Specifications of square tubes for cable tray supports

Square tubes for cable tray supports are typically made of steel or stainless steel, with dimensions and wall thickness selected based on load requirements, span, and environmental conditions.

Material and Corrosion Protection

Square tubes used for cable tray supports are generally steel or stainless steel, often with galvanized or powder-coated finishes to enhance corrosion resistance in industrial environments. Stainless steel (AISI 316) is preferred for high-corrosion areas, while pre-galvanized steel is common for indoor installations.

Dimensions and Load Capacity

Common sizes: Square tubes range from 25x25 mm to 100x100 mm, with wall thicknesses from 1. 5 mm to 4 mm, depending on the load and span. Load class: The tube size is selected based on the span between supports and the weight of the cable tray and cables.

Larger spans or heavier loads require thicker or larger square tubes. Structural strength: Tubes must support the cable tray without excessive deflection, ensuring mechanical stability and safety.

Mounting and Support

Square tubes can be used as vertical posts, horizontal beams, or cross members in cable tray support structures. They are typically mounted using: Base plates bolted to floors or wallsSuspension brackets from ceilingsCross braces for lateral stability Standards and ComplianceCable tray support systems, including square tubes, should comply with: DIN EN 61537 for cable support systemsNEMA VE 1 for metal cable tray systemsUL or CE certifications for structural and electrical safety Practical ConsiderationsSpan and deflection: Ensure the tube size limits deflection under full load. Environmental conditions: Choose corrosion-resistant finishes for outdoor or humid environments.

Integration with fittings: Square tubes must accommodate brackets, clamps, and other mounting accessories for cable trays. In summary, selecting square tubes for cable tray supports involves balancing material, size, wall thickness, and mounting method to meet mechanical load requirements and environmental conditions while complying with relevant standards.
