Key Performance Features
1. Lightweight
The density of aluminum alloy is about 2.7g/cm³, only one third of steel (7.85g/cm³). Under the same specifications, the weight of aluminum alloy closed cable tray is about 60%~70% lighter than steel trays, greatly reducing transportation costs and installation labor intensity.
2. Inherent Oxidation Resistance and Non-Rusting
Aluminum alloy naturally forms a dense aluminum oxide film on its surface in the natural environment, preventing further oxidation of the underlying metal. This characteristic allows it to remain rust-free for a long time in conventional environments without additional coating, especially suitable for high-humidity or mildly corrosive indoor locations.
3. Good Thermal Conductivity and Heat Dissipation
The thermal conductivity of aluminum alloy is about four times that of steel (approximately 200 W/(m·K) vs 45 W/(m·K)). When cables generate heat during operation, the tray quickly conducts and dissipates the heat, avoiding local overheating of cables, effectively extending the life of cable insulation and reducing the risk of line failure.
4. Electromagnetic Shielding Performance
The fully enclosed aluminum alloy structure creates a Faraday cage effect, effectively shielding external electromagnetic interference while also preventing internal cables from radiating outward, suitable for data centers, communication rooms, and other places with strict signal integrity requirements.
Core Advantages
Reduces Support Load
The lightweight characteristic directly reduces the load requirements on building structures and supports. In vertical shafts of high-rise buildings, it reduces the specification and quantity of supports per floor; in long-span horizontal installations, it allows the use of lighter cantilever brackets or hangers, saving steel and installation costs.
Convenient Installation
Aluminum alloy is easy to cut, drill, and trim on site without heavy cutting equipment. The tightening torque requirements for connecting bolts are lower, and with quick connectors, installation efficiency can be greatly improved. A single person can handle long sections of the tray, reducing labor costs.
Long Service Life
Under normal indoor conditions, aluminum alloy closed cable trays require no regular anti-corrosion maintenance and can achieve a service life of more than 30 years. Even with minor surface scratches, the oxide film self-repairs, unlike galvanized steel which may suffer from rust propagation.
Aesthetic and Environmentally Friendly
The aluminum alloy surface can be anodized in silver-white, bronze, or electrostatically sprayed in various colors, presenting a bright and neat appearance that coordinates with modern building interior finishes. The material is 100% recyclable, meeting green building evaluation standards.
