Tmt Bar By Dina Iron & Steel Ltd.

We are ranked amongst the foremost firms that are engaged in manufacturing and supplying of TMT Bar in Patna, Bihar, India. These are manufactured in different dimensions ranging from 8mm to 25mm. We use in house manufactured MS Billets in our rolling mill rather then inferior alternative ingots which have impurities in them which somewhat effects the durability and other properties of the manufactured steel.
We use latest thermo mechanical treatment rather then the traditional cold twisting.

Thermo Mechanical Treatment is latest technology for manufacturing bars, it gives bars the combination of properties that will help to last decades.
Billets are reheated into oil or coal fired reheating furnace.
These reheated mild steel billets are passed through successive pair of grooved rollers i? 3 roughing, 4 intermediate, 2 finishing, 4 continuousi? respectively.
When the red hot bar leaves the last rolling stand it has to go through the treatment process.
