Galvanized steel cable trunking tray with cover
Galvanized steel cable trunking tray with cover is a fully enclosed cable management system designed to provide mechanical protection, EMI shielding, and organized routing for power, control, and data cables. Manufactured from cold-rolled steel (Q235B) with a hot-dip galvanized or electro-galvanized finish, the trunking features a U-shaped trough base and a matching removable cover that protects cables from dust, moisture, and physical impact. The cover is secured with spring-loaded clips or screw fasteners, allowing easy access for cable installation and maintenance. Standard sections are available in lengths up to 3000mm with widths from 50mm to 600mm and heights from 50mm to 150mm, making this system suitable for industrial, commercial, and infrastructure applications requiring reliable cable containment and protection.
Full cable enclosure
Removable cover provides complete protection against dust, debris, moisture, and physical impact, ensuring cable integrity.
Galvanized corrosion protection
Hot-dip or electro-galvanized finish provides effective corrosion resistance for indoor and covered outdoor installations.
EMI shielding capability
Enclosed steel construction provides electromagnetic interference shielding for sensitive control and data cables.
Easy cable access
Removable cover with quick-release clips allows rapid cable installation, inspection, and maintenance without dismantling.

FREQUENTLY ASKED QUESTIONS
○ What is the difference between trunking and cable tray?
Trunking is a fully enclosed system with a cover that provides complete cable protection, dust resistance, and EMI shielding. Cable tray is an open system that supports cables without full enclosure, offering better ventilation but less protection. Trunking is preferred where mechanical protection, dust prevention, or shielding is required.
○ How is the cover secured to the trunking base?
Standard trunks use spring-loaded clips that snap over the cover edge, providing secure retention while allowing easy removal. For high-vibration or security applications, screw-down fasteners are available. Clips are positioned at regular intervals along the cover (typically every 300-500mm).
○ Can the trunking be used outdoors?
Yes. For outdoor use, we recommend hot-dip galvanized finish with a minimum 50μm coating thickness, combined with outdoor-rated cover fasteners. For marine or high-corrosion environments, stainless steel or heavy-duty galvanized versions are available.
○ Does the trunking provide EMC/EMI protection?
Yes. The steel enclosure provides natural electromagnetic shielding. For enhanced EMC performance, we recommend bonding the trunking sections together using grounding jumpers and ensuring continuous electrical conductivity across joints and to the earth reference.
INSTALLATION GUIDELINES
Support spacing should not exceed 1.5 meters for standard loads; reduce to 1.2 meters for heavy cable fills or outdoor installations.
Ensure covers are properly aligned and fully engaged with clips or fasteners to maintain dust protection and prevent rattling.
For EMC applications, install grounding bonding jumpers across each trunking joint to ensure electrical continuity.
STORAGE & MAINTENANCE
Store trunking in a dry, ventilated area to prevent moisture condensation and potential white rust formation on galvanized surfaces.
Inspect cover clips and fasteners periodically for damage or wear; replace any clips that have lost spring tension.
For powder-coated finishes, touch up any scratches with matching paint to maintain corrosion protection.
