• Better bendability
• Adequate fire resistance
• Cost benefit
• Specially designed metallurgy developed in collaboration with Jadavpur University, Kolkata

Applications

• High-rise buildings
• Bridges
• Dams
• Hospital buildings
• School buildings
• Thermal and hydel power stations
• Other critical structures in seismic zones III, IV and V
