Advantages of our Product


Better safety of structures: Because of higher Strength combined with higher Ductility.

Easy Working at site: Owing to better Ductility and Bend ability.

Resists Fire: Unlike Tor Steel/CTD Reinforcements bars, TMT bars have high thermal stability.

Resists Corrosion: the TMT process gives the bar superior strength and anti-corrosive properties. Controlled water-cooling prevents the formation of coarse carbides, which has been cited as the main cause for the corrosive nature of common bar. Another reason for better corrosion resistance is the absence of surface stresses caused by the cold twisting process.

Formability: Due to very high elongation values and consistent properties throughout the length of bar, TMT rebar have excellent workability and bend ability.

Earthquake resistance: The soft ferrite-pearlite core enables the bar to bear dynamic and seismic loading. TMT bars have high fatigue resistance to dynamic/ seismic loads due to its higher ductility quality. This makes them most suitable for use in earthquake prone areas.

Fine Welding Features: TMT rebar’s (having low carbon content) can be used for butt and other weld joints without reduction in strength at the weld joints.

Bonding Strength: External ribs running across the entire length of the TMT bar give superior bonding strength between the bar and the concrete. Fulfils bond requirements as per IS:456/78 and IS:1786/85.
