•  Controlled low temperature rolling is practiced to give higher      strength to the structures.

  •   Chemical composition is maintained strictly as per standards       by our plant manufacturing raw materials.

  •   Facility to roll special sizes and length as per specific       requirement.
 
  All Balbir Thermex Bars ,
  rolled from fully killed steel ,
  conform to standards as mentioned below
