12 mm Deformed Rebar A3

12 mm Deformed Rebar A3 is a high‑strength reinforcing steel bar commonly used in concrete structures that require reliable tensile performance, durable bonding with concrete, and long‑term structural stability. Its ribbed design enhances the grip within concrete, improving load transfer and minimizing slippage in reinforced concrete elements.

Manufactured through controlled hot‑rolling processes from quality steel billets, A3 rebar provides consistent mechanical properties and is widely used in residential, commercial, and infrastructure construction. The 12 mm diameter is particularly favored for stirrups, light to medium reinforcement, and dense reinforcement patterns.

Technical Specifications

• Diameter: 12 mm
• Type: Deformed (ribbed) reinforcing bar
• Grade: A3
• Standard Length: Typically 12 meters
• Surface: Ribbed pattern for strong bonding with concrete
• Application: Reinforcement in various reinforced concrete elements

Mechanical Properties

A3 reinforcing bars offer strong tensile performance and reliable structural characteristics:

• Yield Strength: approximately 400 MPa
• Tensile Strength: approximately 600 MPa
• Yield‑to‑Tensile Ratio: around 0.65 – 0.75
• Elongation: approximately 14%

These properties ensure effective load resistance and adequate ductility in reinforced concrete systems.

About A3 Rebar Grade

The A3 grade is widely used in Iran and regional construction markets for its high strength and structural reliability.

Key features include:

• Higher strength compared to A1 and A2 rebar grades
• Ribbed design for enhanced concrete bonding
• Suitable for structural elements subjected to moderate to heavy loads

Due to its rigid structure, A3 rebar is generally not suited for heavy cold bending after manufacturing.

Advantages of 12 mm A3 Rebar

• Excellent bonding with concrete due to ribbed profile
• High tensile strength for structural reliability
• Ideal for stirrups, ties, mesh, and secondary reinforcement
• Suitable for residential, commercial, and infrastructure projects
• Available for domestic use and international export supply

Applications

12 mm A3 Deformed Rebar is widely used in:

• Stirrups in reinforced concrete beams and columns
• Secondary reinforcement in slabs and foundations
• Dense reinforcement cages and shear reinforcement
• Walls, frames, and light to medium structural elements
• Residential, commercial, and civil engineering projects

Its versatile diameter makes it suitable for a wide range of structural reinforcement needs.
