Spiral welded steel pipes are produced by spirally winding a steel strip at a predetermined angle, forming a tube that is welded along the seam. This method allows the use of narrower strips to manufacture large diameter pipes, offering a cost-effective solution for various industrial applications.
ERW pre-galvanized steel pipes, also known as mill galvanized pipes, are recognized for their bright, smooth, and aesthetically pleasing appearance.
Our ERW round steel pipes are longitudinally welded pipes that are manufactured by forming steel strip into hollow shape, and then welded along the length of the steel pipe.
Seamless steel pipes are manufactured by thrusting a piercing mandrel through a steel billet to form a hole, then processed by a rolling mill to a specified diameter and wall thickness.
China Steel Pipe Group offers a wide array of prestressing strands (PC Strand), twisted steel cable composed of high strength steel wires, available in both bonded and unbonded types, designed to significantly enhance the reinforcement of prestressed concrete structures.
