Sri Lanka Standard Cable Tray Specifications

Cable trays in Sri Lanka are available in various materials, finishes, and configurations, designed to meet industrial, commercial, and architectural requirements while complying with international standards.Materials and Finishes

Cable trays are manufactured from a range of materials to suit different environments and load requirements:

• Mild Steel: Often zinc-coated or hot-dip galvanized for corrosion resistance .
• Stainless Steel: Provides high durability and resistance to harsh environments .
• Aluminum and Aluzinc: Lightweight, corrosion-resistant options suitable for indoor and outdoor use .
• Powder-Coated Steel: Offers aesthetic appeal and additional corrosion protection, ideal for indoor installations .

Types of Cable Trays

• Ladder Type: Consists of two side rails connected by rungs, providing maximum ventilation for heat-producing cables such as power cables .
• Solid Bottom: Constructed from a single sheet of metal, offering excellent protection for control, communication, and non-heat-producing cables .
• Perforated or Ventilated Trays: Allow air circulation to dissipate heat while protecting cables from physical damage .
• Modular Systems: Such as TrayMax™ TM-TRYS, designed for flexible routing, easy expansion, and robust load-bearing capacity .

Dimensions and Load Capacity

• Tray widths and heights vary depending on cable volume and load requirements, with common straight lengths ranging from 100mm x 50mm to larger industrial sizes .
• Sheet thickness typically ranges from 0.8 mm to 3.0 mm, selected based on span, load, and application .
• Accessories include bends, tees, reducers, supports, couplers, and lids for secure installation and long-term reliability .

Standards and Compliance

• Many Sri Lankan cable trays comply with EN 61537 for cable tray systems and EN ISO 1461 for hot-dip galvanization, ensuring durability and corrosion resistance .
• Local brands like GERSAN and CEYLEKTRA provide hot-dip galvanized and powder-coated trays that meet international standards for industrial and commercial applications .

Applications

• Suitable for industrial plants, commercial buildings, data centers, power stations, and utility infrastructure .
• Provide organized, safe, and efficient cable management, protecting cables from physical damage, fire, and environmental exposure .
• Customizable in various RAL colors for aesthetic integration in architectural projects .
