distribution. We are dedicated to pioneering high-performance, eco-friendly building materials designed to replace traditional timber and minimize environmental footprint across global building facades and commercial interiors.
Headquartered in Linyi City, Shandong Province—China’s premier logistics and wood industry hub—our state-of-the-art intelligent manufacturing complex spans more than 100,000 square meters. Backed by a high-caliber workforce of over 300 professional engineers and senior technicians, our enterprise operates advanced automated extrusion lines, modern cleanrooms, and stringent ISO9001-certified quality control frameworks.
Why leading architectural firms and international procurement directors choose Wood-Plastic Composite (WPC) hollow tubes and louvers over traditional timber or pure aluminum.
Natural timber suffers from severe weather degradation, termites, moisture swelling, and costly periodic painting. WPC tubular profiles replicate warm wood grain aesthetics via specialized surface treatments while offering total immunity to rot, fungal decay, and insect attack.
The engineered tubular and hollow core configuration drastically optimizes structural weight-to-strength ratios. It reduces dead-load pressure on curtain walls, steel sub-frames, and suspended linear ceiling systems, enabling faster installation and lower structural costs.
WPC tubular louvers function as external solar screens (brise-soleil) and interior acoustic baffles. The hollow interior chamber breaks standing acoustic waves, significantly absorbing reverberation when coupled with acoustic backing felts.

Our factory maintains an extensive stock of standard tooling molds with a daily output across 120 lines. Standard profile orders are typically fulfilled within 10 to 15 days for a 40-foot high-cube container (FCL). Custom die development and color matching require an additional 7 to 10 working days.
Indoor WPC tubes utilize PVC or light PE polymer binders optimized for fire retardancy (B1-s1), low VOC emissions, acoustic dampening, and refined timber surface foils. Outdoor WPC tubular louvers utilize high-density polyethylene (HDPE) combined with UV stabilizers, antioxidants, and co-extrusion caps to withstand thermal cycles, rain, and heavy solar UV without cracking.
Yes. While individual WPC tubes are rigid extrusions, they are installed onto flexible aluminum tracks or segmented radius framework. By adjusting the spacing (pitch) between parallel vertical tubes, installers can create smooth visually continuous curved partitions, cylindrical columns, and wave acoustic ceilings.
We provide complimentary sample kits containing various profile cross-sections, WPC tubular colors, surface finishes (embossed, sanded, foil wrapped), and technical data sheets for engineering evaluation upon request.
