For delicate instrumentation cables, fiber optics, and control wiring, an open tray isn't enough. You need a fortress. Qingdao Chengda Huili New Materials Co., Ltd. presents our Solid Bottom FRP Cable Trunking, designed to provide a fully enclosed, corrosion-resistant shield against dust, moisture, chemicals, and physical damage.
Unlike open ladder trays, our Trunking systems (Ducts) come with secure covers, making them the ultimate choice for environments where cable hygiene and security are paramount.
Standard PVC trunking becomes brittle in the sun, and steel trunking rusts in humidity. Our Fiberglass Reinforced Plastic (FRP) solution offers the perfect balance of durability and protection.
Total Enclosure: The solid bottom design paired with a heavy-duty cover prevents the ingress of dust, water, and corrosive sludge. It also stops rodents from chewing on sensitive wires.
Corrosion Immunity: Manufactured from premium pultruded resins, our trunking survives in acid plants, wastewater facilities, and marine environments where metal fails.
Electromagnetic Interference (EMI) Shielding: While non-conductive, the solid structure helps physically separate sensitive data cables from power lines, reducing signal interference issues.
UV Stable: Engineered with UV inhibitors to withstand direct sunlight without chalking or cracking.

Our trunking systems are pultruded for maximum longitudinal strength and uniform wall thickness.

Qingdao Chengda Huili Cable Trunking is the standard for protecting the "nervous system" of industrial plants:
Instrumentation & Control: Protecting 4-20mA signal cables and PLCs in chemical plants.
Telecommunications: Routing fiber optic cables where physical protection is critical.
Food & Beverage: Sealed systems that are easy to wash down and don't trap bacteria.
Under-floor Routing: Protecting cables in server rooms or sub-floor voids.
Outdoor Rooftops: Protecting solar (PV) wiring from harsh weather and UV rays.
Seamless Connections: We provide a full range of molded fittings (elbows, tees, risers) that match the trunking profile perfectly, ensuring there are no gaps for dust to enter.
Smooth Interior: Our trunking features a resin-rich inner surface that is ultra-smooth, preventing cable snagging during pulling.
Custom Colors: While Grey is standard, we can manufacture Red (Fire Safety) or Blue (Intrinsically Safe) trunking for easy system identification.
Don't leave your critical wiring exposed. Upgrade to the fully enclosed protection of Qingdao Chengda Huili FRP Trunking.
