Price of Low Voltage Shielded Cable Trays

Low voltage shielded cable trays typically range from $20 to $150 per foot, depending on material, size, and shielding features.

Overview

Low voltage shielded cable trays are designed to safely route low-voltage and data cables while minimizing electromagnetic interference. They are commonly made from powder-coated galvanized steel, stainless steel, or wire mesh, and may include additional shielding elements to reduce stray fields in sensitive environments such as hospitals, laboratories, and industrial facilities .

Price Range

• Wire Mesh Trays: Standard low-voltage wire mesh trays, such as those from Legrand, generally cost $20–$50 per foot for basic sizes (e.g., 4-inch side rails, 30-inch width) and can increase with larger widths or patented load-optimized designs .
• Shielded or Specialized Trays: Trays with integrated shielding to reduce electromagnetic interference, like Systron CableShield systems, can cost $80–$150 per foot or more, depending on the shielding material, current rating, and installation complexity .
• Bulk or Custom Orders: Suppliers on platforms like Alibaba offer customizable low-voltage cable trays in bulk, which can reduce per-foot costs but vary widely based on dimensions, finish, and quantity .

Factors Affecting Price

1. Material: Stainless steel and corrosion-resistant coatings increase cost.
2. Tray Size: Wider or deeper trays carry higher prices.
3. Shielding Requirements: Additional electromagnetic shielding or fire-retardant coatings add to the cost.
4. Quantity and Supplier: Bulk orders or direct manufacturer purchases can lower unit prices.
5. Compliance and Certification: Trays meeting NEMA, CSA, or RoHS standards may be priced higher due to quality assurance .

Recommendations

• For standard low-voltage installations, wire mesh trays from Legrand or McMaster-Carr provide reliable, cost-effective solutions.
• For sensitive environments requiring electromagnetic shielding, consider specialized systems like Systron CableShield, which are designed to reduce stray fields and protect equipment and personnel .
• Always request quotes from multiple suppliers to account for shipping, customization, and local availability. By considering these factors, you can select a low voltage shielded cable tray that balances cost, performance, and compliance for your project.
