The Birla TMT TMT Bar Birla Fe 550 TMT Bar - 16 mm is a quench-and-self-temper treated reinforcing bar conforming to IS 1786:2008 Grade Fe 550, with 16 mm diameter and standard 12 m length. Achieving 550 MPa yield, 585 MPa tensile strength, and 10% elongation, it is ideally suited for heavy structural RCC, bridge decks, and high-rise construction. The thermomechanical treatment process creates a strong outer layer resistant to bending and cutting forces, while the ductile inner core absorbs energy under seismic and impact loads, ensuring structural resilience in reinforced concrete construction.
