TMT BARS

Thermo mechanically treated steel, known as TMT steel, can be described as a new-generation-high-strength steel having superior properties such as weldability, strength, ductility and bendability meeting highest quality standards at international level.

JR TMT RE-BARS is manufactured from superior quality billets manufactured in the same plant according to the requirement of the customers . At JR METAL our mantra is quality . JR TMT RE-BARS is available in FE-415 and FE-500 grades for sizes ranging between 8mm to 40mm . Special length orders for upto 22mtrs can be satisfied . The standard size of the brand is 40fts (12.2mtrs).

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
