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.
