Rolling ISI Fe 550D TMT bars pair 550 MPa yield strength with D-class ductility, offering both high load capacity and superior elongation for safety-critical RCC. With controlled chemistry and thermo-mechanical treatment, they combat corrosion, hold integrity under fire exposure, and perform exceptionally in earthquake-prone zones—ideal for metros, long-span bridges, high-rise cores, coastal works, and heavy civil structures.

Key Features:

• Very High Strength + High Ductility (D-Class)
• Excellent Weldability
• Fire Resistance
• Corrosion Resistance
• Exceptional Seismic Energy Absorption
• Enhanced Bonding for crack-resistant RCC interfaces
