Chhajed Steel Limited is devoted to fulfilling each and every expectation of our Business partners. We design and manufacture Ductile iron Spun Pipes. The Ductile Iron Spun Pipes are made from ductile iron. Ductile iron is known for their high tensile strength, ductility, corrosion and impact resistance. These are low carbon protected pipes, widely used in Industries.

Ductile iron Spun Pipes are generally is manufactured using centrifugal casting in metal or resin lined moulds. Ductile iron pipings are used in utility projects such as water and sewer. If we focusing on its strength, recyclability and life-cycle cost, it provides an alternative to PVC. A ductile iron pipe is normally manufactured exclusively from recycled material. The pipe can be recycled after use. They are one of the contributors to Sustainable development.

Chhajed Steel Limited provides you with user-specific pipes at a very competitive rate.
