Perforated (ventilated / vented) cable trays designed to improve airflow around cables, reduce tray weight, and support clean routing for power and control systems. Ideal for projects where heat dissipation and moisture drainage are required without fully enclosed covers.
A perforated cable tray is a ventilated (vented) cable support system with a punched bottom surface that allows airflow, heat dissipation, and drainage while still providing continuous side-rail guidance for cables.
Compared with solid-bottom trays, perforated designs reduce weight and improve cooling, making them suitable for many indoor and semi-outdoor routes. Compared with ladder trays, perforated trays offer a more continuous support surface for smaller cables and dense cable runs.

Corrugated perforated bottom optimized by FEM for higher inertia moment and improved loading capacity with ventilation.
Compact corrugated perforated tray for narrow routes and smaller cable bundles. Standard length, customizable.
Simple, economical ventilated tray with stable performance for wide applications and standard lengths.
Reinforced structure designed to reduce support points and installation time across long straight sections.
Embossed perforated base plate with reinforced bars for higher strength and material efficiency.
Double reinforced sides for enhanced stiffness under long-span runs, suitable for many straight sections.
* Standards reference: IEC 61537, NEMA VE1, JB/T 10216.

A perforated cable tray is selected when cable routes require a balance between structural support and airflow. This structure supports heat dissipation, visual inspection, and flexible routing—making it suitable for general industrial, commercial, and utility installations.
Perforated openings allow natural airflow around power and control cables, helping reduce heat buildup and supporting stable operation under continuous load.
Tray width, side height, thickness, and perforation pattern are selected together to meet load requirements while maintaining reasonable weight and installation efficiency.
Perforations simplify cable tie fixing, drop-out routing, and on-site adjustments, making this structure suitable for systems with frequent changes or future expansion.
Available in pre-galvanized steel, HDG, stainless steel (304/316), and aluminum. Finishes can be selected for indoor, outdoor, and mildly corrosive environments.
Perforated cable trays (ventilated trays) are specified when projects need a practical balance of cable support and airflow. The perforation pattern supports heat dissipation, improves inspection visibility, and helps with drainage in areas exposed to sprinklers or washdown—making it a reliable choice for industrial, commercial, and infrastructure installations.
Common for plant corridors where stable support and easy maintenance are required. Perforations improve ventilation and simplify visual checks during commissioning and routine inspections.
Selected for cable runs where heat dissipation matters. Ventilated bottoms help reduce heat buildup and support more stable operation under continuous load.
Suitable where water exposure is possible. Perforations support drainage and reduce water accumulation, while still providing structured cable support for maintenance routes.
Widely used for building MEP routing where cable fixing, branching, and future changes are expected. Ventilated trays support tidy layouts and easier field adjustments.
A perforated (ventilated) cable tray is specified when routes need structured support plus airflow. In practice, the tray is delivered as a system—straight sections plus splice plates, covers (as required), dividers, and mounting—so long runs stay aligned, serviceable, and easy to inspect over time.
Need direction changes and branching parts (tees, risers, crosses)? See Cable Tray Fittings. For cover options, dividers, joining hardware, and fixing parts, see Cable Tray Accessories.
Use when routes need extra shielding while keeping a ventilated tray base.
Clamps and tie points help secure cables and maintain separation and bend control.
Separate power/control/instrument cables and keep routing organized in shared runs.
High-strength joints to keep long runs rigid and aligned with stable support spacing.
Hangers, cantilevers, rails, and fasteners selected by load, span, and installation method.
Perforated (ventilated) cable trays are selected when projects need airflow, heat dissipation, and easier inspection while still maintaining organized routing. Selection focuses on load, support spacing, perforation pattern, and corrosion protection—then coordinated into a complete routing scope for installation.
To confirm perforated tray configuration and real ventilation performance, the following inputs are typically reviewed:
Once conditions are confirmed, perforated cable trays are supplied as a coordinated routing system:
Share your route layout, support spacing, and cable loading. We’ll confirm tray width & side height, recommend material and finish, and return a project-ready BOM covering ventilated straight sections, routing fittings, and accessories for fast installation.
