SAIL TMT EQR is a thermo-mechanically treated rebar with high ductility (UTS/YS ratio), higher and uniform elongation and a narrow range of yield strength. It is used for RCC in buildings, bridges and other concrete structures, and is particularly suitable for earthquake-prone zones.

Key features

• High ductility (UTS/YS ratio)
• Higher elongation and uniform elongation
• Narrow range of yield strength
• Excellent bendability
• Good weldability
• High fatigue resistance on dynamic loading

Applications

• Reinforced concrete construction (RCC) in buildings, bridges and other concrete structures
• Particularly suitable for earthquake-prone zones
