Carbon Steel Rebar

Carbon steel rebar is a long steel product characterized by its ribbed surface and high tensile strength. It is typically manufactured from low to medium carbon steel grades, with a series of deformations or ribs along its length to provide mechanical anchorage in concrete. Carbon steel rebar is produced through hot rolling or cold rolling processes, followed by quenching and tempering for improved mechanical properties.

Typical Chemistry:

The chemical composition of carbon steel rebar can vary based on the grade and specific requirements of the application. However, typical compositions include:

  • Carbon (C): 0.20% to 0.60%
  • Manganese (Mn): 0.60% to 1.20%
  • Phosphorus (P): ≤ 0.05%
  • Sulfur (S): ≤ 0.05%
  • Silicon (Si): ≤ 0.30%
  • Other Alloying Elements: Trace amounts of other elements may be present to enhance specific properties, such as corrosion resistance or weldability.

Physical Properties:

Carbon steel rebar exhibits the following typical physical properties:

  • Tensile Strength: 400 MPa to 600 MPa
  • Yield Strength: 250 MPa to 500 MPa
  • Elongation: 8% to 18%
  • Rib Configuration: Deformed ribs along the surface to enhance bonding with concrete.
  • Diameter Range: Typically ranges from 6 mm to 40 mm, with larger diameters available for special applications.
  • Weight: Varies depending on diameter and length, typically measured in kilograms per meter (kg/m).
  • Density: Approximately 7.85 g/cm³


Key features of carbon steel rebar include:

  • High Strength: Provides superior tensile strength and ductility, enhancing the structural integrity of concrete structures.
  • Excellent Bonding: Deformed ribs along the surface improve mechanical anchorage and bonding with concrete, reducing slippage and enhancing load transfer.
  • Corrosion Resistance: Depending on the coating or surface treatment, carbon steel rebar can offer good resistance to corrosion in various environments.
  • Durable: Resistant to wear, fatigue, and environmental degradation, ensuring long-term performance in demanding applications.
  • Versatility: Suitable for a wide range of construction and infrastructure projects, offering flexibility in design and application.
  • Cost-Effective: Relatively low cost compared to alternative reinforcement materials, providing economical solutions for construction projects.
  • Availability: Widely available in various diameters, lengths, and grades to meet project specifications and requirements.
