Ashtapad Overseas Ashtapad Overseas
We manufacture & export ERW steel pipes that are available in various qualities, wall thicknesses and diameters of the finished pipes. While manufacturing ERW steel pipes only high-quality, continuous-cast, fully killed, control-rolled, fine-grain, low-carbon steel is used. High performance ERW steel pipes and tubing possess high strength corrosion resistance, higer deformability, better strength and toughness.
