FEATURES:
Resists fire: Withstands temperatures up to 500 degrees Celsius.
Resists corrosion: The TMT process gives the bar superior strength and good
anti-corrosive properties.
Earthquake resistance: The soft ferrite-pearlite core enables the bar to bear
dynamic and seismic loading.
Malleability: TMT bars are most preferred because of its flexible nature
Enables welding: They have fine welding features.
Bonding strength: External ribs running across the entire length of TMT bar
give superior bonding strength between the bar and the concrete.
Cost-effective: A high tensile strength and better elongation value gives you
great savings
