Birla TMT presents the Grade Fe 500D TMT Bar Birla Fe 500D TMT Bar - 16 mm, a thermomechanically treated IS 1786:2008 reinforcing bar with 16 mm nominal diameter in standard 12 m lengths. Certified to achieve 500 MPa yield, 565 MPa UTS, and 16% elongation, this bar is optimised for ductile frame construction and seismic-zone reinforced concrete structures where controlled ductility and strength are paramount. The QST-process dual microstructure — hardened rim plus tough core — provides the unique combination of high strength and energy-absorbing capacity essential for earthquake-resistant concrete structures.

• Certified Fe 500D grade conforming to IS 1786:2008 ductile reinforcement standard
• QST microstructure delivering 500 MPa yield with enhanced 16% elongation
• UTS 565 MPa meeting the higher tensile requirement of the D-suffix ductile grade
• Superior elongation ensures plastic hinge formation in seismic design scenarios
• Enhanced rib geometry for maximum concrete interlock and bond slip resistance
• Low impurity content supporting cold bendability and on-site fabrication
• Preferred by IS 13920 seismic detailing code for ductile frame structures
• Standard 12 m mill length for project scheduling, logistics, and on-site fixing
• Suitable for all seismic zone construction requiring ductile reinforcement
• Traceable quality records supporting structural design certification and audit
