A2 rebar is one of the most widely used reinforcement steel grades in the construction industry, manufactured according to the ISIRI 3132 standard. This grade is known for its moderate strength, good ductility, and excellent bendability, making it ideal for use in elements that require shaping or forming.
A2 rebars are produced with a spiral (helical) rib pattern, offering better flexibility compared to the A3 grade. For this reason, A2 is commonly used in stirrups, ties, hoops, beams, slabs, and reinforced concrete frameworks where bending and shaping are essential.
This grade is mainly available in 8 mm, 10 mm, and 12 mm diameters, which are among the most frequently used sizes for light to medium reinforcement applications.
Mechanical Properties of A2 Rebar
- Yield Strength (Re): approx. 340 MPa
- Ultimate Tensile Strength (Rm): approx. 500 MPa
- Ductility: High bendability (suitable for stirrups)
- Rib Pattern: Spiral ribs (helical)
Thanks to the balance between strength and flexibility, A2 rebar is considered one of the most practical and economical options for general construction needs.
