ERW
STEEL TUBES
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.
