Cable tray support standard size price

Standard cable tray supports typically accommodate tray widths from 50mm to 900mm, depths from 25mm to 150mm, and lengths of 2–3 meters, with prices varying by material and load capacity.

Standard Dimensions

Width: Cable tray supports are designed to fit trays with nominal widths ranging from 50mm to 900mm, with common widths including 100mm, 200mm, 300mm, 450mm, and 600mm. The width determines the number of cables that can be laid side-by-side and affects airflow and heat dissipation . Depth/Height: Standard side rail heights or tray depths range from 25mm to 150mm, depending on cable volume and ventilation requirements. Deeper trays allow more cables but may reduce airflow efficiency . Length: Most cable trays and their supports are supplied in 2–3 meter sections, which balances ease of transport with installation efficiency. Supports are designed to match these lengths for proper load distribution . Material Thickness: Thickness varies by tray type and load requirements. Heavy-duty trays typically have 2.5mm or greater thickness with reinforced side rails, while light-duty trays may use thinner materials. Material choice affects load capacity, span, and long-term durability . Tray Types: Supports are compatible with ladder, perforated, channel, and wire mesh trays. Each tray type has different structural requirements: ladder trays prioritize width and side rail height for heavy loads, perforated trays balance ventilation and containment, and wire mesh trays offer flexibility with lighter loads .

Pricing Overview

Cable tray supports are priced based on material, size, and load capacity:

• Light-duty steel or aluminum supports: approximately $10–$25 per meter.
• Medium-duty galvanized steel supports: approximately $20–$40 per meter.
• Heavy-duty or stainless steel supports: approximately $35–$70 per meter, depending on thickness and reinforcement. Additional costs may include mounting hardware, brackets, and connectors, which are typically sold in sets with the supports .

Installation Considerations

• Supports must be spaced according to tray load and span requirements, typically 1.5–3 meters apart for straight runs.
• Ensure compatibility with tray type and width to prevent deflection or cable damage.
• Allow 40–50% free space in the tray for ventilation and future expansion .

Summary

Standard cable tray supports are engineered to match tray widths of 50–900mm, depths of 25–150mm, and lengths of 2–3 meters, with material thickness and type selected based on load requirements. Prices vary widely, from $10 to $70 per meter, depending on material and duty rating. Proper sizing and spacing are critical for safe, code-compliant installations and long-term durability.
