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 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.

TMT Bars/Rebars significantly increases the tensile strength of the structure. Rebar's surface is often "deformed" with ribs, lugs or indentations to promote a better bond with the concrete and reduce the risk of slippage.
