◎ TMT rebars (Thermo-Mechanically Treated Reinforcement bars), is one of the very commonly used construction materials. ◎ These provide the needed sturdiness for the building structures and ensure their longevity. ◎The thermo-mechanical treatment helps in toughening the crust of the outer steel and leaving the inner core incredibly soft to provide strength along with ductility and bendability. ◎ These are manufactured through 2 different routes of manufacturing which define the category of TMT bars, namely Primary and Secondary TMT.
