GI Trunking

Heavy-duty GI Trunking designed for safe routing, protection, and organization of electrical and data cables in commercial, industrial, and infrastructure projects. Manufactured from galvanized iron (steel coated with zinc), these trunking systems provide superior strength, corrosion resistance, and long-term durability.

GI trunking is widely used where high mechanical protection and structured cable management are required, especially in factories, plant rooms, and large buildings.

Features & Benefits

• Heavy-Duty Metal Construction – Made from galvanized steel for maximum strength
• Corrosion Resistant – Zinc coating protects against rust and moisture
• Excellent Cable Protection – Shields cables from impact, dust, and damage
• Neat Cable Management – Organizes multiple cables in one enclosed system
• Fire Safety Advantage – Metal body helps reduce fire risk compared to plastic
• Removable Cover Design – Easy access for maintenance and future expansion

Materials & Care

Materials

GI trunking is made from steel coated with zinc (galvanization), which prevents corrosion and ensures long service life even in harsh environments.

Care & Handling

• Avoid damaging protective zinc coating
• Ensure proper earthing during installation
• Keep dry during storage
• Use correct supports and spacing
• Tighten covers properly for safety

Additional Details

• Preferred for heavy-duty cable protection and structured wiring systems
• Suitable for industrial plants, malls, hospitals, and commercial buildings
• Supports large cable capacity compared to conduits
• Allows easy modification and future cable additions
• Often used where PVC trunking is not strong enough
