Key Price Movement Observations
During the first quarter of 2025, prices remained on the higher side due to strong demand from construction and infrastructure projects. From April to August, the market saw a gradual softening as raw material prices stabilized and monsoon-season demand slowed down. In the last quarter, prices showed mild recovery driven by festive-season buying, government projects, and restocking by dealers.
Heavy-class GI pipes consistently stayed at the upper end of the price range due to higher wall thickness and increased zinc coating weight, while light-class pipes remained more economical.
Factors Affecting 3-Inch GI Pipe Prices
Several factors influence monthly price changes of GI pipes:
• Steel coil and billet price movement
• Zinc coating cost and coating thickness
• Pipe class (Light, Medium, Heavy)
• Manufacturing standards and certification
• Transportation and regional availability
• Seasonal construction demand
Even small changes in raw material pricing can impact GI pipe rates on a month-to-month basis.
