Description
-
Enhanced Strength and Durability:
The thermo-mechanical treatment process significantly increases the strength and durability of the bars compared to ordinary steel bars.
-
Improved Flexibility:
The soft inner core allows for bending and shaping, making them versatile for various construction applications.
-
Excellent Bonding with Concrete:
The ribbed surface of TMT bars provides a robust bond with concrete, enhancing the structural integrity of concrete structures.
-
Resistance to Corrosion:
The hardened outer layer offers better protection against corrosion compared to ordinary steel bars, extending the lifespan of concrete structures.
-
Superior Elastic Properties:
TMT bars exhibit higher residual stress and elasticity compared to other types of reinforcement bars like HYSD bars, according to Sugna TMT.
-
Widely Used in Various Structures:
TMT bars are used in a wide range of construction projects, including buildings, bridges, dams, and other infrastructure projects.
TMT bars are made by subjecting steel billets to a specialized process involving heating, rolling, and rapid cooling. This process creates a hardened outer layer and a soft inner core, resulting in the unique properties of TMT bars.
TMT bars are available in various grades, each with specific strength and ductility characteristics. Common grades include Fe-415, Fe-500, Fe-550, and Fe-600, with the number indicating the yield strength of the bar.
TMT bars are widely used in various construction applications, including:
- Reinforcement in concrete structures.
- High-rise buildings.
- Bridges and flyovers.
- Dams and other infrastructure projects.
- Industrial structures.
- Underground platforms in metro railway systems.
