Carbon Steel Square Bars are strong and adaptable square-cross-sectioned solid steel sections that are frequently utilised in general engineering, fabrication, and structural support. These bars, which meet international standards like ASTM, AISI, and BS, are produced in a variety of grades, including EN8, C45, A36, and 1018. They can be purchased hot-rolled or cold-drawn. Carbon steel square bars are utilised in a variety of industries, including construction, automotive, agriculture, and machinery manufacturing, due to their strength, machinability, and durability. They are perfect for applications needing both structural integrity and dimensional accuracy because of their consistent shape and high load-bearing capacity.
Depending on the grade, carbon steel square bars are made with different amounts of carbon (usually between 0.15% and 0.60%) as well as silicon, sulphur, phosphorus, and manganese. For better hardness and wear resistance, C45 grade, for instance, contains more carbon. Tensile strength ranges from 400 to 700 MPa, yield strength ranges from 250 to 450 MPa, and elongation ranges from 15 to 22%. These bars can be heat-treated (quenched and tempered) for increased toughness and have good weldability and machinability. Variants that are cold-drawn have superior surface finish and dimensional tolerance, which makes them appropriate for precision applications.

Square bars of carbon steel are frequently used in applications that call for strength, stiffness, and ease of fabrication. Construction frameworks, automotive components, support brackets, tool and die manufacturing, agricultural equipment, and general fabrication are examples of common applications. They are frequently utilised for machined components in mechanical assemblies, spacers, keys, and shafts. For custom manufacturing, they are simple to cut, weld, and drill due to their consistent geometry. They are utilised in fencing systems, railings, gates, and gratings in the construction sector. They are a common raw material in fabrication shops and heavy industries due to their affordability and adaptability.
