ARS TMT Fe 550D rebars are engineered to combine high strength with excellent ductility, supporting safer and more durable RCC design. The 36 mm diameter section provides strong bond with concrete and allows economical spacing and detailing in beams, slabs and columns.

Produced in fully integrated facilities with rigorous quality control, the bars develop a tough outer martensitic rim and ductile core that provide superior energy absorption under seismic and cyclic loading. Uniform rib pattern and low impurity levels ensure strong bond with concrete, good weldability and consistent mechanical properties along every metre.

Key Features

• Fe 550D grade providing high yield strength with reliable elongation
• Enhanced ductility class for improved crack resistance and better seismic performance
• Precisely rolled 36 mm ribbed profile ensuring strong mechanical interlock with concrete
• Thermo-mechanically treated structure with tough outer layer and ductile core
• Low carbon and controlled alloy additions enabling good weldability
• Uniform sectional weight and length aiding accurate bar bending schedules and optimisation of steel usage

Applications

• Footings, columns, beams and slabs in RCC buildings
• High-rise and commercial structures requiring ductile detailing
• Industrial sheds, warehouses and factory foundations
• Infrastructure projects such as bridges, flyovers and metro structures
• Water tanks, retaining walls and other critical RCC components
