TMT Bars
What are TMT Bars?
TMT bars are high-strength steel reinforcement bars shaped through thermo-mechanical treatment, a quenching process that creates a hard outer surface with a ductile inner core. Sri Durga TMT manufactures IS 1786-certified Fe 550 TMT bars in 8mm to 32mm sizes from our own continuously cast billets at our Chennai plant.
