WHAT IS TMT BAR - THERMO-MECHANICAL TREATED BARS?
Thermo-Mechanically Treated Bars, (TMT Bars), are Extra High Strength Reinforcing bars which replacing any form of cold twisting, the technology of yesteryears. In this process, 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.
