Balaji Shakti Thermex TMT bars in Fe 415 grade are thermo-mechanically treated reinforcement bars designed to deliver high strength with reliable ductility for RCC structures. The 40 mm diameter bar offers a good balance between load-carrying capacity and steel consumption, making it suitable for a wide range of structural members.

These bars are produced using advanced Thermex technology from Hennigsdorfer Stahl Engineering GmbH, Germany, where controlled quenching and self-tempering create a tough, hardened outer layer and a softer, ductile core. This microstructure provides superior energy absorption under seismic and dynamic loading, while the optimized chemistry supports good weldability and corrosion resistance.

Key Features

• Fe 415 grade TMT bars providing high yield strength with safe elongation levels
• Ribbed 40 mm profile ensuring strong mechanical bond with concrete and reduced slippage
• Thermex-processed structure with tough martensitic rim and ductile core
• Stable mechanical properties and low residual stresses for better crack resistance
• Good weldability due to controlled carbon and alloy design
• Uniform sectional weight and length aiding accurate bar bending schedules

Applications

• Footings, columns, beams and slabs in RCC buildings
• Residential, commercial and industrial structures
• Infrastructure projects such as bridges, flyovers and metro structures
• Retaining walls, water tanks and other critical RCC elements
• General civil and structural engineering works
