Standard for Angle Steel Cable Trays

Angle steel used to support cable trays must comply with recognized standards such as BS EN 61537, NEMA VE 1/VE 2, and CSA C22. 2, ensuring proper load-bearing, material selection, and secure installation. Key Standards and GuidelinesBS EN 61537 specifies requirements for cable tray systems, including metal trays, ladder trays, and associated supports.

It emphasizes that support elements, such as angle steel, must be designed to withstand the weight of cables, equipment, and environmental loads like wind or snow, without compromising safety or structural integrity.

NEMA V

E 1 and VE 2 provide detailed guidance for metal cable tray systems, including channel, ladder, and solid-bottom trays. These standards define load/span classes, material specifications, and installation practices for support elements. Angle steel used as a support must be sized according to the tray type, span length, and expected load, and it should be securely fastened to the building structure.

CS

A C22. 2 harmonizes with NEMA standards in Canada, ensuring that metal cable tray supports meet electrical code requirements and mechanical safety criteria.

Installation Considerations

Material Selection: Angle steel should be made of galvanized or stainless steel to resist corrosion, especially in industrial or outdoor environments. Load Capacity: Supports must account for tray weight, cable weight, and imposed loads such as equipment or environmental forces. The spacing of angle steel supports should follow the span ratings provided in NEMA VE 1/VE 2 or BS EN 61537.

Mounting: Angle steel can be attached to walls, ceilings, or structural beams using appropriate fasteners and brackets. Ensure that the support is level and aligned to prevent tray deformation or cable strain. System Compatibility: Use components that are tested together as a system to maintain safety and structural integrity.

Practical Tips

For long spans, consider intermediate supports to reduce deflection. Avoid using angle steel as a walkway or ladder; it is intended solely for mechanical support of cable trays. Follow manufacturer recommendations for fastening hardware and corrosion protection.

By adhering to these standards and guidelines, angle steel supports will provide safe, durable, and code-compliant support for cable tray installations.
