Detailed Materials and Surface Treatments

Galvanized Cable Ladder

This type of cable tray is processed by full immersion in molten zinc, forming a robust alloy protective coating. The coating fully covers all edges and inner surfaces of the tray, delivering reliable protection against rain, moisture and ultraviolet radiation.

Application Scenarios: Overseas engineering projects, outdoor power yards, cable trenches and tunnel environments.

Core Advantages: Cost-efficient with a service life of more than 20 years. It is the most practical and preferred option for conventional outdoor and humid working conditions.

Electrostatic Powder Coated Steel

The steel substrate is first treated with phosphating, then electrostatically sprayed with epoxy or polyester powder and thermally cured to form a smooth, uniform surface layer. The finished product boasts fire resistance, UV stability and supports customized RAL color options to meet diverse aesthetic needs.

Application Scenarios: Indoor buildings, commercial complexes, data centers and dust-free clean workshops.

Core Advantages: Attractive visual effect, excellent scratch resistance and reliable electrical insulation performance.

Aluminum Alloy

Fabricated from extruded 6063 or equivalent grade aluminum alloy, these cable trays weigh just one-third of traditional steel trays. The natural oxide layer on the aluminum surface provides superior corrosion resistance without additional coating treatment. Meanwhile, the material features non-magnetic and spark-free properties for safer operation.

Application Scenarios: High-rise buildings, lightweight roof structures, equipment rooms and marine working environments.

Core Advantages: Lightweight for easy and fast installation, durable anti-oxidation performance and zero daily maintenance requirements.

Stainless Steel

Adopting 304 or 316L grade stainless steel, the tray offers exceptional resistance to acid, alkali, salt spray and high-humidity corrosion. The surface can be kept in original mill finish or further processed by passivation treatment for enhanced stability.

Application Scenarios: Coastal salt-fog areas, chemical plants, electroplating workshops, as well as food and pharmaceutical clean production zones.

Core Advantages: The optimal long-term reliable metal cable tray for severely corrosive environments, with a service life of over 30 years.

Material Selection Guide

Dry indoor environments → Electrostatic powder coated steel (cost-effective and aesthetically pleasing)

Conventional outdoor and humid sites → Galvanized Cable Ladder (best overall cost performance)

Strong acid/alkali environments and coastal marine climates → Stainless steel (priority choice)

Weight-limited scenarios and high-rise installation projects → Aluminum alloy

All the above materials can be customized with different rung spacing, load-bearing grades and matching accessories to build a safe, stable and long-lasting cable management system.

Quality Assurance

All raw materials and finished products comply with a full set of industry standards including GB/T 11253, YB/T 4001, ASTM A123, ASTM B221 and ASTM A240.
