Stainless Steel Perforated Cable Tray
BENDIN Stainless steel perforated cable tray is a ventilated cable management system fabricated from stainless steel plates with regularly punched holes on the tray base. Combining excellent corrosion resistance and good heat dissipation performance, it is widely used in harsh industrial environments where ordinary carbon steel cable trays cannot survive. Its perforated base design allows efficient heat dissipation of power, control and instrument cables, while the stainless steel material resists moisture, salt spray, acid and alkali vapors. It provides stable mechanical support for cables, protects wiring from environmental damage, simplifies inspection and maintenance, and ensures continuous, safe power and signal transmission for industrial facilities.
Application and Functions in Different Scenarios
Core Functions
1. Efficient Heat Dissipation: The perforated structure dissipates heat generated by loaded cables, preventing cable overheating and extending cable service life.
2. Corrosion Protection: Stainless steel resists salt, chemical vapors, humidity and airborne contaminants, ideal for corrosive working conditions.
3. Organized Cable Routing: Separates power cables and signal cables, reducing electromagnetic interference for precision control instruments.
4. Easy Installation & Maintenance: Open perforated base enables quick cable laying, inspection, replacement and system expansion without complex civil work.
5. Mechanical Strength & Safety: High tensile strength supports heavy cable loads; continuous metal structure meets earthing requirements for hazardous industrial zones.
Typical Application Scenarios
Chemical & Petrochemical Plants: Used in reaction workshops, chemical piping corridors and waste treatment areas exposed to acid/alkali vapor.
Offshore & Marine Projects: Offshore platforms, coastal power substations with heavy salt spray corrosion.
Water & Wastewater Treatment Plants: Sewage treatment workshops, desalination plants with humid and corrosive fumes.
Pharmaceutical & Food Factories: Clean production workshops requiring sanitary, rust-free cable support systems.
Power Industry: Substations, power plants, new energy solar and wind farm projects in coastal or high-humidity regions.
Underground Tunnels & Mining: Underground industrial tunnels with high humidity and mineral corrosive dust.
BENDIN Types & Material Specifications:
Stainless steel perforated cable tray is classified mainly by stainless steel grade, load capacity and accessory configuration:
1. 304 Stainless Steel Perforated Cable Tray: General corrosion resistance, suitable for humid, low-salt, mild corrosive industrial environments.
2. 316L Stainless Steel Perforated Cable Tray: Superior resistance to chloride, salt spray and acid vapors, preferred for coastal, offshore and strong corrosive chemical sites.
3. Duplex Stainless Steel (2205/2507) Perforated Tray: For extreme corrosive heavy industrial and offshore high-load projects.
4. Light-Duty Perforated Tray: Thin plate, for instrument & low-voltage control cables, short support spans.
5. Heavy-Duty Perforated Tray: Thicker stainless steel plate, reinforced side rails, for heavy power cables and long support spans.
6. Perforated Tray with Divider: Internal separators to isolate high-voltage power cables and low-voltage signal cables.
Accessories include stainless steel splice plates, brackets, expansion joints, end caps, wall brackets and cover plates.

BENDIN Installation & Selection Considerations
1. Material Grade Selection: Evaluate corrosive media on site. Select 316L or duplex stainless steel for chloride-rich, salt spray and strong acid environments; 304 is enough for mild humid environments.
2. Avoid Galvanic Corrosion: Prevent direct contact between stainless steel and carbon steel. Use stainless steel bolts and insulating gaskets between stainless tray and carbon steel brackets to avoid galvanic corrosion.
3.Load Calculation & Support Span: Calculate total cable weight to select proper plate thickness and load class. For heavy cables, reduce support span to avoid deflection.
4. Thermal Expansion Control: Install expansion joints for long straight runs to absorb thermal deformation caused by temperature fluctuation.
5. Continuous Earthing & Bonding: Keep continuous electrical bonding for all metal sections. Proper earthing is mandatory for hazardous classified Ex zones in chemical plants.
6. On-site Cutting & Welding: Use dedicated cutting tools for stainless steel. Any welding on site must be polished and acid passivated to restore the anti-corrosion passive film.
7. Separation of Power and Instrument Cables: Use internal dividers to separate power cables and instrument cables to reduce electromagnetic interference.
8. Inspect Surface Condition: Check surface passivation layer before installation. Protect tray surface during transportation and installation; repair scratches that damage the passive film.
