1. Product Summary
The Hot-Dipped Galvanized Trunk is a fully enclosed, rigid conduit system designed to provide maximum physical protection and segregation for cables. Fabricated from mild steel sheet and protected by a robust Hot-Dip Galvanizing (HDG) coating, it offers exceptional durability and corrosion resistance in demanding environments. Unlike ladder or perforated trays, its seamless, enclosed design shields cables from dust, moisture, light debris, and accidental impact, making it the ideal choice for exposed installations, harsh industrial settings, and areas requiring enhanced safety and neatness. It is a high-strength, maintenance-free solution for routing and protecting critical power, control, and instrumentation cables.
2. Product Description
The Hot-Dipped Galvanized Trunk, often called a cable trunking system or enclosed channel, provides the highest level of cable containment. Its primary function is to create a secure, shielded pathway that guards against external mechanical damage and environmental contaminants.
The product's resilience comes from the hot-dip galvanizing process, where the fabricated steel trunk is fully immersed in molten zinc. This creates a thick, metallurgically bonded coating that protects the base metal from rust and corrosion, ensuring a long service life even in challenging conditions.
With a removable or hinged cover secured by a robust latching mechanism, it offers unparalleled accessibility for cable installation, inspection, and maintenance, while maintaining a clean and professional appearance.
Core Advantages:
Superior Physical Protection: Fully enclosed design guards cables against impact, crushing, dust, dripping water, and unauthorized access.
Exceptional Durability: The hot-dip galvanized coating provides outstanding resistance to rust and atmospheric corrosion, suitable for both indoor and outdoor use.
Enhanced Safety & Neatness: Contains cables securely, preventing snagging hazards and presenting an organized, professional installation. Can improve fire compartmentalization.
Easy Access for Maintenance: The removable cover allows for quick addition, removal, or inspection of cables without dismantling the entire system.
High Mechanical Strength: Steel construction provides rigidity and support over long spans, protecting cables from sagging and stress.
Main Product Styles:
Standard Trunking: Rectangular cross-section with a screw-fixed or quick-release cover. Most common for wall-mounted or overhead runs.
Skirting/Dado Trunking: Integrates cable management with architectural elements, often featuring compartments for power, data, and accessories.
Multi-Compartment Trunking: Features internal dividers to segregate different cable types (e.g., power vs. data) within a single unit for EMI protection and compliance.
Typical Applications:
Industrial Plants & Manufacturing Floors (exposed routes)
Power Generation & Utility Substations
Transportation Hubs (airports, railway stations)
Water & Wastewater Treatment Facilities
Commercial Buildings for main risers and critical pathways
3. Product Details
| Item | Specification Details |
|---|---|
| Base Material | High-quality mild steel sheet (typically S350GD to EN 10346 or equivalent). |
| Corrosion Protection | Hot-Dip Galvanized (HDG) post-fabrication, in accordance with ISO 1461 or ASTM A123. Standard coating thickness typically ≥85µm. |
| Construction | Formed from a single sheet with welded seams for high integrity. Cover attaches via continuous hinge or separate fasteners (stainless steel screws or latches). |
| Standard Sizes (H x W) | Common sizes: 50x50mm, 75x75mm, 100x50mm, 100x100mm, 150x100mm, 200x200mm. A wide range of custom sizes is available. |
| Standard Lengths | Typically 3 meters. Other lengths (2.5m, 4m) can be supplied. |
| Internal Fitments | Optional dividing plates and mounting DIN rails for internal equipment organization. |
| Coupling & Accessories | Galvanized couplers, internal/external bends, tees, reducers, end caps, and mounting brackets. All accessories are HDG for consistent protection. |
| Surface Finish | Standard spangled zinc finish. Can be powder-coated post-galvanizing for aesthetic purposes or color-coding (e.g., safety yellow). |
| Ingress Protection (IP) Rating | Typically rated up to IP54 (dust and water splashed from any direction) with gaskets on the cover. Higher ratings (IP55/IP66) achievable with sealed designs. |
| Compliance Standards | Manufactured to comply with IEC 61537, EN 50085 (cable trunking standards), and relevant national building codes. |
| Fire Performance | The steel construction is inherently non-combustible. Systems can be designed to meet specific fire resistance ratings for compartmentation. |
