TMT Bars
To meet the changing trends of high rises due to space scarcity the builders require the strongest reinforce steel to meet the endurance level holding the masses of the tall structures. Reinforce concrete needs adequate bonding between steel and concrete to ensure the composite works efficiently. This perfect bonding is essential for those applications where structures are subject to unexpected forces to meet the requirements of the new engineered reinforcement structures and smart architectural concepts. The vital features of this high end steel TMT bar are as follows:
- Higher Strength
- Higher UTS/YS ratio(elongation)
- Higher fatigue strength
- Higher resistance to heat
- Higher resistance to corrosion
- Excellent weldability
- Excellent ductility
Best economical TMT bars having 20% more strength &20% more pocket friendly.
