Introduction to Carbon Steel Bars
Carbon Steel Bars are solid, long products produced from carbon steel alloys. Depending on the carbon content (low, medium, or high), these bars offer varying levels of strength, ductility, and hardness.
Carbon steel bars are widely used as structural components, shafts, support beams, machine parts, and reinforcement rods. Their excellent strength-to-cost ratio, weldability, and formability make them indispensable across heavy industries, infrastructure development, automotive manufacturing, and general fabrication work.
They are available in different cross-sections — round, square, flat, and hexagonal — and can be customized in size and finish to suit specific project requirements.
