Definition of carbon steel square tube

Carbon steel square tube is a square section tube formed by hot rolling or cold rolling process with low carbon steel (carbon content ≤0.25%) as raw material. Its core advantages are high strength, corrosion resistance and processability, which are widely used in construction, machinery manufacturing and other fields. As the source factory, we use RH vacuum refining technology to ensure the purity of steel and stable mechanical properties, to meet the requirements of British Standard (BS), American Standard (ASTM), European Standard (EN) and other international standards.
Carbon steel square tube production process
Refining of raw materialsRH vacuum refining process is adopted to accurately control the content of carbon, sulfur, phosphorus and other elements, which meets the requirements of different international standards on composition.Hot/cold rolling moldingThrough medium and thin slab continuous casting and rolling technology (such as X90 pipeline steel process), combined with cold rolling process to improve surface finish and dimensional accuracy, to ensure pipe strength and ductility.Laser cutting and moldingFiber laser cutting machine is used for high-precision cutting of other tubes, supporting diversified customization of round tubes, rectangular tubes and special-shaped tubes, with smooth incision and no burrs.Quality inspection and certificationMechanical property tests (such as tensile and impact tests) are carried out in strict accordance with American standard, British standard and European standard, and third-party certification (such as CE and ISO) is passed to ensure product export compliance.
The main use of carbon steel square tube
Construction projectIt is suitable for high-rise building frame and bridge support in Southeast Asia, and meets the structural safety requirements of British standard (BS 5950) and European standard (EN 10219).Manufacturing of machineryAs equipment skeleton or pipeline, adapted to the American standard (ASTM A500) strength and welding performance, to meet the needs of heavy machinery manufacturing.Automobile industryThe bumper frame, frame rail and beam, etc., using carbon steel square pipe can ensure the overall strength and safety of the car at the same time, reduce the weight of the body, improve the fuel economy and handling performance of the car.Infrastructure projectsUsed for pier pile foundation and pipe gallery construction (such as steel pipe pile pile technology), weather resistance and compressive resistance through Southeast Asia and other places of the standard verification.Agricultural facilitiesThe frame of the greenhouse uses carbon steel square tube, which can bear the weight of the film and the role of natural forces such as wind and snow, providing a stable growth environment for crops. The breeding fence is made of carbon steel square tube, which has good robustness and durability, and can effectively house livestock and poultry.Furniture manufacturingCarbon steel square pipe can be bent, welded and other processes, to produce a variety of unique shapes and styles, adding a sense of modernity and fashion to the furniture. At the same time, its surface can be electroplated, spraying and other treatment, improve the appearance and corrosion resistance.
