Where to find good tray-type cable trays

Tray-type cable trays, especially ladder and perforated trays, are widely available from specialized electrical suppliers and manufacturers like Unitrunk, Shielden, and Cable Tray Company.

Types of Tray-

Type Cable Trays

Ladder Trays: These consist of two side rails connected by rungs, allowing excellent airflow and heat dissipation, making them ideal for heavy-duty power cables and long spans in industrial settings, power plants, and outdoor installations. Perforated Trays: These have a solid bottom with ventilation holes, providing moderate airflow and good cable support. They are suitable for commercial buildings, control rooms, and indoor installations.

Solid-

Bottom Trays: Fully enclosed trays protect cables from dust, moisture, and electromagnetic interference, commonly used in data centers, hospitals, and sensitive control systems. Wire Mesh (Basket) Trays: Lightweight and flexible, these trays are easy to cut and modify on-site, ideal for IT, telecom, and low-voltage cabling. MaterialsTray-type cable trays are available in galvanized steel, aluminum, and FRP (fiber-reinforced plastic).

The choice depends on environmental exposure, load requirements, and corrosion resistance.

Where to Buy

Specialized Manufacturers: Companies like Unitrunk offer comprehensive ranges of trays and accessories for industrial and commercial projects. Electrical Supply Distributors: Suppliers such as Shielden and Cable Tray Company provide ladder, perforated, and wire mesh trays with various sizes and duty ratings. Local Electrical Wholesalers: Many regional distributors stock standard tray types and can provide guidance on sizing and installation.

Online Industrial Marketplaces: Platforms like Grainger, RS Components, and McMaster-Carr often carry a wide selection of tray-type cable trays suitable for different applications.

Selection Tips

Assess Cable Load and Type: Choose ladder trays for heavy power cables and perforated trays for moderate loads. Consider Ventilation Needs: Open designs like ladder trays improve heat dissipation, while solid-bottom trays protect sensitive cables. Check Environmental Conditions: For outdoor or corrosive environments, select trays with corrosion-resistant materials like aluminum or FRP.

Compliance and Standards: Ensure trays meet IEC 61537 or local electrical codes for safety and performance. By selecting the right type and sourcing from reputable manufacturers or distributors, you can ensure durable, code-compliant, and efficient cable management for your project.
