Ladder-type fireproof cable trays are open-frame systems designed for high-load, fire-resistant cable management, available in various materials, sizes, and customizable configurations.

Overview

Ladder-type cable trays consist of two parallel side rails connected by rigid cross rungs, forming a ladder-like structure that provides excellent ventilation, heat dissipation, and easy cable access. They are ideal for industrial, commercial, and data center installations, supporting heavy power, control, instrumentation, and fiber optic cables simultaneously .

Key Features

• Fire Resistance: Non-combustible materials and fire-retardant coatings enhance safety in high-risk environments .
• High Load-Bearing Capacity: Rigid crossbeam connections allow support for multiple cable types and heavy loads .
• Material Options: Stainless steel (304/316), galvanized steel, aluminum, and fiberglass reinforced plastic (FRP) are commonly used, offering corrosion resistance and durability .
• Ventilation and Heat Dissipation: Open ladder design ensures unobstructed airflow, maintaining low cable operating temperatures .
• Modular and Scalable: Pre-engineered components with quick-connect joints allow easy expansion, reconfiguration, and maintenance .
• Customization: Lengths typically range from 2,000mm to 6,000mm, widths from 50mm to 1,200mm, and side rail heights from 25mm to 400mm, with options for perforated or solid rungs .

Standards and Certifications

Ladder-type cable trays comply with international and national standards, including:

• GB/T 29415-2012: Steel cable tray specifications
• GB/T 23639-2009: General cable tray specifications
• JG/T 169-2005: Technical standards for construction cable ladders
• NEMA VE 1 & VE 2: Design, performance, and installation guidelines

Notable Models and Applications
