Modernized Industrial Base & World-Class OEM/ODM Wood-Plastic Composite Manufacturing Hub
Linyi Rich New Materials Co., Ltd. is a leading modernized industrial and trading enterprise integrating advanced material research & development, continuous extrusion production, and global B2B distribution. Headquartered in Linyi City, Shandong Province—China's primary logistics and wood-processing capital—our facility serves as an authoritative manufacturing center for exterior WPC sliding gates, architectural wall cladding, SPC flooring, acoustic slat panels, and decorative composite systems. With over 300 technical specialists and rigorous ISO9001 certification, we fulfill global procurement demands with uncompromising quality and compliance.
Why Commercial & Residential Projects Are Transitioning to Co-Extruded WPC Sliding Gate Systems
Traditional wrought iron gates suffer from severe oxidation, heavy operational load, and frequent repainting. Solid timber gates warp, split, and degrade under UV exposure and rain. Co-extruded WPC sliding gates combine structural aluminum internal skeletons with high-density wood-plastic composite profiles, offering absolute weatherproofing with natural timber optics.
Enterprise procurement directors evaluate Total Cost of Ownership (TCO). WPC sliding gates require no staining, oiling, or anti-rust coatings. The protective polymer shield withstands high-salinity coastal environments, thermal cycles from -40°C to +60°C, and heavy industrial usage without color fading or material rot.
Designed to integrate flawlessly with automatic sliding gate operators (rack-and-pinion electric motors, infrared safety sensors, access control keypads, and IoT smart home systems). The lightweight yet high-flexural composition reduces torque strain on motor actuators, extending system lifespan.
Technical breakdown of polymer matrices, wood fiber ratios, structural reinforcements, and co-extrusion technology.
A premium WPC sliding gate is not merely a plastic board; it is an engineered hybrid material system. The primary board consists of approximately 60% premium poplar wood fiber, 30% recycled High-Density Polyethylene (HDPE), and 10% chemical additives including UV stabilizers, coupling agents (maleic anhydride grafted polyethylene), antioxidant complexes, and flame retardants.
| Physical / Mechanical Property | Testing Standard | Engineered Target Value | Commercial Impact |
|---|---|---|---|
| Flexural Strength (Modulus of Rupture) | ASTM D790 / EN 310 | ≥ 28.5 MPa | Prevents gate panel sagging across spans up to 6 meters. |
| Water Absorption Rate | ASTM D570 / EN 317 | < 0.5% (24hr submersion) | Zero swelling, mold-free operation in tropical/rainy zones. |
| Linear Thermal Expansion Coefficient | ASTM D696 | < 3.8 × 10⁻⁵ / °C | Controls thermal expansion, keeping gate tracks aligned. |
| UV Weathering Resistance (Accelerated) | ISO 4892-2 (3000 Hours) | Grey Scale Rating ≥ 4-5 | Minimal color shift over 15+ years of intense sun exposure. |
| Fire Performance Rating | EN 13501-1 / ASTM E84 | Class B1 / Class B Flame Spread | Meets commercial perimeter security fire compliance. |
| Wind Load Resistance | EN 12424 Standard | Class 4 (Up to Beaufort Scale 11) | Structural integrity during extreme storms & gale winds. |
Our advanced 2nd-generation co-extrusion technology encases the inner composite core in an ultra-durable outer shell made of fluorocarbon-modified polymers. This shell acts as an impenetrable barrier against scratches, chemical staining, acid rain, and fungal decay, guaranteeing that exterior WPC sliding gates retain their original aesthetics without maintenance.
WPC sliding gate frames engineered by Linyi Rich incorporate high-tensile 6063-T5 anodized aluminum alloy or hot-dip galvanized steel structural tubing. The WPC slats slot into engineered aluminum channels with expansion gaps, ensuring thermal movement is absorbed internally without warping the main gate frame.
Direct insights into scale, cost efficiencies, automated tooling, and OEM capability at Linyi Rich.
With 120 automated WPC grating lines and 40 dedicated outdoor extruders, we process tens of thousands of metric tons of composite material annually, lowering per-unit production costs for international buyers.
Equipped with state-of-the-art CNC precision engraving and custom profile tooling machines, allowing bespoke slatted patterns, louvers, 3D wood textures, and custom dimensions within short lead times.
We source ultra-pure HDPE pellets and refined hardwood fiber directly. Every batch undergoes melt flow index (MFI) testing, moisture content check, and impact resistance validation prior to extrusion.

Ensuring seamless import, environmental safety, and regulatory compliance across Europe, North America, Middle East, and Australia.
Exporting high-performance WPC sliding gates requires strict adherence to international building codes and environmental directives. Linyi Rich New Materials Co., Ltd. operates in full compliance with the following international standards:
For Middle Eastern and Australian regions, WPC gate formulations are boosted with specialized UV absorbers (HALS - Hindered Amine Light Stabilizers) to prevent polymer chain scission under solar radiation exceeding 200 kLy/year.
For Nordic and North American winter climates, our composite matrix undergoes 20 freeze-thaw cycles (-40°C to +50°C), maintaining micro-structural cohesion with zero internal micro-cracking or impact degradation.
Versatile design integrations across residential, commercial, and industrial sites.
Horizontal louvers and full-privacy slatted WPC sliding gates providing high security, acoustic dampening against street noise, and warm teak/walnut wood aesthetics matching modern villa facades.
Heavy-duty automated wide-span cantilever WPC sliding gates built to endure high duty cycles, automated RFID card entry, and heavy industrial vehicular traffic.
Where steel gates corrode within 24 months, salt-proof WPC profiles and aluminum hardware provide permanent, rust-free gate solutions for beachfront hotels and marine estates.
