Shyam TMT Re-bars Fe 500 is a special higher-strength grade produced under specific process conditions, giving increased tensile strength compared with Fe 415/415 D. It suits heavy-load RCC structures such as flyovers, dams and bridges where a high yield load is needed without sacrificing ductility.

Key features

• Special weldability: no pre- or post-weld treatment (low carbon, controlled thermo-mechanical treatment)
• Higher corrosion resistance and fatigue strength from a uniform, thick tempered martensitic rim (thicker than Fe 415/415 D)
• Higher tensile strength than Fe 415/415 D, so lower steel consumption: about 17 % effective saving compared with Fe 415 (1.00 MT of Fe 415 steel replaced by 0.83 MT
• 170 kg saved)
• Also carries the features of Shyam Fe 415/415 D TMT re-bars

Applications

• Heavy-load RCC structures such as flyovers, dams and bridges
• Power plants
• High-rise buildings
• Other critical structures requiring high yield load without loss of ductility
