ARS Fe 550D CRS TMT Bar - 36 mm

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.

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 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
