The steel tmt bars receive a short, intensive cooling as they pass through the specially resigned Tempcore Water Cooling System after the last Rolling Mill Stand. The sudden quenching converts the surface layer of the steel bar to a hardened structure.
TMT Bars are backed by latest on Tempcore Technology, which makes it highly superior product in construction industry. To know more about WINGRIP Technology.
TMT Bars are available in Fe: 415 /500 /550/ 600 & Fe-415D, Fe500D, Fe 550D, Fe 600 grade which are much stronger than yesteryears' conventional Bars and give upto 20% stronger concrete structure with same quantity of steel.
