Product Range
TMT Bars
Features:
- Low carbon content and made from fully killed steel.
- Higher yield strength & Ultimate tensile strength coupled with higher percentage elongation when compared to cold twisted bars of same grade.
- Easy bendability, weldability and excellent ductility ensures economy and safety of use.
- In-built ability to resist loss of strength at higher temperature.
- Require less energy for bending and re-bending along with superior reverse bending properties.
- Can be butt welded or lap-welded.
- Use of Fe-500 grade results in saving more than 15% in steel consumption when compared to cold twisted bars.
- Higher corrosion resistance and sesmic resistance compared to CTD.
- Ideally suited for any type-of concrete structure.
