20 mm Deformed Rebar A3 for Export

20 mm Deformed Rebar A3 is a widely used reinforcing steel bar designed for structural concrete applications requiring reliable tensile strength and long‑term durability. With its ribbed profile and stable mechanical performance, this rebar ensures excellent adhesion to concrete and improves load transfer across structural elements.

Manufactured from high‑quality steel billets through controlled hot‑rolling processes, A3 rebar is a preferred choice in construction, infrastructure, and industrial projects across regional and international markets.

Technical Specifications

• Diameter: 20 mm
• Type: Deformed (ribbed) reinforcing bar
• Grade: A3
• Standard Length: Typically 12 meters
• Surface: Ribbed pattern for enhanced bonding with concrete
• Application: Structural reinforcement in concrete elements

Mechanical Properties

A3‑grade rebar provides reliable tensile resistance and stable structural performance.

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

These mechanical values help ensure sufficient strength and ductility for use in reinforced concrete systems.

About A3 Rebar Grade

A3 rebar is one of the most widely used reinforcement grades in Iran and local export markets.

Key features include:

• Higher strength compared to A1 and A2 grades
• Ribbed pattern for improved bonding with concrete
• Suitable for structural elements subjected to moderate to heavy loads

Because A3 rebar has higher strength and lower ductility than mild‑grade rebars, it is not recommended for extensive cold bending and is mostly used in direct reinforcement applications.

Advantages of 20 mm A3 Rebar

• Strong tensile and structural performance
• Excellent bonding with concrete due to ribbed profile
• Ideal for medium‑load structural applications
• Widely used in beams, slabs, and general reinforcement
• Produced according to export market requirements

Applications

20 mm A3 Deformed Rebar is commonly used in:

• Reinforced concrete beams and slabs
• Foundations and structural frameworks
• Mid‑scale construction and civil engineering projects
• Industrial and commercial buildings
• Infrastructure elements such as retaining structures and walkways

This diameter is especially popular for general‑purpose structural reinforcement in medium‑load applications.
