14 mm Deformed Rebar A3

14 mm Deformed Rebar A3 is a widely used reinforcing steel bar designed for structural concrete applications that require reliable tensile strength and long‑term durability. With its ribbed surface, this rebar provides excellent bonding with concrete, improving load transfer and overall structural stability.

Produced from high‑quality steel billets through controlled hot‑rolling processes, A3‑grade rebars are known for their consistent mechanical properties and strength. The 14 mm size is especially popular in residential, commercial, and medium‑scale construction projects.

Technical Specifications

• Diameter: 14 mm
• Type: Deformed (ribbed) reinforcing bar
• Grade: A3
• Standard Length: Typically 12 meters
• Surface: Ribbed design for stronger bonding with concrete
• Application: Reinforcement in reinforced concrete elements

Mechanical Properties

A3 reinforcing bars provide strong tensile resistance and dependable 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 mechanical properties ensure adequate strength and ductility for reinforced concrete systems.

About A3 Rebar Grade

The A3 grade is one of the most common reinforcing steel types used in Iran and regional markets.

Key properties include:

• Higher mechanical strength than A1 and A2 grades
• Ribbed surface for superior concrete bonding
• Suitable for structural members under moderate to heavy loads

Due to its rigidity and relatively lower ductility, A3 rebar is generally not suitable for extensive cold bending.

Advantages of 14 mm A3 Rebar

• High tensile and structural strength
• Strong adhesion to concrete
• Suitable for medium‑load structural uses
• Ideal for beams, slabs, and general reinforcement
• Widely supplied for construction and export markets

Applications

14 mm A3 Deformed Rebar is commonly used in:

• Reinforced concrete beams and slabs
• Foundations and floors
• Residential and commercial construction
• Infrastructure and civil engineering projects
• Structural reinforcement frameworks

This diameter is frequently selected for general reinforcement in medium‑scale concrete elements.
