31 45 Aluminum Tray Zxj L3

Product Overview

The HJ ZXJ-L3 series aluminum alloy cable rack is machined from 31×45 industrial aluminum alloy profile, available in single-tier and double-tier structures, with four common equipment room widths from 300 to 800mm, and cross-bars fixed to the main girder at a standard 250mm interval. The product has stable span load-bearing capacity: over a 1.5-meter span, a 150kg load produces only 5mm of deformation, and a 195kg load keeps deformation within 7mm. It 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 spacer columns ≥250mm in height to separate fiber and power cables into different tiers, reducing signal interference. The overall open, perforated structure provides good heat dissipation with clearly visible cable layout. The modular assembly requires no welding and can be cut and assembled on site, suitable for organizing fiber, network, and power cables in various indoor communication equipment rooms and data centers. Specifications can also be customized according to equipment room cabling drawings.

Key Advantages

Stable span load-bearing

The profile offers excellent rigidity, with minimal deformation under load over a 1.5-meter span, resisting sagging and deformation under long-term, dense cabling

Flexible single-tier/double-tier selection

The single-tier version suits standard equipment room cabling, while the double-tier version separates power and low-voltage cables to reduce electromagnetic interference

Lightweight, corrosion-resistant aluminum

Its weight is far lower than steel cable racks, reducing ceiling load; the natural oxide layer on aluminum provides rust protection, requiring no corrosion maintenance for long-term indoor use

Modular, rapid assembly

A complete set of uniform hanging, grounding, and tiered accessories makes on-site installation, expansion, and maintenance simple and efficient
