Atibir Hi-Tech Pvt. Ltd. (Induction Furnace & Rolling Mill). Equipped with high speed Thermo Mechanical Treatment (TMT) coupled with Quenching and Tempering (Q & T) Process adopted in this plant produces SRIBIR TMT Bars, famous and highly demanded all over India. Our TMT bars are manufactured under stringent quality control policies and in various grades possessing all these qualities.
What is TMT ?
TMT is “Thermo Mechanically Treated Steel”
The name is derived from the metallurgical process called thermo-mechanical treatment that integrates work hardening and heat treatment into single process.
Advantage of this process is that bars do not need cold twisting and hence these bars show excellent resistance to corrosion.
APPLICATIONS :- General purpose concrete re-enforcement structures, Bridges, Flyovers, Dams, Buildings, Industrial structures, Concrete roads, etc.
