Produced to IS 1786:2008 Grade Fe 500D by the thermomechanical treatment process, the Birla TMT TMT Bar Birla Fe 500D TMT Bar - 12 mm offers 12 mm diameter bars in standard 12 m lengths with traceable mechanical performance. With guaranteed yield of 500 MPa, tensile of 565 MPa, and elongation of 16%, this bar is built for ductile frame construction and seismic-zone reinforced concrete structures. The superior surface ribbing pattern of this TMT bar promotes strong concrete-to-steel adhesion, while its low carbon equivalent ensures easy site welding without compromising structural strength.
