Spark Fe 415 TMT Bar Spark Fe 415 TMT Bar - 36 mm is a high-strength thermomechanically treated reinforcing steel bar produced to IS 1786:2008, featuring a 36 mm nominal diameter in standard 12 m mill lengths. Delivering a minimum yield of 415 MPa, tensile strength of 485 MPa, and elongation of 14.5%, this bar is designed for general construction, residential slabs, and low-rise structural concrete where reliable load transfer and ductility are critical. The distinct transverse and longitudinal rib pattern ensures maximum mechanical interlock with concrete, reducing slip and enhancing structural integrity in reinforced concrete members.
