The Spark Fe 415 TMT Bar Spark Fe 415 TMT Bar - 7 mm is produced through the thermomechanical treatment process to comply with IS 1786:2008, delivering a 7 mm diameter bar in standard 12 m lengths with certified mechanical properties. With a guaranteed yield strength of 415 MPa and tensile strength of 485 MPa, this TMT bar is purpose-engineered for general construction, residential slabs, and low-rise structural concrete. Its ribbed surface profile provides excellent mechanical bond with concrete, while the controlled ductility of 14.5% elongation ensures structural safety under seismic and dynamic loading conditions.
