Produced to IS 1786:2008 Grade Fe 415 by the thermomechanical treatment process, the Spark TMT Bar Spark Fe 415 TMT Bar - 16 mm offers 16 mm diameter bars in standard 12 m lengths with traceable mechanical performance. With guaranteed yield of 415 MPa, tensile of 485 MPa, and elongation of 14.5%, this bar is built for general construction, residential slabs, and low-rise structural concrete. 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.
