What are GI pipes and why are they important?
Galvanized Iron (GI) pipes are mild steel pipes coated with a protective layer of zinc.
This coating prevents rust and corrosion, making them strong, long-lasting, and reliable for transporting water, building structures, and more.
If you’re a contractor, plumber, or procurement manager, knowing which class of GI pipe to buy and how much it costs in 2025 can save both time and money.

How are GI pipes classified?
GI pipes are classified by wall thickness, which determines their durability and suitability for different uses.
| Class | Wall Thickness | Common Uses | Durability |
|---|---|---|---|
| Class A (Light) | Thinnest | Low-pressure water lines, temporary structures | Light-duty |
| Class B (Medium) | Medium | Residential plumbing, standard water supply | Medium-duty |
| Class C (Heavy) | Thickest | High-pressure, underground & industrial pipelines | Heavy-duty |
Tip: If your project is underground or high-pressure, choose Class C pipes for longer service life.
