25 mm Deformed Rebar A3 for Export

25 mm Deformed Rebar A3 is a high‑strength reinforcing steel bar commonly used in reinforced concrete structures that require strong load‑bearing capacity and structural stability. With its ribbed surface and reliable mechanical properties, this type of rebar ensures excellent bonding with concrete and improved structural integrity.

Produced from high‑quality steel billets using controlled rolling processes, A3 rebar is widely used in construction, infrastructure, and industrial projects. Its strength and durability make it a suitable choice for international export markets where reliable reinforcement materials are required.

Technical Specifications

• Diameter: 25 mm
• Type: Deformed (ribbed) reinforcing bar
• Grade: A3
• Standard Length: Typically 12 meters
• Surface: Ribbed pattern to improve bonding with concrete
• Application: Structural reinforcement in reinforced concrete elements

Mechanical Properties

A3 reinforcing bars provide strong resistance to tensile forces and reliable performance in structural applications.

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

These mechanical characteristics allow the rebar to maintain structural strength while providing sufficient ductility for reinforced concrete systems.

About A3 Rebar Grade

The A3 grade is widely used in Iranian steel standards and is commonly traded in regional and international export markets.

Important characteristics of A3 rebar include:

• Higher strength compared to A1 and A2 rebar grades
• Ribbed surface design for strong adhesion to concrete
• Suitable for structural elements subjected to significant loads

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

Advantages of 25 mm A3 Rebar

• High load‑bearing capacity for structural reinforcement
• Strong mechanical bonding with concrete
• Suitable for medium‑to‑heavy construction projects
• Reliable performance in structural frameworks
• Produced for international export markets

Applications

25 mm A3 Deformed Rebar is widely used in:

• Reinforced concrete beams and columns
• Large foundations and structural frameworks
• Bridges and infrastructure projects
• Industrial and commercial buildings
• Heavy construction and civil engineering projects

This diameter is commonly used in primary reinforcement of structural elements where high strength and durability are essential.
