PULKIT- TMT Thermo-Mechanically-Treated Re-Bars

What is a TMT ?


It is the popular acronym for thermo-mechanical-treatment.

What is the Thermo Mechanical Treatement Process ?

This is a special heat-treatment process,wherein the heat treatment is from the rolling process itself.

At the exit of the rolled product,the ribbed bar is subjected to the TMT process,which involves 3 stages.

Stage 1: Successive steps of rapid quenching in a special water system converting the surface layer of ribbed bar into hardened structure.

Stage 2: The tempering process involving the flow of heat from the core of the bar to the surface

Stage 3: Finally, the cooling the bars in atmospheric air on the cooling bed. This transforms the outer case of the bar into tempered martensitic state, while internally the bar will be a fine ferrite pearlite core. The TMT process eliminates all undesirable qualities of the normally treated bar.

The Pulkit TMT re-bar, therefore, attains higher strength and achieves excellent ductility,enhanced bendability and superior weldability.



APPLICATIONS

Pulkit- TMT re-bars find wid applications in different spheres including coastal and marine environments which are susceptible to corrosion.

General purpose concrete reinforcement structures,Bridges,Flyovers,Dams,Thermal and Hydel Power plants,Industrial structures,High-rise buildings, Underground platforms in Metro Railways and Rapid Transport Systems.
