JSW Neosteel Fe 550D EDS bars are made from Fe 550D grade with special chemistry and post-rolling treatment that make them more ductile and flexible than regular TMT bars. The high UTS/YS ratio of 1.15 minimum ensures higher energy absorption, and the bars are best suited to structural design for earthquake-prone zones. Rolled in 8-40 mm at Vijayanagar and 8-25 mm at Dolvi.

Key features

• Pure steel gives enhanced strength with durability
• Best-in-class rib pattern with highest AR value for bonding with cement
• Uniform quality across the bar (HYQST), seen as concentric rings in cross-section
• Absorbs higher earthquake energy than ordinary bars
• Easy weldability due to low carbon content
• Anti-corrosive
• Easy bendability due to soft ferrite and pearlite core
• Higher fatigue resistance for cyclic loads
• Green steel from zero-effluent-discharge plant, Green Pro certified

Applications

• Earthquake-resistant structures
• Structural design for earthquake-prone zones
