Types of Cable Trays for Long Spans

Ladder Cable Trays are the most suitable for long spans, typically ranging from 10 to 24 feet. Their open rung-and-rail design allows for superior airflow, reduces heat buildup, and supports heavy power cables over extended distances . Wire Mesh Trays are lightweight and flexible, ideal for data centers or installations requiring frequent modifications. While not as heavy-duty as ladder trays, they can be used for medium-span applications with proper support . Solid Bottom Trays provide maximum protection against dust, debris, and environmental exposure. They are suitable for outdoor or corrosive environments but may require additional support for very long spans .

Key Considerations

• Load Capacity: Ensure the tray can support the weight of all cables over the intended span. Ladder trays generally offer the highest capacity for long spans .
• Material and Corrosion Resistance: Galvanized or stainless steel trays are preferred for durability and outdoor use .
• Customization and Support: Choose manufacturers that offer tailored solutions, technical guidance, and installation support for complex or long-span projects .
• Compliance: Verify that the trays meet relevant standards such as DIN EN 61537 for cable support systems . For large-scale or industrial projects, Atkore International, Legrand, and OBO Bettermann are among the best choices due to their proven reliability, product variety, and global availability. Selecting ladder-style trays from these manufacturers ensures safe, efficient, and long-lasting cable management for long-span installations.
