Our manufacturing facility spans over 100,000 square meters and houses more than 20 production lines, employing a dedicated team of 360 professionals. With an annual production capacity of 500,000 tons, we are well-equipped to meet the demands of the steel pipes and PC strand industry. Our advanced equipment includes automated welding pipe production lines, high-precision cutting machines, and intelligent welding machines, all designed to enhance production efficiency and ensure the highest quality and precision in our welded pipe products.
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. Through the high-frequency electric resistance welding (ERW) process, this type of round steel pipes yields strong joints due to the heat from the electric current can deeply penetrate the metal material. This makes the steel pipe durable and highly customizable, having a wide variety of structural, architectural and construction applications.
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.
ERW hot-dip galvanized steel pipes come in two main types: pre-galvanized and hot-dip galvanized. The hot-dip galvanizing process enhances the pipes' corrosion resistance and extends their lifespan, making them a top choice for applications in construction, machinery, bridges, agricultural and oil machinery, and mining industry.
China Steel Pipe Group offers oil coated ERW steel pipes, a specialized option that undergoes a surface treatment with low-viscosity, environmentally-friendly anti-rust oil. This protective oil coating significantly reduces the risk of corrosion, thereby extending the operational lifespan of the pipes under various environmental conditions.
China Steel Pipe Group manufactures painted ERW steel pipes that meet the high standards of quality and environmental safety. Using innovative spray equipment and advanced painting techniques, which include precise control of spray distance, pressure, speed, and angle, we ensure our painted pipes offer exceptional thickness, gloss, smoothness, and adhesion. Our choice of high-quality, eco-friendly paints adheres to national and international standards, providing a finish that stands out in any engineering and usage environment.
ERW pre-galvanized steel pipes, also known as mill galvanized pipes, are recognized for their bright, smooth, and aesthetically pleasing appearance. These pipes are coated with a thinner layer of zinc compared to traditional galvanized steel, making them a cost-effective solution for various applications. Despite the lighter zinc coating, they still offer adequate protection against corrosion.
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.
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. Formed from a single piece of steel, this process ensures the pipe's strength, structural integrity and uniformity.
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. PC strands are essential in fortifying large-span railway and highway bridges, major bridges, silos, buildings, dams, floor slabs, foundations, large concrete vessels, crane beams, anchorages, multi-storied industrial buildings, and more.
Manufactured using sophisticated continuous hot strip mills, hot-rolled steel coils are known for their excellent formability and weldability. These steel coils can be used to form the base products like coated and galvanized coils, and serve as a basic material for producing steel pipes, wires, sheets, etc. This versatility makes them ideal for foundational materials in manufacturing diverse components across industries.
