I-beam cable tray support installation

Cable trays can be securely supported on I-beams using specialized mounting clips, brackets, and hardware kits designed for I-beam ladder trays.

Beam Cable Tray OverviewI-beam cable trays are a common ladder-style design used in industrial and commercial installations. They are typically made from 6063 T6 aluminum, which provides a lightweight, corrosion-resistant structure suitable for heavy loads, sometimes exceeding 100 pounds per foot on spans up to 30 feet. The I-beam design allows for hold-down clips and expansion guides to be positioned either inside or outside the tray, offering flexibility in installation.

Support MethodsI-Beam Mounting Clips These clips are specifically designed to attach cable trays directly to structural I-beams. They provide a secure connection without the need for welding or drilling into the beam, simplifying installation and reducing labor time.

Beam Support Hardware Kits Complete hardware kits include brackets, fasteners, and corrosion-resistant components for supporting I-beam ladder trays. These kits are designed for heavy-duty applications and are compatible with standard fittings and accessories, ensuring proper alignment and load distribution.

Stand-

Off Brackets Stand-off brackets can be used to maintain a gap between the cable tray and the I-beam, allowing for airflow, cable bending, and easier maintenance. These brackets are available in various sizes and load ratings to match the tray and installation requirements.

Installation Considerations

Ensure the I-beam can support the combined weight of the cable tray and cables. Use corrosion-resistant materials for outdoor or humid environments. Maintain proper spacing between supports according to the tray manufacturer's recommendations to prevent sagging.

Verify compatibility with NEMA or CSA load classes if required for regulatory compliance.

Additional Resources

For design modeling and planning, BIM objects for cable trays and horizontal racks can be downloaded for Revit, SketchUp, or other CAD software, which helps in visualizing support placement and load distribution. By using the appropriate mounting clips, hardware kits, and stand-off brackets, cable trays can be safely and efficiently supported on I-beams, ensuring long-term stability and compliance with load requirements.
