TMT Rebars

TMT: Thermo Mechanically Treated or TMT bars are high-strength reinforcement bars having a hardened outer core and a soft inner core. They are manufactured under a process called Thermo Mechanical Treatment, after which they are named.They are manufactured by passing hot rolled steel billets through water, which hardens the surface and increases its tensile strength while the inner core stays at a comparatively warmer temperature and hence, the core becomes more ductile. This variation in the microstructure of the cross-section of the bar provides huge strength to the bar. Since there are no twisting or deformation processes employed in this method, TMT bars have no surface cracks or other defects as well
