Round Steel

Round steel bars are solid long-strip steel products with a circular cross-section, belonging to commonly used basic industrial profiles. They are mainly made of Q235B, Q355B, 45# carbon steel and various alloy steels, produced by hot rolling, cold drawing, forging and other processes. They come in a wide range of diameters and specifications to meet different application requirements.
Round steel features uniform material composition and stable mechanical properties, with moderate strength and good toughness. It has excellent weldability, machinability, drillability, turning and heat treatment performance, making it easy for forming and secondary processing. It can be directly used as structural parts such as tie rods, columns, pins and embedded parts, and also as blanks for mechanical parts, fasteners and hardware tools.
Round steel bars are widely applied in construction engineering, machinery manufacturing, vehicles, ships, power equipment, mold processing, steel structure accessories, hardware products and other fields. With strong universality, high cost performance and convenient processing, they have become common basic steel products widely used in industrial production and engineering construction.
