Gi Perforated Cable Tray 300mm
BENDIN Gi Perforated Cable Tray 300mm is a galvanized ventilated cable support with a 300mm wide perforated base. It balances corrosion resistance and heat dissipation at an economical cost, making it a practical choice for general industrial, commercial and infrastructure cable routing.
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. Mechanical Strength and Safety: reinforced side rails support heavy cable loads and provide continuous metal bonding for earthing.
Typical Application Scenarios
Industrial workshops and manufacturing plants.
Commercial buildings and shopping centers.
Power distribution rooms and electrical substations.
Data and telecommunication rooms.
Infrastructure and utility corridors.

Global Certification & Standard Requirements and Common Specifications Table:
| Region / Standard System | Main Certification & Standard | Requirements for Gi Perforated Cable Tray 300mm | 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 50-150 mm; thickness 1.0-3.0 mm; standard length 2m / 3m / 6m |
| 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 50-150 mm; thickness 1.0-3.0 mm; 2m / 3m / 6m 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 1.0-3.0 mm; standard length 2m / 3m / 6m |
| Australia & New Zealand | AS/NZS 3012 | Specifies mechanical strength and corrosion aging tests for industrial cable support systems. | 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. | 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.
