TMT Rebars are integral to every construction project. During construction, the TMT rebars and concrete complement each other to mold the Reinforced Cement Concrete (RCC) structure into any desired shape, with the rebars providing the requisite tensile strength to withstand the load.

Simhadri TMT Rebars are manufactured using our integrated manufacturing process starting from ironmaking. High grade iron ore and pellets are processed into high quality sponge iron in our facilities which is then converted into crude steel in our steel melting shop and made into billets.

The billets are then thermo-mechanically treated into rebars having superior properties using state-of-the art TEMPCORE Process from the CRM Group (Cente de Recherches Métallurgiques) of Belgium. TEMPCORE technology produces rebars with higher strength, ductility, bendability & weldability surpassing the requirements of Fe500D, Fe550D & Fe500DCRS rebars standards.

Our high quality physical and mechanical specifications help to significantly increase the tensile strength of the structure. Our hot rolled round rebars with deformation at the surface promote a strong bond with the concrete.
