What is GI Cable Trunking?

GI cable trunking is manufactured using galvanized steel material designed to provide organized and protected cable routing for commercial and industrial electrical installations.

GI trunking is commonly used for indoor projects where moderate corrosion resistance and cost-effective cable protection are required.

At Metar, GI cable trunking systems are supplied for commercial, industrial, and infrastructure applications across UAE.

Advantages of GI Cable Trunking

  • Cost-effective cable management solution
  • Good mechanical protection
  • Suitable for indoor installations
  • Strong structural support
  • Widely used in commercial projects

What is HDG Cable Trunking?

HDG cable trunking is manufactured using a hot dip galvanization process where fabricated steel trunking sections are immersed into molten zinc after fabrication.

This process creates a thicker zinc coating that improves corrosion resistance and long-term durability.

HDG cable trunking is widely used in outdoor and industrial environments exposed to moisture, humidity, and harsh weather conditions.
