Two Types of Cable Tray Systems Differentiated for Scenario-Based Applications Precisely Tailored to Industry Needs

Sep 29,2025

The selection of cable trays is increasingly following the clear trend of “scenario-driven material selection.” Galvanized and zinc-aluminum-magnesium products occupy distinct market segments based on their respective characteristics.

Hot-dip galvanized cable trays maintain dominance in indoor settings like standard industrial plants and civil buildings due to their mature manufacturing process and cost advantages. With a zinc coating thickness reaching 85μm and enhanced by passivation treatment, they deliver a 5-10 year service life in non-corrosive environments. In an automotive manufacturing workshop project, hot-dip galvanized tray-style cable trays with 30%-40% perforation rates achieved 27% higher heat dissipation efficiency than solid trays. Under uniformly distributed loads of 150kg/m, maximum deflection remained within 8mm—fully compliant with IEC 61537 standards and suitable for power cable installations. In standard office building low-voltage systems, galvanized cable trays enable 72 directional combinations through modular assembly, boosting installation efficiency by 40% while balancing practicality and cost-effectiveness.

Zinc-aluminum-magnesium cable trays demonstrate unique advantages in harsh environments, making them the preferred choice for coastal regions, chemical industrial parks, and photovoltaic power stations. In a coastal chemical project, zinc-aluminum-magnesium trays replaced traditional stainless steel products. After three years of real-world testing in a highly corrosive environment with a chloride (CL⁻) concentration of 15,000 ppm, the coating integrity rate remained above 95%, while the cost was only 60% of stainless steel. In outdoor photovoltaic power station wiring, its weather resistance supports the 25-year plant lifecycle, while its self-healing capability effectively addresses mechanical damage during construction and operation. At wastewater treatment plants, zinc-aluminum-magnesium trays withstand dual challenges of biological and chemical corrosion, extending service life over three times longer than galvanized products.

This application differentiation reflects both advancements in material technology and the precise balance between cost control and performance demands in engineering fields, driving cable installation systems toward greater efficiency and reliability.
