The basic QST process and subsequent improvements are patented worldwide. Due to its simplicity and ease-of-operation, THERMEX QST Technology gained immediate global acceptance. Rolling mills are authorized to use Thermex Technology, only on a License basis. It is mandatory for all Thermex licensees, to obtain all critical and proprietary equipment for the Thermex QST System, from H&K India. This reduces the start-up time without compromising on the quality. The desired Thermex rebar properties are also established right from the day “one”.
TMT is not a brand, but the generic name given to rebars produced using a general rolling and quenching process. Many rolling mills do not have a proper quenching & self-tempering system. Hence the rebars produced through such systems don’t necessarily comply with BIS and International standards.
