Introduction
Raghav, a contractor, once faced an urgent supply deadline and realised how complex choosing the right gi pipe can be. His situation reflects the daily reality of many B2B buyers.
What a GI Pipe Is and Where Industries Use It
A gi pipe is mild steel coated with zinc, giving it corrosion resistance suitable for infrastructure work. Construction contractors use for water supply lines, scaffolding, structural frames, and fencing. Industrial fabricators depend on this for machinery frames, support structures, and mechanical assemblies. Plumbing companies also rely on this because it performs well under varying pressure levels and site conditions.
Across sectors—industrial projects, factories, commercial buildings, and public utilities—the gi pipe remains a preferred choice due to its durability, predictable performance, and availability in multiple sizes.
Price Comparison by Size and Class
GI pipe prices vary depending on nominal bore size, thickness class (A/B/C), and weight. Below is a reference table commonly used across the Indian B2B market:
| Size (NB) | Class | Approx Rate (₹/m) | Approx Weight (kg/m) |
|---|---|---|---|
| 25 mm | B | 130–140 | 2.9–3.0 |
| 40 mm | C | 200–215 | 3.5–3.6 |
| 50 mm | B | 215–230 | 5.3–5.5 |
| 100 mm | C | 500–520 | 16.0–16.3 |
These values reflect average market behaviour and may shift with supply conditions.

This illustrates how the gi pipe market often moves within a predictable price band.
What Affects GI Pipe Prices?
1. Raw Material Costs of gi pipe
Steel coil prices directly affect every this because weight contributes heavily to cost. When steel coil prices rise, gi pipe rates follow.
2. Zinc Coating Thickness
Heavier zinc coating improves the lifespan of this in outdoor and moisture-heavy conditions. As coating thickness increases, buyers see a cost rise.
3. Size, Class, and Weight
Class C pipes are the heaviest and cost more per meter. Larger diameters also push pricing upward.
4. Order Volume
Bulk orders of this pipe often unlock better per-kg prices. Smaller quantities tend to cost more per meter due to handling and logistics.
5. Location and Transportation
Long-distance transport and regional supply shortages can adjust pricing for this
Comparison With Alternatives
Many contractors compare this with other industrial pipe materials to plan budgets. Mild steel may sometimes appear cheaper, but it demands extra coating. Stainless steel offers superior corrosion resistance, and our previous blog on ss pipe helps buyers understand when stainless options make sense for specific high-exposure environments. Plastic pipes may win in lightweight applications, but this remains unmatched for structural, support, and heavy-duty installations.
How Udhhyog Supports B2B Buyers
At Udhhyog, we offer multiple sizes, classes, and specifications of gi pipe in one place, making procurement simpler for construction contractors, industrial fabricators, plumbing companies, and hardware traders. By maintaining reliable supply and offering competitive pricing, we help businesses source the right product without delays or inconsistent quality.
Conclusion
Choosing the right involves analysing application, size, class, and market factors rather than just focusing on the lowest price. By understanding the cost drivers and comparing alternatives, B2B buyers can make smarter, long-term procurement decisions. Are you ready to request your custom bulk quote today?
