Latham Steel, a reliable manufacturer and supplier based in Hamilton, New Zealand, specializes in high-quality Carbon Steel Square Bars that cater to a variety of structural, engineering, and fabrication needs. These bars are celebrated for their impressive strength, good machinability, and exceptional weldability, making them perfect for both heavy-duty and precision manufacturing tasks. Latham Steel guarantees precise dimensional tolerances, smooth edges, and consistent material quality across all sizes. Carbon Steel Square Bars find their place in construction, machinery, automotive components, frameworks, and general fabrication, providing a durable and cost-effective solution for projects that demand strong, versatile, and easily workable steel sections.
Carbon Steel Square Bars are generally made from low- to medium-carbon steel grades like AISI 1018, 1020, 1045, or similar. Their composition features controlled amounts of carbon, manganese, silicon, sulfur, and phosphorus. The mechanical properties differ by grade:
Low-carbon grades are known for their excellent weldability and formability.
Medium-carbon grades offer increased strength, hardness, and wear resistance.
These square bars exhibit good tensile and yield strength, stable hardness, and strong machinability for cutting, drilling, milling, and shaping. Their balanced chemistry ensures reliable performance in both structural and mechanical applications.
