Vertical Cable Tray Specifications Dimensions and Prices

Vertical cable trays are designed to safely route and support electrical cables in vertical runs, with standard widths from 50mm to 900mm, depths from 50mm to 150mm, and lengths typically of 3 meters per section.

Specifications

Vertical cable trays are engineered to support cables along vertical paths, ensuring proper ventilation, heat dissipation, and structural integrity. Key specifications include:

• Material: Common materials are galvanized steel, stainless steel (AISI 316L), aluminum, and fiberglass-reinforced polyester, chosen based on environmental conditions and corrosion resistance requirements .
• Load Capacity: Determined by material thickness, side rail height, and tray width. Ladder-type trays are preferred for heavy cable loads due to their open rung design, which allows better heat dissipation .
• Rung Spacing: For ladder trays, typical spacing ranges from 150mm to 230mm, affecting cable support and airflow .
• Finish: Options include pre-galvanized, hot-dip galvanized, powder-coated, or anodized aluminum for durability and corrosion protection .

Dimensions

Standard vertical cable tray dimensions are designed to accommodate varying cable volumes while maintaining safety:

• Width: 50mm to 900mm, with narrower trays (100–150mm) for instrumentation and control wiring, and wider trays (up to 900mm) for large industrial installations .
• Depth/Side Wall Height: 50mm to 150mm, ensuring cables remain securely in place and allowing proper airflow .
• Length: Typically 3 meters per section, which balances ease of transport and installation .
• Fill Capacity: Trays should be filled to no more than 40% of their volume to prevent overheating and allow future expansion .

Pricing Considerations

While exact prices vary by manufacturer, material, and region, factors influencing cost include:

• Material type: Stainless steel and fiberglass trays are more expensive than galvanized steel or aluminum.
• Tray width and depth: Larger trays with higher load capacity cost more.
• Accessories: Vertical bends, couplers, covers, and mounting hardware add to the total cost.
• Quantity and supplier: Bulk orders often reduce per-unit cost. For budgeting, galvanized steel vertical trays of medium width (300–600mm) and standard 3-meter length typically range from $50 to $150 per section, while stainless steel or specialized corrosion-resistant trays can exceed $200 per section, depending on specifications and local market conditions.

Installation Notes

• Vertical trays must be supported at intervals according to load and material thickness.
• Ensure proper grounding and bonding for safety.
• Maintain ventilation and spacing to prevent cable overheating.
• Use compatible fittings and covers to maintain structural integrity and code compliance . By selecting the correct width, depth, material, and fill percentage, vertical cable trays provide a safe, durable, and code-compliant solution for routing electrical cables in industrial, commercial, and renewable energy installations.
