16 mm Deformed Rebar A3

16 mm Deformed Rebar A3 is a high‑strength reinforcing steel bar commonly used in reinforced concrete structures that require reliable tensile strength and long‑term durability. Its ribbed surface improves bonding with concrete, helping distribute loads effectively and enhance the stability of structural elements.

Manufactured from quality steel billets through controlled hot‑rolling processes, A3 reinforcing bars provide consistent mechanical performance and durability. Due to its balanced strength and workability, 16 mm rebar is widely used in residential, commercial, and infrastructure construction projects as well as international steel markets.

Technical Specifications

• Diameter: 16 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 structures

Mechanical Properties

A3 reinforcing bars are designed to provide strong tensile resistance and 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 mechanical properties ensure structural stability and long‑term durability in reinforced concrete systems.

About A3 Rebar Grade

The A3 grade is one of the most commonly used reinforcing steel grades in Iran and regional export markets.

Important characteristics include:

• Higher strength compared to A1 and A2 rebar grades
• Ribbed surface design that increases bonding strength with concrete
• Suitable for structural components subjected to moderate to heavy loads

Because of its higher strength and lower ductility compared with softer grades, A3 rebar is generally not recommended for extensive cold bending after production.

Advantages of 16 mm A3 Rebar

• High tensile strength and structural reliability
• Strong adhesion to concrete due to ribbed design
• Suitable for medium structural loads
• Widely used in reinforced concrete frameworks
• Manufactured for construction and international supply markets

Applications

16 mm A3 Deformed Rebar is commonly used in:

• Reinforced concrete beams and columns
• Concrete slabs and foundations
• Residential and commercial buildings
• Infrastructure and civil engineering projects
• Structural reinforcement frameworks

This diameter is frequently used in main reinforcement for medium structural elements.
