28 mm Deformed Rebar A3 for Export

28 mm Deformed Rebar A3 is a high‑strength reinforcing steel bar designed for structural applications that require strong load‑bearing performance. With its ribbed surface, reliable mechanical properties, and stable behavior under tensile forces, this product is widely used in large-scale construction and civil engineering projects.

Manufactured using high‑quality steel billets and controlled production processes, A3 grade rebar provides strong adhesion to concrete and ensures long‑term structural durability—making it suitable for international export markets.

Technical Specifications

• Diameter: 28 mm
• Type: Deformed (ribbed) reinforcing bar
• Grade: A3
• Standard Length: Typically 12 meters
• Surface: Ribbed pattern for improved bonding
• Application: Structural reinforcement in medium‑to‑heavy concrete elements

Mechanical Properties

A3 rebar is known for its high tensile strength and robust structural behavior.

• 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 allow the rebar to effectively resist tensile forces in reinforced concrete structures while maintaining sufficient ductility.

About A3 Rebar Grade

The A3 grade classification is a widely used standard in Iran’s rebar industry and is well‑recognized in regional export markets.

Key characteristics include:

• Higher strength compared to A1 and A2 grades
• Ribbed surface designed for excellent mechanical bonding with concrete
• Suitable for structural elements subjected to significant loads

Due to its high strength and relatively lower ductility, A3 rebar should not undergo excessive cold bending and is primarily used in structural reinforcement requiring rigidity and load‑bearing stability.

Advantages of 28 mm A3 Rebar

• High structural strength for medium and heavy construction
• Strong concrete bonding due to ribbed surface
• Increased load-bearing capacity
• Long-term stability for reinforced concrete structures
• Manufactured to meet export requirements

Applications

28 mm A3 Deformed Rebar is commonly used in:

• Structural beams and columns
• Reinforced concrete slabs
• Medium-to-large foundations
• Bridges and infrastructure projects
• Industrial construction
• Water and energy sector structures

This size is ideal for primary reinforcement in elements that require a balance of high strength and efficient weight distribution.
