Comprehensive mechanical, chemical, and physical property benchmarks for structural engineers and architects.
Avinashi Fe 500D is engineered specifically for structures exposed to dynamic dynamic loads and seismic zones. The 'D' designates extraordinary ductility, indicating an elongation percentage significantly higher than conventional rebars.
Its uniform tempered martensitic rim prevents brittle failures under extreme stress, while the ductile ferrite-pearlite core absorbs intense cyclic vibrations.
