Key features

• Exceptional double rib design for a stronger interlock bond
• 2.5 times stronger concrete-steel interlock
• Advanced earthquake resistance
• Sulphur and phosphorus controlled (combined up to 0.075% per BIS for 500-D)
• Higher bonding strength with higher ductility
• Better ductility, bendability and weldability
• Higher thermal stability (400 to 600 degrees)
• Anti-corrosive properties
• High elongation values, excellent workability
• Fe-550 grade reduces steel consumption (claimed 9% saving vs Fe-500, 25% vs Fe-415 in columns)

Applications

• Bridges
• Flyovers
• Dams
• Thermal and hydel plants
• Industrial towers
• Skyline / high-rise buildings
• Underground platforms
• Earthquake-resistant construction
