What is Cable Trunking? Complete Guide for Commercial & Industrial Projects

What is Cable Trunking?

Cable trunking is an enclosed or semi-enclosed channel system used to carry electrical, data, communication, and control cables. It is commonly manufactured from GI steel, galvanized steel, stainless steel, aluminium, GRP, or other project-suitable materials.

Unlike open cable trays, cable trunking provides better cable enclosure and protection, making it suitable for areas where cables need to be concealed, secured, or protected from external impact.

At Metar, cable trunking systems are designed for commercial, industrial, and infrastructure projects requiring reliable cable routing and protection.

Why Cable Trunking is Used in Electrical Installations

Cable trunking systems are used to improve cable safety, organization, and accessibility across different project environments.

Main Benefits of Cable Trunking

• Protects cables from physical damage
• Improves cable organization
• Supports neat and professional installations
• Allows easier maintenance and cable replacement
• Reduces cable exposure in commercial areas
• Supports electrical, data, and communication wiring

Common Types of Cable Trunking Systems

1. GI Cable Trunking

GI cable trunking is made from galvanized steel and is widely used in commercial and industrial electrical installations. It offers good durability, practical corrosion resistance, and cost-effective cable protection.

2. HDG Cable Trunking

HDG cable trunking is hot dip galvanized for better corrosion protection. It is commonly used in outdoor, industrial, and infrastructure projects where environmental exposure is higher.

3. Steel Cable Trunking

Steel cable trunking provides strong mechanical protection and is suitable for heavy-duty electrical installations.

4. Aluminium Cable Trunking

Aluminium cable trunking is lightweight, corrosion-resistant, and suitable for commercial buildings, offices, and selected industrial applications.

5. GRP Cable Trunking

GRP cable trunking is used in corrosive environments such as chemical plants, water treatment facilities, marine projects, and industrial areas exposed to moisture or chemicals.

6. Underfloor Cable Trunking

Underfloor cable trunking is installed below raised floors or floor systems to route electrical, data, and communication cables in offices, data centers, and commercial buildings.
