Perforated Ventilated Cable Tray – Galvanized Steel, UL/CE Approved, for Data Center & Industrial Wiring
Perforated Ventilated Cable Tray – Product Introduction
Core Positioning
A galvanized / zinc-aluminum-magnesium cable tray designed specifically for high-load, high-heat-dissipation scenarios. It features elongated bottom ventilation holes and side mounting holes for efficient heat dissipation and weight reduction, ideal for data centers, industrial power distribution, building MEP systems, and more. It supports standardized modular installation.
Key Advantages
Efficient Heat Dissipation & Drainage: The bottom perforations quickly release cable heat and accumulated water, reducing cable aging risks and improving the stability of power distribution systems.
Lightweight Yet High-Strength: The ventilated design minimizes weight without compromising structural integrity, lowering transportation and installation costs while supporting long-span cabling.
Corrosion & Rust Resistance: Hot-dip galvanized or zinc-aluminum-magnesium coating provides excellent anti-corrosion performance, suitable for outdoor, humid, and chemical environments.
Fast & Easy Installation: Pre-punched standard mounting holes on side rails allow for bolted splicing, suspension, and wall mounting, boosting construction efficiency by over 30%.
Full Compliance: Available with UL, CE, and Class A1 fire ratings to meet the strict standards of data centers and international projects.
Application Scenarios
Data centers and communication rooms (for high-density cabling with critical cooling needs)
Industrial plants, chemical and power projects (corrosion-resistant, high-load wiring)
Commercial complexes and rail transit MEP engineering (lightweight, modular installation)
Optional Specifications
Materials: Hot-dip galvanized steel, stainless steel, zinc-aluminum-magnesium alloy
Sizes: Width 100–800 mm, height 50–200 mm, custom non-standard sizes available
Accessories: Matching covers, connectors, hangers, seismic brackets, etc.
FAQS
-
How to choose among solid tray, ladder tray and perforated tray?
Choose solid tray for weak current, computer rooms, dusty/humid sites and anti-interference demands; ladder tray for thick cables, high-power power circuits and workshops prioritizing heat dissipation; perforated tray for general workshops, mixed strong/weak current laying and cost control.
-
Which surface treatment for indoor and outdoor use respectively?
Electro-galvanized / fire retardant coated for dry indoor; hot-dip galvanized for outdoor & damp underground; 304 stainless steel or FRP for coastal and corrosive chemical environments.
-
What is the difference between national standard and non-standard cable trays?
National standard products strictly comply with standards on wall thickness, dimension and load capacity, passing acceptance of government, real estate and large bidding projects. Non-standard ones adopt thinner plates or customized sizes at lower prices, only suitable for small renovation without formal bidding requirements.
-
How much space should be reserved for cables inside the tray?
According to industry codes, total cross-sectional area of cables shall not exceed 40% of the tray’s inner section to reserve space for heat dissipation and future cable expansion, avoiding overheating and short circuit.
-
Cable trays are easy to deform during transportation, how do you guarantee product integrity?
Products are reinforced before shipment. Long trays are cut into segments and fixed with wooden frames for bulk orders. Free replacement of accessories or negotiated return & exchange for deformed goods received.
