Welspun power & Steel limited (WPSL), a part of the US $ 3000 million Welspun Group, has set up a state-of-the-art facility to manufactured Ribbed thermo mechanically treated (TMT) rebars. The heat treatment process ensure that the rebars meet stringent quality standards and exhibit higher strength, better ductility, bend ability and weldability over the conventional bars used in the construction industry.

The process utilizes residual heat from the rolling process to attain the desired mechanical properties. Ingots / billets, which are heated in the re-heating furnace, are rolled through a series of rolling stands and progressively reduced to the final desired size and shape. As the hot rolled rebar emerges from the finishing stand of the bar mill, it is rapidly cooled. This quenching process by a special water spray system convert the surface layer of the bar to a hardened “Martensitic 'structure,  while the core remains “Austenitic'

In the past, the conventional mild steel round having low yield strength were used for concrete reinforcement. These bars were then replaced by cold Twisted Deformed Bars exhibiting better yield strength.

Even with controlled carbon content, these bars continued to have the inherent problem of poor weld ability and ductility. Beside, additional twisting operation induced torsional stresses, which further reduced the corrosion resistance.

 

The heat treatment process in Welspun TMT Rebar's eliminates all these undesirable effects. thus higher strength is attained even with lower carbon content and they also have excellent ductility, outstanding bend ability and superior weld ability.

 

The low temperature rolling further enhance the quality of welspun TMT Rebars by way of higher strength .

 

Besides this because of tension free rolling close tolerance is possible and uniform quality of the product of the product is guaranteed.

 

Further more Welspun TMT Rebars facilities ensure easy and safe handling and eliminates any damage to the product.
