  • Cost-effective.
  • High strength and hardness.


Round bars are long, cylindrical bars made from low carbon steel that have a smooth surface finish. They are commonly used in construction, manufacturing, and industrial applications due to their strength, versatility, and cost-effectiveness.

They may have different surface finishes, such as hot-rolled, cold-rolled, or polished, depending on the intended application. Additionally, mild steel round bars are relatively inexpensive compared to other types of steel, making them a popular choice for a wide range of applications.
