Stainless Steel Perforated Cable Tray 304
BENDIN Stainless Steel Perforated Cable Tray 304 is a hygienic ventilated tray fabricated from AISI 304 / 316 stainless steel. It is polished for food, pharmaceutical and marine areas where rust-free, easy-clean cable support is mandatory.
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: stainless steel 304 / 316 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
Food and beverage factories.
Pharmaceutical and clean rooms.
Marine and offshore projects.
Chemical plants.
Coastal power and water projects.
BENDIN Types & Material Specifications:
Classified by stainless steel grade and load capacity, with 304 for general corrosion resistance and 316L for coastal and chemical sites.
1. 304 Stainless Steel Perforated Cable Tray: general corrosion resistance for humid, low-salt environments.
2. 316L Stainless Steel Perforated Cable Tray: superior chloride and salt spray resistance for coastal and offshore sites.
3. Duplex Stainless Steel (2205/2507): for highly corrosive heavy industry and offshore high-load projects.
4. Light-Duty Perforated Tray: thin plate for instrument and low-voltage control cables.
5. Heavy-Duty Perforated Tray: thicker plate and reinforced rails for heavy power cables.
6. Perforated Tray with Divider: internal separators for power and signal cables.
Accessories include stainless steel splice plates, brackets, expansion joints, end caps and cover plates.
Global Certification & Standard Requirements and Common Specifications Table:
| Region / Standard System | Main Certification & Standard | Requirements for Stainless Steel Perforated Cable Tray 304 | 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 100-1200 mm; side height 50-150 mm; thickness 1.2-3.0 mm; standard length 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 100-1200 mm; side rail height 50-150 mm; thickness 1.2-3.0 mm; 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 100-1200 mm; thickness 1.2-3.0 mm; standard length 3m / 6m |
| Australia & New Zealand | AS/NZS 3012 | Specifies mechanical strength and corrosion aging tests for industrial cable support systems. | AISI 304 / 316 Stainless 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. | AISI 304 / 316 Stainless 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 stainless steel 304 / 316 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 Stainless Steel Perforated Cable Tray 304 provides hygienic, rust-free and ventilated cable support for food, pharmaceutical and marine installations.
