TMT bars are the backbone of new constructions. With the help of new technologies, we offer your TMT (Thermo-Mechanically Treated ) bars that are tougher on the outside and soft on the inside. Construction of buildings, industrial sheds, transmission towers, dams, roads, and others require wire rods, structural products (Beams, Channels, Angles), and TMT bars. We provide our customers with the best quality TMT bars that are highly durable and malleable at the same time.
We use iron ore and Coal to produce 100% pure steel by integrating the German-based quenching system – THERMEX. Our products are certified for MS and CRS Grades through IS 2830:2012 compliance. Our TMT bars also comply with IS 1786:2008 for CRS, FE415, and Fe550D Grade.
