TMT bars or Thermo-Mechanically Treated bars are high-strength reinforcement bars having a tough outer core and a soft inner core.
To produce best TMT best quality iron ore is required.Most of the companies outs ource it,but we get it from our own mines so that quality is up to the mark.
Pig iron is the product of smelting iron ore (also ilmenite) with a high-carbon fuel and reductant such as coke, usually with limestone as a flux.
