Nowadays TMT steels are commonly used in constructions. What is TMT? Why is it used than other types of steel? Well, before TMT was introduced Mild Steel (MS) bars, Cold Twisted Deformed (CTD) bars were primarily used with concrete for constructing buildings. Those steel were graded Fe 250 but their low strength was a problem for buildings requiring more strength. …

Thermo Mechanically Treated (TMT) process has been developed for providing quality reinforcement to structures. The TMT process is a revolutionary process as it provides the steel bars high tensile strength as well as ductility. There are different grades for TMT reinforced steels namely Fe 415, Fe 500, Fe 550, Fe 600, where the numbers denote the minimum yield strength. …
