Aluminum Alloy Channel-Type Combined Cable Tray

ODN and passive infrastructure knowledge brief Published 27 Feb 2024

Prepared for preliminary research by the GESTIONVAL ODN knowledge desk. Confirm network topology, split ratio, box or cabinet capacity, joint closure rating and loss budget against current standards and product documentation.

Aluminum alloy channel cable trays are lightweight, corrosion-resistant systems available in solid or ventilated designs, with various widths and fittings to suit industrial and commercial installations.Material and Alloy Types

Aluminum channel cable trays are typically fabricated from Aluminum Association Alloy 6063 for extruded components and Alloy 5052 for fabricated parts, providing a balance of high strength, corrosion resistance, and thermal performance suitable for harsh or coastal environments . These alloys are often anodized to enhance durability and prevent corrosion .

Tray Designs

Aluminum channel trays are available in two main bottom types:

  • Solid Bottom: Provides full support for cables, ideal for sensitive or high-density cable runs where protection from dust or debris is required .
  • Ventilated Bottom: Features perforations or slots to allow airflow, improve heat dissipation, and facilitate cable tie installation. Ventilated trays often have burr-free oblong holes and slots for securing cables .
Standard Widths and Load Capacity

Channel trays come in nominal widths of 1.5, 3, 4, and 6 inches, with a minimum loading depth of approximately 1.25 inches . Aluminum trays are lightweight, reducing structural load and easing installation, yet they can support additional concentrated loads on side rails or rungs beyond standard load classes .

Fittings and Configurations

Fittings allow for directional changes, size adjustments, and bends in the tray system. Options include:

  • Horizontal and vertical bends with zero or custom radii (e.g., 12 in., 24 in.)
  • Tee, cross, and reducer fittings for branching or connecting trays
  • Snap-in splice plates for easy assembly and field modifications
Applications and Advantages

Aluminum alloy channel trays are ideal for industrial, commercial, and coastal installations due to their:

  • Lightweight construction for easier handling and reduced labor costs
  • Superior corrosion resistance compared to steel, especially in outdoor or high-humidity environments
  • Thermal management for high-density cable runs, improving safety and cable longevity
  • Electromagnetic shielding in sensitive installations These trays are CSA and UL certified, meeting NEMA standards for safety and performance . In summary, aluminum alloy channel cable trays offer versatile, durable, and lightweight solutions for cable management, with options for solid or ventilated bottoms, multiple widths, and a variety of fittings to accommodate complex routing and environmental requirements.
