Galvanized Perforated Cable Tray with Cover
BENDIN Galvanized Perforated Cable Tray with Cover is a hot dip galvanized ventilated tray supplied with a full enclosure cover. The cover shields cables from dust, impact and water, while the perforated base provides heat dissipation for indoor and sheltered outdoor installations.
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: pre-galvanized and hot dip galvanized steel 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 full enclosure cover guards cables against dust, debris, water and mechanical damage.
Typical Application Scenarios
Commercial and industrial buildings.
Data and telecommunication rooms.
Manufacturing workshops and warehouses.
Power distribution corridors.
Sheltered outdoor cable routes.
BENDIN Types & Material Specifications:
Manufactured in Q235 cold rolled steel hot dip galvanized, with full enclosure cover and widths from 50mm to 1000mm.
1. Pre-Galvanized (GI) Perforated Cable Tray: zinc coated for general indoor and sheltered use.
2. Hot Dip Galvanized Perforated Cable Tray: thicker zinc layer for outdoor and humid industrial sites.
3. Solid Bottom GI Perforated Cable Tray: closed base to stop dust and small debris.
4. GI Perforated Tray with Cover: matching lid for extra cable protection.
5. Heavy-Duty GI Perforated Tray: reinforced rails for long spans and heavy loads.
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 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 50-1000 mm; side height 50-250 mm; thickness 1.0-2.5 mm; standard length 2.44m / 3.0m |
| 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 50-1000 mm; side rail height 50-250 mm; thickness 1.0-2.5 mm; 2.44m / 3.0m standard length |
| China | GB/T 23639, GB/T 10216, CCC (fire-rated option) | GB/T 23639 governs the mechanical performance of cable trays; CCC certification is required for fire-resistant versions on large projects. | Width 50-1000 mm; thickness 1.0-2.5 mm; standard length 2.44m / 3.0m |
| Australia & New Zealand | AS/NZS 3012 | Specifies mechanical strength and corrosion aging tests for industrial cable support systems. | Q235 Hot Dip Galvanized Steel; support span up to 3 m |
| International Oil & Chemical Industry | API Standard, ISO 9227 | API standard for petrochemical refineries; ISO 9227 salt spray test for material qualification, normally project specified. | Q235 Hot Dip Galvanized Steel; heavy duty sections, support span up to 3 m |
BENDIN Installation & Selection Considerations
1. Material and Surface Selection: evaluate the corrosive media on site and confirm pre-galvanized and hot dip galvanized steel 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 Galvanized Perforated Cable Tray with Cover combines HDG corrosion protection, ventilated heat dissipation and a full enclosure cover for clean, protected cable routing.
