Galvanized Square Tube
Galvanized square tubes are made from hot-rolled or cold-rolled galvanized steel strip or galvanized coil, cold-bent into shape, and then high-frequency welded. They are also made from cold-bent hollow steel tubes and hot-dip galvanized. They have a square cross-section.

Hot-dip galvanized square tubes: Steel plates or strips are rolled and welded into square tubes, then placed in a hot-dip galvanizing bath for a chemical reaction. The production process is simple, efficient, and offers a wide range of specifications, requiring less equipment and capital. However, the strength is lower than that of seamless square tubes.
• Strong corrosion resistance: Zinc forms dense quaternary crystals, effectively blocking corrosion factors. On damaged areas, such as cut edges, the zinc forms an oxide layer for further protection.
• Excellent mechanical properties: Retains the original steel's high strength and toughness, capable of withstanding significant pressure and tension.
• Beautiful appearance: The surface is smooth with a silvery-white metallic luster. Applications
Widely used in curtain walls, building structures, machinery manufacturing, steel construction, shipbuilding, solar panels, steel structure engineering, power engineering, agricultural and chemical machinery, glass curtain walls, automobile chassis, airport facilities, and also in furniture, sports equipment, display stands, outdoor billboards, street lights, traffic signs, guardrails, and spare parts.

Cold-Rolled Seamless Steel Pipe
Seamless steel pipe is a kind of steel pipe with a hollow cross section, seamless periphery and long length.
Production Process: Manufactured by cold rolling. Cold-rolled seamless steel pipe is a hot-rolled pipe that undergoes further processing, such as cold drawing or cold rolling, to improve its dimensional accuracy and surface quality.
Features
• High Strength: Withstands high pressure and stress, suitable for high-pressure, high-temperature applications.
• Good Sealing: The lack of welds reduces leakage and other issues, resulting in high reliability.
• Excellent Surface Quality: The smooth surface of cold-rolled seamless steel pipe reduces resistance during fluid transport.
• High Precision: Dimensional accuracy and roundness meet stringent requirements, making it suitable for applications requiring stringent precision.
Applications: Seamless steel pipe is commonly used in oil pipelines, reactor piping in chemical equipment, heating surface pipes in power plant boilers, and hydraulic cylinders in machinery manufacturing.

Seamless pipes are formed in one go through hot rolling, cold drawing and other processes, with no welds throughout the process! Compared with traditional welded pipes, it fundamentally avoids the problem of corrosion and leakage of welds, has higher strength and greater stability, and is simply the "durable king" in the pipeline industry~
✨ The weld-free design makes the overall pressure resistance and corrosion resistance of the pipe soar. Whether it is transporting hot water, gas, or high-temperature and high-pressure fluids in industry, it can operate stably for a long time, greatly reducing the risk of leakage and pipe bursts, and saving time and cost for repeated repairs!
Used in building structure support, bridge construction, Machinery Manufacturing: Manufacturing machinery parts and automotive components such as shock absorbers and fluid reservoirs.

Welded Pipe
Definition: Welded steel pipe, also known as welded pipe,It is a steel pipe made by welding steel plates or strips after curling and forming.
Features: Simple production process, high efficiency, a wide variety of specifications, and low equipment investment, but generally lower strength than seamless steel pipe.
Welded pipe is divided into straight seam welded pipe and spiral welded pipe. Straight seam welded pipe has a simple production process and low cost; spiral welded pipe has higher strength and can produce large diameter pipes from narrower billets. Welded pipe is divided into round welded pipe and special-shaped (square, rectangular, etc.) welded pipe. Used in building structure support, bridge construction, piling pipe, and scaffolding pipe. Machinery Manufacturing: Manufacturing machinery parts and automotive components such as shock absorbers and fluid reservoirs.
