ARS TMT Fe 550D rebars are engineered to combine high strength with excellent ductility, supporting safer and more durable RCC design. The 8 mm diameter section provides strong bond with concrete and allows economical spacing and detailing in beams, slabs and columns.

Using corrosion-resistant steel (CRS) technology with optimised additions of elements such as chromium, nickel and molybdenum, these bars significantly reduce rusting and pitting in chloride- or moisture-rich environments. A carefully controlled TMT process produces a tough martensitic surface and ductile core, improving fatigue resistance and performance during earthquakes.

Key Features

• Fe 550D grade providing high yield strength with reliable elongation
• Corrosion resistant chemistry for extended service life in coastal and aggressive environments
• Precisely rolled 8 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
