German Thermex Technology

How THANE TMX Gains Its Strength

THANE TMX thermo mechanically treated bars are manufactured through the proven German water-quenching process. Each stage develops the strength, ductility and dependable performance required for modern construction.

Billet acquisition for THANE TMX steel bars
01

Billet Acquisition

The manufacturing process of Regency Thermex TMT Bars starts with the acquisition of high-quality raw materials in the form of billets.

Re-Heating Furnace

Once the billets pass quality checks, they are transferred to a Re-Heating Furnace, where they are heated to a temperature of 1100°C to 1150°C.

Rolling Mill Stand

After reaching the desired temperature, the billets are rolled through multiple mill stands to achieve the required diameter & length.

Thermex Quenching

The rolled bars then enter the Thermex quenching system, a German technology that forms tempered martensite, boosting strength, toughness, and ductility.

Cooling Bed

The quenched bars are then naturally cooled on cooling bed, allowing the core to form a ferrite-pearlite structure, which improves tensile strength, ductility, and weldability.

Quality testing of THANE TMX steel bars
07

Quality Testing

Samples are drawn during production which undergo stringent physical and chemical tests, including chemical analysis, tensile tests, and bend/rebend tests, to ensure top-tier quality.

Dispatch of THANE TMX steel bars

Dispatch

Once approved, the bars are marked & tagged. They are then dispatched after weighted to confirm the correct quantity is being dispatched to construction sites along with a quality test certificate.

Built for Demanding Construction

Advantages of the THANE TMX Process

  • Controlled water quenching develops a strong, hard outer surface on every bar.
  • Self-tempering retains a ductile core for improved bendability and structural reliability.
  • Atmospheric cooling creates a balanced ferrite-pearlite core for dependable performance.
  • The Thermex process delivers a consistent combination of high strength and ductility.
  • Process-controlled rolling and cooling support uniform quality across THANE TMX bars.
