Thermex TMT Bars (Thermo-Mechanically Treated Bars)

Thermex TMT Bars (Thermo-Mechanically Treated Bars)

Thermex TMT bars are high-strength reinforcement bars (rebars) that undergo a thermo-mechanical treatment process, enhancing their tensile strength, ductility, and earthquake resistance. They feature a tough outer layer for durability and a soft inner core for flexibility, making them ideal for reinforced concrete structures.

Uses:
– Reinforced Concrete Structures – Essential for buildings, ensuring strong foundations and structural integrity.
– Bridges & Flyovers – Used to enhance the durability and weight-bearing capacity of large infrastructure projects.
– Dams & Power Plants – Provides resilience against high-pressure environments and water force.
– Seismic Zone Construction – Ideal for earthquake-prone areas due to their superior flexibility and crack resistance.
