Tunisian ladder-type cable tray models and specifications

Ladder-type cable trays are available in various materials, widths, and thicknesses, designed to support power and control cables with high structural integrity and ventilation.Construction and Design

Ladder-type cable trays consist of two longitudinal side members connected by transverse rungs, providing open support for cables and allowing air circulation to prevent overheating . The rungs are typically welded or mechanically fastened to the side rails, ensuring maximum structural strength and stability . Some models include Ty-Rap® slots for easy cable fastening and adjustable barrier strips .

Materials

Common materials for ladder trays include:

  • Aluminum: Lightweight, corrosion-resistant, suitable for indoor and outdoor use .
  • Steel: Standard or hot-dip galvanized for enhanced corrosion protection .
  • Stainless Steel (AISI 316): High corrosion resistance, ideal for harsh environments .
  • PVC-coated Aluminum or Steel: Provides additional chemical and moisture protection .
Dimensions and Thickness
  • Width: 100 mm to 1500 mm, typically in 50 mm increments .
  • Height: 50 mm, 70 mm, 100 mm, 120 mm, depending on load requirements .
  • Thickness: 3 mm to 8 mm, selected based on support span and loading details .
  • Rung spacing: Usually 1” centers for cable tie compatibility .
Surface Treatment
  • Pre-galvanized steel: Coated before fabrication, suitable for indoor applications .
  • Hot-dip galvanized: Thicker coating for outdoor or industrial environments .
  • Bare steel: For indoor use where corrosion is not a concern .
Fittings and Accessories

Ladder trays can be complemented with a variety of fittings to accommodate complex cable routing:

  • Elbows (horizontal and vertical)
  • Reducers
  • Tees and crosses
  • Joint connectors and cover clips
Standards and Compliance

Ladder-type cable trays generally conform to:

  • ANSI/NFPA 70 (National Electrical Code)
  • NEMA VE 1-2017 (Metal Cable Tray Systems)
  • ASTM A123 & ISO 1461 for galvanization and corrosion protection
Applications

These trays are suitable for:

  • Industrial plants, power generation facilities, and commercial buildings
  • Supporting power, control, and communication cables
  • Environments requiring ventilation and easy cable access for maintenance By selecting the appropriate material, width, thickness, and surface treatment, ladder-type cable trays can be tailored to meet the specific requirements of Tunisian electrical installations, ensuring compliance with international standards and long-term durability.
