18 mm Deformed Rebar A3 for Export

18 mm Deformed Rebar A3 is a high‑strength reinforcing steel bar widely used in reinforced concrete construction. Its ribbed surface improves bonding with concrete, allowing better load distribution and structural stability in various building and infrastructure projects.

Manufactured from quality steel billets through controlled hot‑rolling processes, A3 reinforcing bars provide reliable mechanical performance and durability. These characteristics make them suitable for structural reinforcement in both domestic construction and international export markets.

Technical Specifications

• Diameter: 18 mm
• Type: Deformed (ribbed) reinforcing bar
• Grade: A3
• Standard Length: Typically 12 meters
• Surface: Ribbed pattern for improved adhesion to concrete
• Application: Reinforcement in reinforced concrete structures

Mechanical Properties

A3 grade rebars are designed to provide strong resistance to tensile forces while maintaining reliable 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 properties help ensure durability and structural integrity in reinforced concrete systems.

About A3 Rebar Grade

The A3 rebar grade is commonly used 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 strong bonding with concrete
• Suitable for structural components subjected to moderate to heavy loads

Because A3 rebar has relatively high strength and lower ductility than softer grades, extensive cold bending after production is generally not recommended.

Advantages of 18 mm A3 Rebar

• High structural strength and durability
• Strong adhesion with concrete
• Suitable for medium‑load structural applications
• Reliable reinforcement performance in construction projects
• Produced for international export markets

Applications

18 mm A3 Deformed Rebar is commonly used in:

• Reinforced concrete beams and columns
• Structural foundations and slabs
• Residential and commercial construction
• Infrastructure and civil engineering projects
• General reinforcement in concrete frameworks

This diameter is frequently used in main reinforcement of medium‑scale structural elements.
