High Strength & Rigidity 300mm Ladder Tray 2m/3m Length

Product Specification

300mm ladder tray

The Cable Ladder is a prefabricated structural system used to securely support and manage large volumes of power cables, data/communication cables, and other services in industrial, commercial, and infrastructure projects.Unlike solid-bottom cable trays, its runged design offers superior ventilation and accessibility.

300mm ladder tray Features

• Open Design: Rungs provide maximum air circulation around cables, reducing heat build-up and improving ampacity (current-carrying capacity).
• High Strength & Rigidity: Designed to carry heavy cable loads over long spans without significant sagging.
• Exceptional Accessibility: Cables can be installed or removed from anywhere along the run without disturbing adjacent cables, facilitating easy modifications.
• Ventilation & Heat Dissipation: Optimal for power cables where heat management is critical.
• Durability: Manufactured from robust materials with various protective coatings for long service life in harsh environments.

300mm ladder tray Structure

The ladder tray system is modular and consists of the following main parts:

• Side Rails (Stringers): The two longitudinal members that form the sides of the ladder. They are typically made of rolled steel channel or perforated steel and provide the primary structural strength.
• Rungs: Solid or serrated cross-members welded or bolted at regular intervals (typically 225mm or 300mm centers) between the side rails. They directly support the cables.
• Fittings: Various accessories to complete the system:
• Bends: Horizontal and vertical elbows to change direction.
• Tees & Crosses: For branching cable routes.
• Reducers: To transition between different widths.
• Covers: Can be added where falling debris or limited touch protection is needed.
• Support System: Includes cleats, brackets, hangers, and trapeze systems suspended from the building structure. Supports are typically spaced from 1.5m to 6m apart, depending on load and ladder strength.

300mm ladder tray Materials & Finishes

The material is chosen based on environment, load, and corrosion requirements.

Carbon Steel (Mild Steel):

Most common. High strength, economical.

Finish: Hot-Dip Galvanized (HDG) - Standard for most industrial applications, providing excellent corrosion resistance. Powder Coated - Adds an additional layer of protection and color coding (e.g., black, grey, red for fire circuits).

Stainless Steel:

Grades 304 (general corrosion resistance) and 316 (superior resistance to chlorides/saline environments).

Used in food & beverage, pharmaceutical, marine, and highly corrosive atmospheres.

Aluminum:

Lightweight, naturally corrosion-resistant, and non-magnetic.

Ideal for data centers, telecom, and coastal areas. Does not require painting.

300mm ladder tray Advantages

• High Load-Bearing Capacity: Ideal for heavy-duty power cables (e.g., HV/MV) and dense cable bundles.
• Long Support Spans: Fewer supports required compared to solid-bottom trays, reducing installation time and cost.
• Future-Proofing: Easy to add, remove, or reroute cables to accommodate system expansions or changes.
• Safety: Provides organized, elevated routing, protecting cables from ground hazards (water, physical damage). Proper grounding creates a continuous earth path.
• Cost-Effective: Lower initial material cost than some alternatives and significant savings in long-term maintenance and modification.

300mm ladder tray Applications

• Cable ladders are the preferred solution in environments requiring robustness and high cable capacity:
• Power Plants & Substations: For main cable runs from generators, transformers, and switchgear.
• Industrial Facilities: Manufacturing plants, oil & gas refineries, chemical plants.
• Data Centers: For overhead power distribution to server racks and cooling units.
• Transportation Hubs: Airports, railway stations, for extensive power and control systems.
• Commercial High-Rises: For vertical risers and plant room cable management.
• Water & Wastewater Treatment Plants.
• Tunnels & Bridges: For lighting, control, and monitoring systems.
