THERMEX

THERMEX is the patented technology to manufacture thermo processed bars worldwide. THERMEX bars have 60% market share worldwide. The Thermex Cooling Technology involves subjecting the bar to predetermined quantity of high-pressure water after the last rolling mill stand. This treatment converts the bar surface to a hardened structure. The subsequent phase involves cooling at ambient temperature to allow the hot core to temper the surface through thermal exchange. This results in a unique structure of tempered martensite in the peripheral zone and a fine grain ferrite-pearlite at the central zone. Such a structure is the guarantee of a THERMEX  Bar.

THERMEX, 500 & 550 BARS supplied by STC will carry ISI mark and conform to IS 1786 – Fe 415, Fe 500 & Fe 550 grades to ensure minimum Tensile Strength of 500 and 550 N/mm2 (minimum) respectively.

Steeltradeco team honorably gather the best bar that manufactured by THERMEX tech and presents it to its customer. These ribbed bars are called as AJ520 or A4. In British standards, they called as B500C  and in American standards(ASTM) it is famous as a grade75.

However by using A4 rebars we can reduce our building weight up to 30% and also use lesser rebars in constructional acts.

Thanks to Thermex technology, A4 rebar’s bending is same as the other bars.

At end we name some advantage of the bars that produced by THERMEX tech so you can easily compare it with normal rebars.

  • HIGHER STRENGTH
  • BETTER ELONGATION
  • EXCELLENT WELDABILITY
  • EARTHQUAKE RESISTANCE
  • CORROSION RESISTANCE
  • HEAT RESISTANCE
  • SUPER DUCTILITY
  • EASY WORKABILITY

STC’s  A4 rebar that manufactured by high quality billet with THERMEX tech makes your building lighter and Stronger.
