Thermex® Standards, The Benchmark

Thermex Licensees follow the Thermex Grades as given in the tables below.

Special importance is given to high ductility irrespective of the yield strength in keeping with the requirements of rebars for moderate, high and very high seismic hazard zones as found in the entire Indian Region.

Licensees are encouraged to only produce Grade Thermex 500 in line with global norms.
