Knowledge Box - FAQs

  • What is QST bar?

    QST bars or Thermo-Mechanically Treated Bars are high-strength reinforcing bars having a soft core and a very strong external layer. While manufacturing QST bars they are first the steel wires are passed through a rolling mill stand. After that, these rolled steel bars are then passed through the Tempcore water cooling system which gives high strength to the bars.

  • How RS QST bars are manufactured?

    RS QST bars are manufactured using this specially designed Tempcore Technology. Under this process, the water pressure is optimized and this sudden change in the temperature makes the outer layer of the steel bar tough. Once the steel bar is cooled, it is further left for atmospheric cooling. This helps equalize the temperature difference between the outer layer and the soft inner core. Once the core of the QST bar cools down, it turns into a ferrite-pearlite mass. This design of tough outer layer and soft inner core makes the QST bars highly ductile.

  • Why you need QST bars?

    From homes and multi-storied buildings to flyovers and bridges, QST bars provide high strength to the structures. QST bars are able to withstand any amount of load. This improves the safety and longevity of the structure and secures it from any damages.

  • What are the available grades and product range of RS QST bars?

    • QST Bars from 8 mm- 20 mm diameter Grade available RB 500.
    • MS Round Bars from 8mm to 25mm
    • MS Angle Bars ¼” to 2”
    • MS Flat iron
    • GI Pipes ¼” to 6”
    • MS Coil 6mm

  • Why use RS QST bars?

    The following are the advantages of RS QST
    • High Strength
    • Higher elongation (which makes it safe for earthquake-prone areas)
    • High Bend/ re-bending properties
    • Corrosion resistant
    • High fatigue resistance
    • Good weldability

From The Desk of the Chairman
