32 mm Deformed Rebar A3 for Export

32 mm Deformed Rebar A3 is a heavy‑duty reinforcing steel bar designed for structural reinforcement in large construction and infrastructure projects. Due to its high diameter and mechanical strength, this rebar is widely used in load‑bearing concrete elements such as foundations, columns, and bridges.

Manufactured using high‑quality steel billets and controlled rolling processes, A3 grade rebar provides strong bonding with concrete and excellent resistance to tensile stress. Its ribbed surface improves mechanical interlock with concrete, helping structures withstand heavy loads and long‑term stress.

Technical Specifications

• Diameter: 32 mm
• Type: Deformed (ribbed) reinforcing bar
• Grade: A3
• Standard Length: Typically 12 meters
• Surface: Ribbed pattern for improved bonding with concrete
• Application: Structural reinforcement in heavy concrete structures

Mechanical Properties

A3 grade reinforcing bars are known for their high tensile capacity and structural performance.

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

These mechanical properties allow the rebar to resist significant tensile forces while maintaining sufficient ductility for structural applications.

About A3 Rebar Grade

The A3 rebar grade is a commonly used classification in Iranian reinforcing steel standards and is widely traded in regional export markets.

Key characteristics include:

• Higher strength compared with A1 and A2 rebar grades
• Ribbed surface design for stronger mechanical bonding with concrete
• Suitable for load‑bearing structural components

Because of its relatively high strength and lower ductility compared with softer grades, A3 rebar is generally not recommended for heavy cold bending after production. It is mainly used in structural reinforcement where high strength and stability are required.

Advantages of 32 mm A3 Rebar

• Very high structural load capacity
• Excellent bonding with reinforced concrete
• Suitable for heavy civil engineering projects
• Reliable performance in large structural elements
• Manufactured for export markets and large construction projects

Applications

Due to its large diameter and strength, 32 mm A3 rebar is commonly used in:

• Large concrete foundations
• Structural columns and beams
• Bridges and infrastructure projects
• Industrial construction
• Dams and heavy civil engineering structures

This size of rebar is typically used in primary reinforcement of high‑load structural elements.
