Product Description
Aluminum Alloy Cable Trays are premium cable management solutions engineered for harsh outdoor and corrosive environments. Constructed from high-strength aluminum alloys (typically 6063-T5 or 6005A-T6), these trays offer an optimal balance of lightweight design, corrosion resistance, and mechanical durability. The alloy composition provides natural resistance to rust and oxidation, while the extruded or pressed profiles feature reinforced ribs and cross-members to enhance load-bearing capacity without adding excess weight.
The trays are available in ladder, perforated, and solid-bottom configurations, with surface treatments including anodizing, powder coating, or PVDF painting to further enhance corrosion resistance in extreme conditions. The open design promotes airflow and cable cooling, while the smooth edges and rounded corners protect cables from abrasion during installation. Compatible with standard fittings and supports, they can be easily customized for length, width, and load requirements.
Features
Exceptional Corrosion Resistance: Aluminum’s natural oxide layer provides immunity to rust, with anodized finishes offering 10+ years of protection in coastal or chemical-rich environments, outperforming galvanized steel trays by 3-5 times.
High Strength-to-Weight Ratio: Up to 50% lighter than steel trays while maintaining comparable load capacity (150-400 kg/m), reducing installation costs and structural load on buildings.
Thermal and Electrical Conductivity: Efficient heat dissipation prevents cable overheating, while the non-magnetic properties make them ideal for high-frequency signal cables in radar and communication systems.
Weatherproof Design: UV-resistant coatings and tight-fitting joints protect against rain, snow, and extreme temperatures (-50°C to +150°C), ensuring reliable performance in desert, arctic, and tropical climates.
Eco-Friendly and Recyclable: Aluminum is 100% recyclable without loss of properties, aligning with sustainable infrastructure goals and LEED certification requirements.
Application
Aluminum Alloy Cable Trays excel in environments where traditional metal trays would fail due to corrosion or weight:
Coastal Installations:
Offshore wind farms, marine terminals, and lighthouses, resisting saltwater spray and humidity without compromising cable protection.
Chemical Plants and Refineries:
Handle exposure to acidic gases, solvents, and industrial pollutants, with PVDF-coated trays offering superior resistance to harsh chemicals like sulfuric acid.
Outdoor Power Grids:
Route high-voltage cables in substations, solar farms, and transmission lines, where lightweight design simplifies installation in remote or elevated locations.
Transportation Infrastructure:
Used in railway tunnels, metro systems, and airport runways, combining corrosion resistance with compliance to fire and smoke safety standards (EN 45545-2).
Mining and Metallurgy:
Withstand dusty, wet, and abrasive conditions in mines and smelters, protecting control cables for machinery and safety systems.
FAQ
Q: How does the corrosion resistance compare to stainless steel?
A: While stainless steel offers better resistance to certain chemicals, aluminum alloy trays are lighter, more cost-effective, and ideal for general outdoor and saltwater environments.
Q: Can they be used for grounding purposes?
A: Yes, aluminum is a good conductor, and the trays can be grounded using stainless steel bonding jumpers; ensure proper insulation from dissimilar metals to prevent galvanic corrosion.
Q: What is the maximum span between supports?
A: Standard spans are 1.5-3 meters, depending on tray type and load; heavy-duty ladder trays can span up to 6 meters with reinforced cross-members.
Q: Do you offer fire-resistant versions?
A: Aluminum itself is non-combustible, but for high-temperature environments, we recommend adding fireproof covers or using our hybrid aluminum-ceramic trays rated for 4 hours of fire resistance.
Q: Can the trays be painted to match project aesthetics?
A: Yes, powder coating and PVDF painting are available in a wide range of colors, with the anodized base providing additional protection under the paint layer.
