Tor steel which is also known as cold twisted bar.These are
steel bars with surface deformations formed by twisting the
steel after elongation. it has less yeild strength.


Thermo Mechanically Treated (TMT) bars have revolutionised
the industry with its superior quality as against the cold
twisting process to manufacture the traditional
reinforcement bars. The special heat treatment process
ensures greater strength, excellent ductility, enhanced
bendability and much superior weldability.
