Word of Caution

TMT process is a highly sensitive process. Many small re-rollers merely pass the bars through normal water without specific treatment required to produce High Strength Bars. User needs to be warned that yield strength of such bars in most instance is below FE 415 Grade which is not suitable for construction at all.

We are using Thermex® Technology for producing TMT Thermex® Bars. Hence, specify RAMSARUP™ TMT BY NAME.
