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.
CHEMICAL PROPERTIES :
Grade C%Max* S%Max P%Max
Mn%Min Si%Max
Fe-415 0.30 .055 .055 .55 .35
The most commonly used steel
bar for concrete
reinforcement is
TOR steel. The other names of
TOR steel are CTD bar,
deformed
steel bar, twisted steel bar, HSD
bar, CWD bar etc. These TOR
steel
bars can be used for general
concrete reinforcement in
buildings, roads, bridges etc.
These steel bars process a
combination of strength and
ductility that is far in excess of
minimum limits specified in
standard IS:1786.
