Explore our factory-direct composite roofing, wall cladding, and high-performance architectural panel solutions manufactured under ISO9001 and international quality frameworks.
Linyi Rich New Materials Co., Ltd. stands at the global apex of modernized composite material manufacturing. As a fully integrated enterprise uniting advanced industrial research, precision polymer engineering, and large-scale manufacturing, we deliver architectural-grade WPC roof systems, outdoor structural decking, interior wall cladding, acoustic engineering panels, and resilient SPC flooring.
Headquartered in the manufacturing hub of Linyi City, Shandong Province, our smart manufacturing base occupies over 100,000 square meters. Backed by a high-caliber workforce including over 300 professional technicians, we guarantee strict compliance with international building directives, ISO9001 Quality Management standards, and rigorous CE/ASTM physical performance benchmarks.
The international building materials industry is undergoing a structural paradigm shift. Driven by net-zero carbon mandates, stringent energy efficiency building codes, and escalating lifecycle maintenance costs associated with traditional metal, clay, or asphalt roofs, Custom Wood-Plastic Composite (WPC) Roof Panels have emerged as the gold standard for contemporary architectural envelopes.
WPC roofing systems utilize 60% recycled natural hardwood flour combined with high-density polyolefins, slashing Embodied Carbon footprint by up to 42% compared to conventional standing-seam steel or concrete tile roofing.
Unlike metal roofs susceptible to electrochemical corrosion and acoustic resonance during heavy rain, co-extruded WPC roofs offer superior sound attenuation (up to 28dB reduction) and total immunity to acidic corrosion.
With a exceptionally low thermal conductivity coefficient (K-value < 0.15 W/m·K), custom WPC roof panels act as continuous thermal breaks, drastically reducing HVAC energy expenditure in hot ambient zones.
Linyi Rich New Materials Co., Ltd. utilizes next-generation dual-screw co-extrusion technology. Our custom WPC panel roof matrix integrates nano-fluorocarbon cap-stock layers with high-density polyolefin core formulations, providing unparalleled UV resistance, fire retardancy (B1/ASTM E84 Class A), and zero moisture swelling.

Architectural demands vary radically across global geographic biomes. Our engineered WPC roof panels and architectural profiles are custom-tailored to excel in extreme macro-climatic environments:
Engineered to withstand intense solar radiation and ambient temperatures over 50°C. Formulated with titanium dioxide UV reflectors and modified thermal stabilizers to eliminate warping and thermal decay.
Interlocking structural tongue-and-groove profiles designed to meet hurricane wind-uplift pressures (UL 580 Class 90), offering total resistance to salt-spray oxidation.
Complete anti-microbial bio-barrier protection stops fungal hyphae and termite infestation, making WPC roofing ideal for South-East Asian and South American resorts and residential developments.
In addition to custom WPC roof structures, Linyi Rich New Materials Co., Ltd. operates state-of-the-art production lines catering to full-building envelope customization:
