10 mm Deformed Rebar A3

10 mm Deformed Rebar A3 is a reinforcing steel bar designed for use in reinforced concrete structures where reliable tensile strength and strong bonding with concrete are required. The ribbed surface improves the mechanical connection between steel and concrete, helping distribute loads efficiently within structural elements.

Manufactured through controlled hot‑rolling processes from quality steel billets, A3 reinforcing bars provide consistent mechanical performance and durability. The 10 mm diameter is commonly used in stirrups, ties, reinforcement meshes, and light structural reinforcement in residential and commercial construction.

Technical Specifications

• Diameter: 10 mm
• Type: Deformed (ribbed) reinforcing bar
• Grade: A3
• Standard Length: Typically 12 meters
• Surface: Ribbed pattern for improved bonding with concrete
• Application: Reinforcement in reinforced concrete elements

Mechanical Properties

A3 reinforcing bars are designed to provide reliable tensile 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 properties support structural stability and long‑term durability in reinforced concrete systems.

About A3 Rebar Grade

The A3 grade is commonly used in construction projects in Iran and regional export markets due to its higher strength and reliable mechanical properties.

Key characteristics include:

• Higher strength compared to A1 and A2 rebar grades
• Ribbed surface that enhances bonding with concrete
• Suitable for structural components exposed to moderate loads

Because of its relatively lower ductility compared to softer grades, A3 rebar is generally not intended for heavy cold bending after production.

Advantages of 10 mm A3 Rebar

• Strong adhesion to concrete due to ribbed surface
• Reliable tensile strength for reinforcement applications
• Suitable for stirrups, ties, and reinforcement meshes
• Ideal for light to medium reinforcement structures
• Widely used in construction and export supply markets

Applications

10 mm A3 Deformed Rebar is commonly used in:

• Stirrups and ties in reinforced concrete beams and columns
• Reinforcement meshes and secondary reinforcement
• Slabs, walls, and light structural elements
• Residential and commercial building construction
• Civil engineering and infrastructure projects

This diameter is particularly suitable for secondary reinforcement and shear reinforcement elements.
