Fe 550D
TMT Bars
Fe denotes ferrous material i.e. iron from which the reinforcement steel bars (TMT Bars) are produced. Fe 550D stands for the base yield stress in N/mm2. Evaluation TMT Bars were presented as a one stage up mechanical miracle over standard Fe 415 evaluation item. The high corrosion resistance, excellent bend ability and great resistance on dynamic loading of Fe 550D are used in RCC constructions of building, bridges and other concrete structures.
