Hariom Steels is one of the top leading suppliers in steel industry in India providing grand quality TMT bars. Our TMT bars are the superior quality reinforcement bars with the unique & innovative rib patterns which ensure high strength, weld ability, ductility, and bend ability thus matching the International quality standards. They are widely used in constructing buildings, bridges, flyovers, dams, industrial structures, high-rise buildings and underground platforms etc.

This superior quality TMT steel bars are produced using Hot rolling process where heated Iron billets continuously pass through the rollers of decreasing diameter. Once they come out of the last rolling mill the steel bars are passed through water cooling system for thermo mechanical treatment. The technology is referred as TEMPCORE technology which gives out hard yet ductile bar thatis the cooling system makes the outer surface of the bar cooler and harder but with a warm and soft inner core.
