TMT Bars
High Strength for Critical Applications
The Re-bars Fe 550D is a special grade of TMT Re-bars produced under specific process conditions resulting in increased strength as compared to Fe 415/415D grade TMT Re-bars. Fe 550D Re-bars are ideal for applications in heavy load structures like airport, dams, flyover, national highway, bridges and other critical structures where high yield load is required without compromising on the ductility. In addition to the features of MS TMT Re-bars exhibit the following characteristics
Special Weld ability
MS TMT Re-bars do not require pre or post welding treatment as they have low carbon content and are produced under controlled thermo mechanical treatment.
