TMT bars are the backbone of new constructions. With the help of new technologies, we offer your 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.
The unique rib design gives maximum Rib Area (AR) value, ensuring a strong, long-lasting Tiger Bond with cement (concrete).
The combined chemistry of steel and advanced quenching process makes S-E-L Tiger TMT Re-Bar fire and corrosion resistant.
S-E-L Tiger TMT Re-Bar's combination of high strength and superior ductility make it suitable for construction of residential, commercial and infrastructure projects.
Balanced proportion of Carbon and Manganese for better bendability to resist earthquakes.
S-E-L Tiger TMT Re-Bar can be easily welded into desired shapes without producing any defects leading to smoother surface conditions and lower thermal conductivity.
S-E-L Tiger TMT Re-Bar ensures the highest level of purity.
S-E-L Tiger TMT Re-Bar offers better bendability, re-bendability and ease of cutting.
The consistent quality of S-E-L Tiger TMT Re-Bar makes it apt for all construction needs.
