Our ERW square/rectangular steel tubes are crafted from strip steel through advanced rolling and welding processes. Starting with the unwinding of strip steel, flattening, curling, and welding into round tubes, followed by rolling into square or rectangular shapes, is carefully controlled to ensure precise dimensions. These tubes are then cut to desired lengths to meet specific project requirements.
China Steel Pipe Group manufactures painted ERW steel pipes that meet the high standards of quality and environmental safety.
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.
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.
