Introduction to GI Gratings
GI Gratings, also known as Galvanized Iron Gratings, are durable and corrosion-resistant steel structures used for flooring, platforms, stair treads, walkways, and drainage covers. Manufactured using mild steel and galvanized with a protective zinc coating, these gratings offer superior strength, slip resistance, and long-term performance in industrial, commercial, and infrastructure projects. Their open grid design ensures excellent load-bearing capacity, ventilation, and drainage, making them a trusted choice across multiple industries.
Manufacturing Process of GI Gratings
GI Gratings are fabricated from mild steel flat bars and cross bars through welding or pressure-locking methods. Once assembled, the gratings undergo hot-dip galvanization as per IS/ASTM standards, ensuring long-lasting resistance against rust, moisture, and harsh weather conditions. The galvanizing process creates a protective zinc coating that bonds strongly with the steel surface, extending service life and reducing maintenance requirements for heavy-duty industrial applications.
Types of GI Gratings
- Electroforged Welded GI Gratings – strong and widely used for industrial flooring and platforms.
- Press-Locked GI Gratings – precise and uniform with high dimensional accuracy.
- Heavy Duty GI Gratings – designed for truck terminals, loading bays, and airports.
- Serrated GI Gratings – slip-resistant design for enhanced workplace safety.
- Custom Fabricated GI Gratings – tailored shapes, sizes, and load capacities.
