Conforming to IS 1786:2008 Grade Fe 600, the Birla TMT TMT Bar Birla Fe 600 TMT Bar - 25 mm is a thermomechanically treated reinforcing bar in 25 mm diameter, supplied in standard 12 m lengths. The QST process imparts a hard tempered outer zone and a ductile core, achieving 600 MPa yield, 660 MPa UTS, and 10% elongation for reliable use in high-strength structural RCC, long-span bridges, and industrial concrete structures. The superior weldability, corrosion resistance, and bond characteristics of this TMT bar make it the preferred reinforcing steel for structural concrete across residential, commercial, and infrastructure applications.
