Page Content

Standard cable tray thicknesses in ASEAN typically range from 1.0 mm to 2.0 mm, depending on material and application.

Standard Thickness Ranges

Cable trays manufactured in ASEAN countries, including Vietnam, Indonesia, and Thailand, generally follow international fabrication standards such as BS EN 61537:2023, NEMA, and IEC. Typical thicknesses for steel cable trays are 1.0 mm, 1.2 mm, 1.5 mm, and 2.0 mm, with variations depending on the material type—pre-galvanized steel, hot-dip galvanized steel, stainless steel, or aluminum . Material thickness directly affects load-bearing capacity, allowable span, and long-term durability .

Material Considerations

  • Steel trays: Most common, available in pre-galvanized, hot-dip galvanized, or stainless steel. Thickness ranges from 1.0 mm to 2.0 mm, with thicker trays used for heavy-duty applications or long spans .
  • Aluminum trays: Lightweight and corrosion-resistant, typically used in environments where steel may corrode. Thickness is usually comparable to steel for similar load ratings .
  • Wire mesh or basket trays: Thickness is defined by wire diameter rather than sheet thickness, but structural performance depends on wire gauge and support spacing .

Compliance and Installation

ASEAN cable trays are designed to meet international standards for safety, heat dissipation, and electromagnetic interference (EMI) mitigation. Proper thickness ensures that trays can support the intended cable load without excessive deflection, maintain spacing for signal and power cables, and comply with installation codes .

Practical Selection Tips

  1. Determine cable load: Heavier power cables require thicker trays.
  2. Consider span length: Longer unsupported spans need thicker or reinforced trays.
  3. Account for environmental conditions: Corrosive environments may require stainless steel or thicker galvanized trays.
  4. Check standards compliance: Ensure trays meet IEC, NEMA, or local ASEAN equivalents for structural and electrical safety . In summary, ASEAN cable trays typically use 1.0–2.0 mm thickness for steel and aluminum trays, with the exact choice depending on load, span, and environmental conditions, while always adhering to international and regional standards.
