Mesh Cable Tray Construction

A mesh cable tray system is constructed using electro-welded wire mesh sections, engineered bends, fittings, and compatible accessories to create a flexible, ventilated, and fully supported cable management pathway.

Core Components

Straight Sections: Mesh cable trays are made from electro-welded steel wires forming a rigid mesh that allows continuous ventilation and easy cable routing. Straight sections are the primary building blocks of the system and are available in various widths, heights, and shapes (U, C, G, or W) depending on application requirements. Bends and Fittings: Horizontal and vertical directional changes are achieved using engineered bends or field-fabricated bends.

Pre-engineered bends, such as C2G horizontal bends, are preferred for safety and structural integrity. Corner radius kits are used for tees and crosses to maintain cable protection and system continuity. Accessories: Complete mesh tray systems include splice plates, clamps, hangers, supports, brackets, and covers.

All accessories must be compatible with the tray material and finish to ensure grounding continuity and corrosion resistance.

Materials and Finishes

Mesh cable trays are manufactured from materials such as electro-galvanized steel, stainless steel (304 or 316), epoxy-coated steel, or tough galvanized steel. Finishes may be applied before or after fabrication depending on the type, ensuring durability in indoor, outdoor, or industrial environments.

Installation Scheme

Planning: Determine tray routing, load requirements, and cable types. Identify points for bends, tees, and dropouts. Support and Mounting: Use wall brackets, standoffs, or trapeze supports to secure trays.

Supports are spaced according to manufacturer specifications to maintain load capacity and prevent sagging. Assembly: Connect straight sections using splice plates or modular connectors. Install engineered bends for horizontal or vertical transitions.

Field-fabricated bends may be used if pre-engineered fittings are unavailable, following manufacturer instructions. Cable Loading: Feed cables into the tray, ensuring proper separation and ventilation. The open mesh design allows flexible entry and exit points for cables.

Grounding and Safety: Ensure continuous grounding across all tray sections and accessories. Safe-T-Curl edges or similar protective features prevent cable damage and enhance installer safety.

Advantages of Mesh Cable Tray Systems

Ventilation: Open mesh allows heat dissipation, reducing cable overheating. Flexibility: Easy to create bends, branches, and dropouts on-site. Scalability: Modular design supports future cable additions or re-routing.

Durability: Corrosion-resistant finishes and robust materials ensure long-term performance in industrial, data center, or outdoor environments. By following this construction scheme, a mesh cable tray system provides a safe, flexible, and efficient solution for routing and supporting electrical and data cables across diverse applications.
