When it comes to construction, fabrication, or infrastructure development, the type of steel pipe you select can make or break your project. Not all pipes are created equal — especially when it comes to choosing between MS (Mild Steel), GI (Galvanised Iron), and GP (Pre Galvanised) pipes. Each comes with distinct features, applications, and advantages as per their characteristics.
In this guide, we’ll break down the differences between these three pipe types to help you make you select an informed, performance-driven choice.
MS Pipes are made from low carbon steel, enabling them easy to weld and form/mold. Their high tensile strength and ductility make them the backbone of structural and industrial projects.
Key Features:
Typical Applications:
Why Choose MS Pipes?
If you're building heavy-duty structures or require flexibility in shaping and welding, MS Pipes will provide unmatched strength and affordability.
GI Pipes are essentially MS Pipes coated with zinc to resist corrosion and enhance longevity, especially in outdoor or water-based applications.
Key Features:
Typical Applications:
Why Choose GI Pipes?
GI pipes are ideal when exposed to moisture or corrosive environments is a concern. The zinc coating offers a protective layer, extending the pipe's life even in harsh climates and underground applications.
GP Pipes are manufactured using cold-rolled coils (CRCA) and then galvanised to achieve a smooth, uniform finish with excellent corrosion resistance.
Key Features:
Typical Applications:
Why Choose GP Pipes?
When appearance matters alongside strength and corrosion resistance, GP Pipes shine — quite literally. Their smooth surface makes them suitable for interiors, consumer products, and exposed installations.
| Feature | MS Pipes | GI Pipes | GP Pipes |
|---|---|---|---|
| Corrosion Resistance | Low | High (zinc coating) | High (uniform galvanisation) |
| Surface Finish | Matte / Raw | Matt / Coated | Smooth, bright |
| Best For | Structural use | Water & plumbing, fencing | Interiors, modular, fabrication |
| Cost | Most economical | Slightly higher, value for finish | Moderate |
| Fabrication Friendly | Yes | Moderate | Excellent |
| Welding Capability | Excellent | Can require care (coating) | Excellent |
