Birla TMT Fe 550 TMT Bar Birla Fe 550 TMT Bar - 12 mm is a high-strength thermomechanically treated reinforcing steel bar produced to IS 1786:2008, featuring a 12 mm nominal diameter in standard 12 m mill lengths. Delivering a minimum yield of 550 MPa, tensile strength of 585 MPa, and elongation of 10%, this bar is designed for heavy structural RCC, bridge decks, and high-rise construction where reliable load transfer and ductility are critical. The distinct transverse and longitudinal rib pattern ensures maximum mechanical interlock with concrete, reducing slip and enhancing structural integrity in reinforced concrete members.

• Fe 550 IS 1786:2008 certified TMT bar with guaranteed high-strength properties
• Thermomechanical treatment for 550 MPa yield with adequate elongation reserve
• Yield 550 MPa and UTS 585 MPa for heavy-duty structural concrete applications
• 10% elongation ensuring minimum ductility in high-strength reinforcing members
• Ribbed surface ensuring composite action and full anchorage in structural concrete
• Site-weldable with standard procedures following IS 1786 chemical requirements
• Enables steel-optimised designs in bridge decks, industrial slabs, and columns
• Standard 12 m lengths simplifying procurement, transport, and site handling
• Preferred for long-span slabs, heavy beams, and high-axial-load columns
• Supports value engineering and material cost reduction in large-scale projects

• Primary reinforcement in high-rise commercial and residential towers
• Major bridge structures: deck slabs, abutments, and pier foundations
• Pre-cast heavy beams, double-tee slabs, and long-span structural elements
• Industrial harbour structures, dry docks, and marine concrete foundations
• Long-span flat plate floor systems in commercial and mixed-use buildings
• Heavily loaded raft slabs and piled raft foundations in soft ground
• High-axial-load column cages in multi-use tall building podium levels
• Critical civil works in power, petrochemical, and heavy industrial plants
