Hot Dip Galvanized Perforated Cable Tray with Cover
BENDIN Hot Dip Galvanized Perforated Cable Tray with Cover is a heavy-duty galvanized tray supplied with a protective lid for the 50mm to 900mm width range. The hot dip galvanized finish delivers long-term corrosion protection, and the cover shields cables from dust and impact for demanding indoor and outdoor use.
Application and Functions in Different Scenarios
Core Functions
1. Efficient Heat Dissipation: the perforated base releases heat generated by loaded power, control and instrument cables, preventing overheating and extending cable service life.
2. Corrosion Protection: hot dip galvanized steel to ASTM A123 resists humidity, salt spray and industrial fumes so the tray stays reliable in demanding environments.
3. Organized Cable Routing: the channel separates power cables from signal cables, reducing electromagnetic interference to sensitive control instruments.
4. Fast Installation and Maintenance: the open perforated design allows quick cable laying, inspection, drop-out and later system expansion without complex civil work.
5. Added Cable Protection: the matching cover guards cables against dust, debris and mechanical damage.
Typical Application Scenarios
Outdoor and coastal industrial sites.
Power plants and substations.
Petrochemical and heavy industry.
Rail and infrastructure projects.
Dusty or exposed cable routes.
BENDIN Types & Material Specifications:
Produced in carbon steel hot dip galvanized to ASTM A123, with lid, custom widths and support spans from 1.5m to 9m.

2. Heavy-Duty HDG Perforated Tray: thick plate and reinforced rails for heavy power cables.
3. Medium-Duty HDG Perforated Tray: balanced strength for general infrastructure.
4. HDG Tray with Cover: matching lid for dust and impact protection.
5. HDG Solid Bottom Perforated Tray: closed base for dusty environments.
6. Custom Bends, Tees and Reducers: fabricated to the project layout.
The complete system includes perforated straight sections plus covers, splice plates, brackets, elbows, tees and end caps.
Global Certification & Standard Requirements and Common Specifications Table:
| Region / Standard System | Main Certification & Standard | Requirements for Hot Dip Galvanized Perforated Cable Tray with Cover | Common Specifications |
|---|---|---|---|
| North America | NEMA VE1, NEMA VE2, UL, CSA C22.2 No.126.1, NEC Article 392 | NEMA VE1 defines the mechanical load test; UL covers fire resistance and CSA is required for Canadian projects. Corrosion and load deflection tests must be passed. | Width 50-900 mm; side height 50-250 mm; thickness 1.0-2.5 mm; standard length 2.4m / 3m |
| European Union | IEC 61537, BS EN 61537, CE Marking | IEC 61537 is the core international standard for cable tray systems; CE marking is mandatory for the EU market, with corrosion aging and mechanical load testing for industrial projects. | Width 50-900 mm; side rail height 50-250 mm; thickness 1.0-2.5 mm; 2.4m / 3m standard length |

| International Oil & Chemical Industry | API Standard, ISO 9227 | API standard for petrochemical refineries; ISO 9227 salt spray test for material qualification, normally project specified. | Hot Dip Galvanized Steel; heavy duty sections, support span 1.5-9 m |
BENDIN Installation & Selection Considerations
1. Material and Surface Selection: evaluate the corrosive media on site and confirm hot dip galvanized steel to ASTM A123 with the correct surface treatment before ordering.
2. Avoid Galvanic Corrosion: never let dissimilar metals touch directly; use matching bolts and insulating gaskets between the tray and carbon steel brackets.
3. Load Calculation and Support Span: calculate the total cable weight to select the correct plate thickness and load class, and reduce the support span where heavy cables concentrate.
4. Thermal Expansion Control: install expansion joints on long straight runs to absorb thermal deformation caused by temperature changes.
5. Continuous Earthing and Bonding: keep continuous electrical bonding across all metal sections, mandatory in hazardous classified zones.
6. Separation of Power and Instrument Cables: use dividers to separate power cables from instrument cables and cut electromagnetic interference.
7. Cutting and Re-Protection on Site: cut with the correct tools and re-protect every cut edge and weld so the corrosion-resistant surface is restored.
8. Surface Inspection Before Installation: check the coating before installation, protect the surface during transport and repair any scratches that expose bare metal.
BENDIN Hot Dip Galvanized Perforated Cable Tray with Cover combines durable HDG corrosion protection and a matching lid for clean, protected cable routing.
