Deformed Rebar

Deformed rebar is a ribbed steel reinforcement bar designed for superior concrete bonding in construction projects. Available in grades A2 (240MPa), A3 (400MPa), and A4 (500MPa), it provides exceptional tensile strength (500-700MPa) for structural integrity in demanding environments.

Meta Description:Deformed rebar (A2-A4 grades) for concrete reinforcement. 400-500MPa yield strength, ribbed design for optimal bonding. ASTM/BS/DIN certified.
Categories

Deformed rebar plays an essential role in the construction industry, mainly serving to reinforce concrete structures. Characterized by raised ribs along its surface, it establishes a strong bond with concrete, thereby improving structural integrity and resistance to stresses and external forces. These rebars come in different grades, including A2, A3, and A4, each tailored for specific uses and offering distinct properties. Widely utilized in civil engineering and construction, deformed rebar is a key material for building bridges, roads, concrete reservoirs, and reinforced concrete frameworks. Its superior strength, combined with resistance to environmental factors like humidity and corrosion, makes it a durable and economical choice for long-term projects. Furthermore, its weldability (with some limitations in grade A4) and high tensile strength enhance its versatility, making it well-suited for various structural applications.

Application & Industries

Deformed rebar is widely used in the construction and civil engineering sectors due to its superior strength and bonding ability with concrete. It is particularly utilized in:

  • Reinforced concrete structures
  • Bridges and highways
  • Buildings and skyscrapers
  • Dams and tunnels
  • Coastal and high-humidity environment projects
