Heavy-Duty FRP/GRP Ladder Type Cable Tray

Maximum Airflow. Industrial Strength. Ultimate Corrosion Defense.

The preferred choice for high-power cabling in aggressive environments.

When managing heavy power cables, heat dissipation and load-bearing capacity are critical. Qingdao Chengda Huili New Materials Co., Ltd. delivers premium FRP Ladder Cable Trays featuring robust solid side rails and high-strength rungs.

Unlike solid-bottom trays that trap heat, our Ladder Type design allows for free air circulation, preventing cable derating while offering the structural integrity needed to span long distances. It is the gold standard for oil, gas, and power generation industries.

? Why Choose Ladder Type Trays?

Designed for performance, our ladder trays combine the lightweight properties of fiberglass with the engineering logic of heavy steel.

• Superior Heat Dissipation: The open design prevents heat buildup in power cables, allowing them to operate at maximum efficiency (Ampacity).

• Easy Cable Exit/Entry: Cables can drop out or enter at any point along the run without cutting the tray sidewalls—ideal for complex distribution layouts.

• High Load Capacity: Constructed with Solid Pultruded Side Rails (C-Channel or I-Beam profile), our trays meet NEMA and IEC load classes, capable of supporting heavy armored cables over long spans.

• No Dust Accumulation: The open rung structure prevents the buildup of flammable dust, moisture, or corrosive sludge.

⚙️ Technical Specifications

We manufacture to strict international standards to ensure compatibility and safety.

Design Note: Our rungs are mechanically locked and chemically bonded to the side rails, ensuring they never rotate or detach under heavy cable pulling loads.

?️ Proven Applications

Qingdao Chengda Huili Ladder Trays are the backbone of infrastructure in:

1. Offshore Platforms & Ships: Resisting saltwater corrosion while carrying main power feeds.

2. Chemical & Refineries: Withstanding acidic fumes that dissolve steel trays in months.

3. Power Plants: Managing high-voltage cables where heat ventilation is a safety requirement.

4. Tunnels: Lightweight installation reduces the load on tunnel ceilings.

? The Qingdao Chengda Huili Standard

• Pultrusion Technology: We use continuous automated pultrusion to ensure every meter of tray has consistent resin-to-glass ratio and structural strength.

• Pre-Assembled: Trays can be shipped assembled (ready to install) or knocked-down (CKD) to save massive amounts on ocean freight.

• UV Protection: All trays come with a UV-rich surface veil or synthetic surfacing fleece to prevent "fiber bloom" outdoors.

? Power Your Project with Confidence

Stop replacing rusty steel trays. Invest in a system that lasts as long as your facility.
