A wide span aluminum cable tray is an open structural support built from high-strength aluminum alloy and optimized to bridge long distances between supports. Taller side rails, reinforcing ribs and carefully placed rungs raise longitudinal bending stiffness so the tray spans 6 meters, 9 meters or more between hangers-far beyond the 1.5–3 meter range of standard trays-while deflection is kept within L/200 under full cable load. Aluminum's low density keeps the assembly light on the building structure, and its natural oxide film resists atmospheric corrosion without an extra coating. The result removes intermediate supports that clutter open industrial and commercial spaces.
We deliver the wide span aluminum cable tray as a structurally customized, drawing-engineered product. Each project's span length, cable load and hanger layout are calculated from the drawings, and the cross-section-rail height, rib count, rung position-is sized to hold deflection within target rather than shipped from a generic profile. Because structural dimensions are set to the drawing, buyers get predictable long-span performance without over-specifying material weight, and long, uninterrupted runs can be planned into the same structural system.

Applications
- Large industrial workshops and logistics warehouses have few convenient ceiling hanger points; the 6–9 meter spans eliminate frequent support columns and keep floor space open for racks and equipment.
- Airport terminals and commercial atriums need clean, uncluttered cable routes across broad open areas; the long-span aluminum profile presents a sleek, light visual line.
- EMI-sensitive control rooms and communication halls benefit from the non-magnetic aluminum, which avoids eddy-current heating while clearing long spans above open floor plates.
Customization
We customize span length, rail height and profile, rib configuration, rung spacing, tray width, end connector and hanger layout, all fabricated to project structural drawings.
Packaging & Transportation
Assembled or sectional units are packed in fumigation-free plywood crates reinforced for long-distance transport. Terms: FOB, EXW, DDP; payment by T/T.
FAQ
Q: How is the long span confirmed for my load?
A: We work from your layout drawings, cable weight and required span, sizing the rail profile so deflection stays within L/200 under full load.
Q: Does the long-span aluminum tray need additional anti-corrosion coating?
A: Its natural oxide layer suits atmospheric and damp environments; for constant immersion or heavy chemical exposure we can discuss surface options.
Q: Can the hanger and support layout be supplied along with the trays?
A: Yes, the support and connector layout is engineered with the tray profile from the same drawing set.
