rebar A3

Description

Rebar A3 – High Strength Ribbed Reinforcing Steel Supplier from Iran

Rebar A3, also known as ribbed and twisted reinforcing steel, is the third grade of rebar used in modern concrete construction. It is characterized by its ribbed texture and fan-shaped twisted tread pattern that provides superior grip and structural strength. Designed with a yield strength of 400 MPa and a tensile strength of 600 MPa, A3 rebar delivers robust reinforcement ideal for beams, columns, and structural frameworks in both residential and industrial projects.

At Call2Supply, we supply and export A3 Rebar from Iran, sourcing directly from major domestic producers including Amir Kabir Khazar Steel, Khorasan Steel Complex, Esfahan Steel Company, Mianeh Steel, and Bafgh Yazd Steel. Our export division ensures international-grade quality, competitive pricing, and reliable delivery to clients worldwide.

Detailed Characteristics and Structural Benefits

The A3 Rebar grade is engineered to offer high performance under load-bearing stress. Its unique ribbed and twisted surface increases friction between the steel and the surrounding concrete, significantly improving the bonding capacity of reinforced elements.
The fan-shaped rib configuration, oriented along the longitudinal axis, enhances mechanical interlocking and provides better stress distribution within concrete structures. With a yield strength of 400 MPa and a tensile strength of 600 MPa, Rebar A3 outperforms A1 and A2 grades in both stiffness and structural endurance.

A3 Rebar contains higher carbon content, which increases strength and hardness but limits weldability — welding is not recommended for this grade. Instead, it is best used in mechanically connected or tied reinforcement systems. These properties make Rebar A3 particularly suited for load-bearing elements, including longitudinal reinforcement in beams, columns, and structural foundations.

Key Characteristics and Benefits

• Ribbed and Twisted Design: Fan-shaped ribs enhance concrete adhesion, ensuring superior stress transfer and bonding performance.

• High Strength Performance: With 400 MPa yield and 600 MPa tensile strength, A3 Rebar ensures stability under high structural stress.

• Enhanced Durability: Engineered to resist bending, cracking, and deformation in concrete under heavy loads.

• Precision Manufacturing: Produced under controlled metallurgical processes to maintain consistent quality and dimensional accuracy.

• Carbon-Enriched Alloy: Higher carbon content improves mechanical strength and hardness, providing robust performance for critical structural elements.

• Welding Restriction: Due to high carbon levels, welding is not permitted; mechanical joining is recommended for structural safety.

• Versatile Construction Use: Suitable for main reinforcement in beams, columns, bridges, and concrete frames.

Optimal Application Methods

Proper handling and installation ensure the best structural performance:

• Bending and Cutting: Mechanical tools are recommended for cutting and bending A3 rebars due to their hardness.

• Concrete Bonding: The ribbed and twisted pattern guarantees excellent bonding and minimizes slippage within the concrete.

• Joining Methods: Mechanical couplers or overlap ties should be used instead of welding to maintain structural strength.

• Storage and Handling: Keep rebars dry and protected from moisture to prevent rusting and maintain surface integrity before use.
