Carbon Steel Square Bar
The Carbon Steel Square Bar is a robust, square-sectioned metal product manufactured from medium to high carbon steel, prized for its superior strength, rigidity, and versatility. Composed of iron with a carbon content of 0.25%–0.60% and trace elements such as manganese, silicon, sulfur, and phosphorus, this bar is engineered for structural, industrial, and decorative applications. Its uniform square cross-section ensures even load distribution and stability, making it ideal for machinery parts, shafts, frames, tooling, and construction supports. Compliant with ASTM A36, AISI 1018, and 1045 standards, it is available in hot-rolled, cold-drawn, or galvanized finishes. The bar offers excellent weldability and machinability, though uncoated surfaces may require anti-corrosion treatments. Its recyclability and cost-effectiveness make it a sustainable choice for heavy-duty and precision engineering projects.
