As of September 2026, JSW GI pipe prices in India have recovered to roughly ₹103 per metre for 15 mm light-class pipe and about ₹2,009 per metre at the 200 mm heavy-class end, a net list increase of close to 3% since July. JSW GI Pipes have emerged as a trusted name in the galvanised iron pipe industry, offering unparalleled quality and versatility. Whether you're a contractor, builder, or homeowner, understanding the specifications, pricing, and applications of JSW GI Pipes can help you make informed decisions for your projects. This comprehensive guide delves deep into every aspect of JSW GI Pipes, ensuring you have all the information you need.

Overview of JSW Steel and GI Pipes

JSW Steel Pipes Limited is a flagship company of the JSW Group, one of India's most diversified conglomerates with a significant presence in various sectors, including steel, energy, infrastructure, cement, and sports. Established in 1982, JSW Steel has grown exponentially to become one of India's leading integrated steel manufacturers, with a steel-making capacity of over 28 million tons per annum (MTPA).

Operates state-of-the-art manufacturing facilities across India, equipped with the latest technology for steel production and processing. These facilities adhere to stringent quality control measures, ensuring that every product—including JSW Steel Sheets, JSW TMT Bars, and JSW GI Pipes—meets international standards.

JSW GI Pipes, a flagship product in the company's portfolio alongside JSW Steel Sheets and JSW TMT Bars, are galvanised iron pipes that have been treated with a uniform zinc coating through the hot-dip galvanization process. This process involves immersing the steel pipes in molten zinc at a temperature of around 450°C, resulting in a robust zinc-iron alloy layer that provides exceptional resistance to corrosion. The galvanization not only enhances the pipes' durability but also extends their service life, making them ideal for a wide range of applications. Zinc has done most of the work on price this quarter: net list rates on galvanised tube are up roughly 3% since July, while flat steel stayed rangebound behind the 11.5% safeguard duty on HS 7208 to 7212, 7225 and 7226 and long products fell through the monsoon.

Frequently Asked Questions (FAQ)

1. How do IS 1239 and IS 3589 differ for pipes?
   IS 1239 covers screwed and socketed black and galvanised tube up to 150 mm nominal bore, while IS 3589 covers larger welded pipe from 168 mm upward for water, gas and slurry mains.
2. How does a per-kg GI rate translate into the per-metre prices listed above?
   Multiply the rate per kg by the kg-per-metre weight shown in that row, so 25 mm heavy-class pipe at 3.3 kg/m and about ₹69 per kg lands near ₹228 per metre.
3. Does the listed per-metre price cover delivery and threading?
   No, GI pipe is quoted ex-stockyard in standard lengths, with freight, cutting and threading charged separately and 18% GST added on top.
4. Where do SS 304, SS 202 and SS 316 sit against GI on corrosion resistance?
   GI depends on a sacrificial zinc coat, SS 202 is the cheapest stainless option and suits dry indoor duty, SS 304 handles general water and food-contact service, and SS 316 adds molybdenum for coastal and chemical exposure.
5. Weathering steel needs no paint, so why does GI still need a zinc coating?
   Weathering steel is alloyed with copper, chromium and nickel so it forms a stable protective patina, whereas plain carbon pipe has no such self-protection and relies on the hot-dip zinc layer instead.
