50 50 Aluminum Cable Tray Zxj L2

50 50 Aluminum Cable Tray Zxj L2

Product Overview

The HJ ZXJ-L2 cable tray is made from 50×50 thickened aluminum alloy profile, available in single-tier and double-tier versions, covering four common equipment room widths from 300 to 800mm, with cross-bars uniformly mounted on the main girder at 250mm intervals. The overall structure has strong load-bearing capacity, supporting up to 300kg of cable per meter. The product comes with a complete standardized installation kit — the single-tier configuration includes main girders, cross-bars, ceiling hanger rods, and floor supports, while the double-tier version additionally includes tiered spacer columns to allow fiber and power cables to be arranged in separate zones. It is suitable for various cable types in communication equipment rooms and data centers. The open, perforated layout provides good heat dissipation with clearly visible cable routing, and the modular assembly requires no welding, allowing simple on-site cutting and assembly for convenient later line maintenance and expansion. Specifications can also be customized according to equipment room cabling drawings.

Key Advantages

Thickened square tube with ultra-high load capacity

The 50×50 large cross-section aluminum alloy profile supports 300KG of cable per meter, suitable for high-density, large-volume cable laying, and resists deformation over long-term use

Single-tier/double-tier zoned cabling

The double-tier version separates power and low-voltage cables into different tiers to reduce signal interference, while the single-tier version suits standard cabling needs in small to medium equipment rooms

Complete set of standardized installation accessories

Complete hanging, support, grounding, and tiered spacer column accessories in unified specifications enable high installation efficiency

Lightweight, corrosion-resistant aluminum alloy

Its weight is far lower than steel trays, reducing ceiling load; the natural rust resistance of aluminum means no additional corrosion protection is needed for long-term indoor use
