The DI Pipe business is the newest and the most aggressive entrant to the business stable of Rashmi Metaliks. The last 4 years have been very fulfilling and have returned a CAGR of 62%.
We produce Ductile Iron Pressure Pipes as per ISO 8329:2000 which has not only helped us maintain excellent standards of production but has also made us reach the pole position in the market.
With our hard work and utmost dedication, we have upgraded our production to 7,70,000 Metric Tonnes of DI Pipes annually.
What veins and arteries are to humans is what DI Pipes are to the modern civilizations. As cities, towns and villages grow, transporting water for human consumptions from its source is a growing challenge.
It is here that the range of high tensile strength, corrosion resistant and durable DI Pipes from the Rashmi Metaliks find their usefulness.
The DI Pipe from the Rashmi Metaliks stable is made in a state of the art and integrated plant located at Kharagpur, West Bengal. The plant is able to greatly control the quality of the DI Pipes as it has vertically integrated all its processes, including putting up its own:
The A+ grade quality of DI Pipe is manufactured in a wide range of application – from DN 100 to DN 1200. The state-of-the-art plant has invested and shall stay invested in upgrading its technology so as to deliver quality products to its Domestic and International clients.
