The Birla TMT Fe 550 TMT Bar Birla Fe 550 TMT Bar - 8 mm is produced through the thermomechanical treatment process to comply with IS 1786:2008, delivering a 8 mm diameter bar in standard 12 m lengths with certified mechanical properties. With a guaranteed yield strength of 550 MPa and tensile strength of 585 MPa, this TMT bar is purpose-engineered for heavy structural RCC, bridge decks, and high-rise construction. Its ribbed surface profile provides excellent mechanical bond with concrete, while the controlled ductility of 10% elongation ensures structural safety under seismic and dynamic loading conditions.

• IS 1786:2008 Fe 550 grade with traceable strength and elongation test records
• QST process achieving 550 MPa yield with controlled 585 MPa tensile strength
• 10% elongation providing structural ductility at high-performance strength levels
• Higher yield enables reduced bar diameters and lighter reinforcement schedules
• Ribbed bar geometry for maximum concrete bond performance and anchorage depth
• Low carbon equivalent supporting field weldability without complex procedures
• Suitable for bridge deck slabs, heavy industrial floors, and high-rise columns
• 12 m standard lengths for efficient scheduling and site logistics management
• Reduces steel consumption and construction cost in heavily loaded RCC elements
• Preferred grade for infrastructure projects requiring high-strength reinforcing steel

• Long-span bridge pier reinforcement and foundation pile cage members
• High-strength column reinforcement in 20+ storey commercial buildings
• Pre-stressed concrete supplementary mild steel and compression zone bars
• Industrial chimney shafts, cooling tower shells, and silo wall reinforcement
• Power station civil structures including turbine foundation and crane girders
• Seaport and harbour jetty structures with high live load requirements
• Airport runway and taxiway pavement structural slab reinforcement
• Deep excavation basement slabs and heavily loaded raft foundations
