Cable Tray Specifications and Color Chart

Cable trays come in various models, materials, and finishes, including gray, black, pre-galvanized, hot-dip galvanized, and powder-coated options, with specifications tailored to load, span, and environmental conditions.

Cable Tray Models

Ladder Tray: Features side rails with rungs for cable support, ideal for heavy-duty applications and long cable runs. Commonly used in data centers and industrial installations (Hubbell NEXTFRAME® Ladder Tray). Channel Tray: U-shaped or C-shaped, suitable for short cable runs or aesthetic applications, available with solid or ventilated bottoms.

Wire Mesh Tray: Made of welded steel wire, lightweight and flexible, often used for instrumentation and control cables. Solid or Perforated Tray: Solid trays provide maximum protection, while perforated or ventilated trays allow heat dissipation and airflow.

Materials and Finishes

Steel: Pre-galvanized or hot-dip galvanized for corrosion resistance; suitable for industrial and outdoor environments. Stainless Steel: AISI 316L grade for high corrosion resistance, especially in chlorinated or marine environments. Aluminum: Lightweight, corrosion-resistant, and easily formable; ideal for indoor and outdoor use.

Fiberglass Reinforced Plastic (FRP): High resistance-to-weight ratio and excellent corrosion resistance, suitable for chemical or wet environments.

Powder-

Coated or Painted: Available in gray, black, or custom colors to match equipment or aesthetic requirements.

Specifications

Width and Depth: Varies by model; common widths range from 100 mm to 600 mm or more, with depths from 50 mm to 150 mm. Load Capacity: Defined by tray type, material, and support span; ladder trays typically support heavier loads than wire mesh trays. Rung Spacing: Ladder trays usually have 150–230 mm spacing to maintain cable support and proper bend radius.

Compliance: Most trays meet NEMA, UL, and CE standards, ensuring safety and performance. Installation: Can be mounted on floors, walls, ceilings, or equipment racks; modular systems allow easy configuration and expansion.

Color Considerations

Gray and Black: Common for data centers and equipment rooms to match racks and cabinets.

Custom Powder-

Coated Colors: Available for aesthetic or identification purposes in commercial or industrial projects.

Summary

When selecting a cable tray, consider model type, material, finish, load capacity, environmental conditions, and compliance standards. Ladder trays are preferred for heavy loads, wire mesh for flexibility, and solid or channel trays for protection or aesthetics. Color options include gray, black, and custom powder-coated finishes to suit project requirements.
