300mm ladder tray
The Marine Cable Ladder is a specialized, heavy-duty cable support
system designed for the harsh, corrosive, and demanding
environments of the maritime and offshore industries. Unlike
standard industrial cable trays, it is engineered to withstand
constant vibration, moisture, salt spray (salt fog), extreme
temperatures, and mechanical stress encountered on ships, offshore
platforms, docks, and in coastal installations.
As a leading manufacturer and supplier of cable trays, Bending
offers high-quality cable tray solutions to meet the needs of
various harsh environments. Products are made from common materials
such as steel, aluminum alloy, or fiberglass.
300mm ladder tray Characteristics & Features
About Material
- Hot-Dip Galvanized Steel (HDG): Most common. Offers excellent strength and corrosion resistance at
a lower cost.
- Aluminum-Magnesium Alloy (Marine-grade Aluminum): Lightweight, offers superior corrosion resistance in saltwater
environments without painting, and is non-magnetic (crucial for
certain vessel types like minesweepers).
- Stainless Steel: Used in areas of extreme corrosion or for specific chemical
resistance. Often used for fittings and rungs.
About Feature
- Open Ladder Design:It provides maximum ventilation and preventing heat buildup from
cables, easy accessibility for cable installation/inspection, and
excellent heat dissipation.
- Corrosion Protection: Beyond the base anti-corrosion material, additional protection
includes polyester powder coatings, zinc plating, or anodizing.
- Load Capacity & Strength: Engineered to hold significant weight (hundreds of pounds per
linear foot) to support dense bundles of heavy copper and fiber
cables over long spans.
300mm ladder tray Structure
- Side Rails: The longitudinal beams that bear the load. Depth (height)
determines stiffness and load capacity.
- Rungs: Cross-bars that provide cable support and retention spacing.
Standard spacing is typically 225mm and 300mm.
- Fittings: A variety of components to create a complete pathway system:
- Straight Sections: Customizable.
- Tees and Crosses: For intersections.
- Reducers: To transition between different widths.
- Drops & Standoffs: To connect from the overhead ladder to cabinets/racks.

Marine Cable Ladder 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.
