Anlu Cable Tray Specifications

Anlu aluminum cable trays are lightweight, corrosion-resistant, and designed for high load capacity with easy installation for both indoor and outdoor applications.

Material and Construction

Anlu cable trays are made from aluminum, which is lighter than steel, making them easier to handle and install while maintaining high strength and durability . The trays feature extruded I-beam side rails with welded rungs, and all edges and welds are rounded to prevent cable damage . The rungs are often reversed every second rung to allow top or bottom mounting of cable ties and clamps . Aluminum trays are highly resistant to corrosion, including in wet or saltwater environments, and are suitable for both indoor and outdoor use .

Load Capacity and Design

Anlu trays are engineered to support high loading capacities, with a safety factor of 1.5. Each tray section can handle an additional 200 lb concentrated load on any portion of the tray beyond the published load class . Standard trays are designed with rungs spaced 12 inches apart and widths typically around 36–42 inches, with deflection measured at the midpoint for simple spans. Continuous spans can reduce deflection by up to 50% . The trays are ventilated to allow airflow, preventing cable overheating, and the maximum open spacing between transverse elements does not exceed 102 mm (4 in.), .

Installation Features

Anlu aluminum trays are designed for fast and easy installation, with snap-in splice plates provided for each straight section . The lightweight design reduces labor costs, and the trays can be adapted to various configurations, including ladders and ventilated designs, to manage dense cable transitions . Adequate clearances should be maintained for supports and future expansion, with a minimum of 50% expansion allowance in width and height .

Environmental and Safety Considerations

Aluminum trays are non-magnetic, fire-resistant, and do not produce toxic gases in case of fire . They are suitable for harsh environmental conditions, including chemical exposure, and maintain structural integrity over time . Compliance with standards such as CSA, UL, and NEMA ensures safety and reliability in industrial and commercial installations .

Summary

Anlu aluminum cable trays combine lightweight construction, high load capacity, corrosion resistance, and ease of installation, making them ideal for a wide range of applications from industrial facilities to commercial buildings. Their design ensures cable protection, thermal management, and long-term durability, while meeting recognized safety and performance standards .
