Produced to IS 1786:2008 Grade Fe 550 by the thermomechanical treatment process, the Birla TMT TMT Bar Birla Fe 550 TMT Bar - 20 mm offers 20 mm diameter bars in standard 12 m lengths with traceable mechanical performance. With guaranteed yield of 550 MPa, tensile of 585 MPa, and elongation of 10%, this bar is built for heavy structural RCC, bridge decks, and high-rise construction. 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.

• IS 1786:2008 Fe 550 grade with traceable strength and elongation test records
