Technical Description & Overview

Sarvottam Steel supplies primary-route manufactured Thermo Mechanically Treated (TMT) rebars engineered for high tensile strength, superior ductility, and exceptional bendability. Manufactured using advanced Quenching & Self-Tempering (QST) technology, our TMT bars feature a tough outer martensitic layer with an inner soft ferrite-pearlite core, ensuring critical resistance to seismic shocks, elevated temperatures, and corrosive environments.
