Suryadev TMT Fe 500D rebars are thermo-mechanically treated reinforcement bars designed to provide high strength, reliable ductility and stable performance in RCC structures. The 20 mm bar size offers an excellent balance between load-carrying capacity and steel consumption, making it suitable for a wide range of primary and secondary reinforcement needs.

Manufactured from quality billets in modern automated mills, the bars feature a tough tempered outer layer with a softer, ductile core, giving superior energy absorption under seismic and dynamic loading, along with controlled chemistry and ductility levels that exceed conventional Fe 500 bars, and enhanced corrosion resistance for structures exposed to moisture, chlorides or aggressive environments. Low levels of harmful impurities and consistent rib geometry ensure dependable bond with concrete and good weldability.

Key Features

• Fe 500D grade providing high yield strength with reliable elongation
• Corrosion resistant chemistry for extended service life in coastal and aggressive environments
• Precisely rolled 20 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
