Should cable tray supports be made of hangers or angle steel

Both hangers (rod supports) and angle steel supports are viable for cable trays, but the choice depends on load requirements, installation environment, and adjustability needs.Rod (Hanger) SupportsRod supports, often called hangers, consist of threaded rods, bases, and supporting components. Their main advantages include:Height Adjustability: Rod supports allow precise vertical positioning of cable trays, making them ideal for installations where height flexibility is crucial .Ease of Installation: They can be installed quickly without welding, and adjustments can be made by simply rotating the rod .Versatility: Suitable for complex layouts or retrofits where cable trays need to be repositioned or aligned with other services . Rod supports are commonly used in commercial buildings, data centers, or areas where frequent modifications or height adjustments are expected.Angle Steel SupportsAngle steel supports are made from steel angles, fasteners, and connectors, typically welded or bolted in place. Their key features include:Structural Stability: Angle steel provides strong resistance to deformation, ensuring long-term stability under heavy loads .Wide Load-Bearing Range: They can support both light and heavy cable tray systems, making them suitable for industrial environments .Durability: Once installed, angle steel supports are robust and can withstand vibrations, mechanical stress, or impacts . These supports are ideal for factories, power substations, or manufacturing plants where mechanical stress and environmental challenges are significant.Selection ConsiderationsWhen deciding between hangers and angle steel supports, consider:Load Requirements: Heavy cable trays or long spans may benefit from the rigidity of angle steel.Installation Environment: Rod supports are better for flexible layouts, while angle steel excels in high-stress or industrial settings.Future Adjustments: If trays may need repositioning, rod supports offer easier modifications.Corrosion and Material: Both supports are typically made of steel or stainless steel, with galvanization or coatings applied for corrosion protection .ConclusionUse rod supports (hangers) for adjustable, flexible installations and angle steel supports for heavy-duty, stable, and industrial applications. The final choice should balance load, environment, and maintenance considerations to ensure long-term performance and safety .
