Carbon Steel Square Bar
Carbon Steel Square Bar is a solid bar stock product characterized by its square cross-section. It is manufactured by hot-rolling or cold-drawing various grades of carbon steel. Its properties and uses depend directly on the specific carbon content: Low Carbon (e.g., Q235): Offers high ductility, good weldability, and ease of machining. Used for general structural fabrication, railings, and decorative ironwork. Medium/High Carbon (e.g., 45#): Provides higher strength, hardness, and wear resistance. Used for axles, shafts, machinery components, and tools. Carbon Steel Square Bar is a versatile profile used across construction, machinery, and manufacturing industries where a flat-sided structure is needed.
