Vertical cable tray supports made of channel steel provide strong, adjustable, and corrosion-resistant support for routing cables in industrial and commercial installations.

Material and Construction

Vertical supports for cable trays are commonly fabricated from low-carbon steel, stainless steel, or aluminum alloys, often with corrosion-resistant finishes such as pre-galvanized coating (ASTM A653M G90/G60) or hot-dip galvanization (ASTM A123/BS EN ISO 1461:2009) to ensure durability in harsh environments . The steel channels are typically cold-formed and feature continuous slots along their length, allowing flexible attachment points for cable trays, brackets, and fittings .

Standard Dimensions

Channel steel supports are generally available in standard lengths of 2000 mm or 3000 mm, with custom lengths available upon request . The width and thickness of the channel are selected based on the weight and number of cables to be supported, ensuring structural stability. Typical channel tray widths range from 1.5 to 6 inches, depending on cable load and spacing requirements .

Installation and Mounting

Vertical channel supports can be mounted to walls, floors, or structural steel frameworks. For concrete structures, anchors such as M10, M12, or M16 bolts are used, while for steel frameworks, hex bolts (M10) are common . The continuous slots in the channel allow for adjustable positioning of cable trays, vertical bends, and fittings, facilitating easy alignment and height adjustment .

Compatibility and Accessories

Channel steel supports are compatible with solid or ventilated cable trays, cable ladders, and mesh trays. Accessories such as fittings, junction plates, covers, and strain reliefs can be attached directly to the channel supports, enabling secure and organized cable routing . Ventilated channels often include burr-free punched holes for cable ties, improving cable management and airflow .

Advantages

• High load capacity for heavy cable installations
• Corrosion resistance with galvanization or stainless steel options
• Flexibility due to slotted design for adjustable mounting
• Ease of installation with standard lengths and compatible fittings
• Durability in industrial and commercial environments Vertical cable tray supports made of channel steel are therefore a reliable and versatile solution for safely routing and supporting cables in a wide range of applications, from industrial plants to commercial buildings.
