TMT Bars
High-Strength TMT Rebars for Earthquake-Resistant RCC Construction
Amari Industries is an authorized dealer and stockist of primary Fe 500D, Fe 550D, and Corrosion Resistant Structural (CRS) TMT bars. Manufactured with Tempcore/Thermex German quenching technology for high bendability, superior bond strength, and seismic resilience.
Thermo-Mechanically Treated
Ribbed Reinforcement Rebars
TMT Structural Reinforcement Grades
Engineered through controlled water quenching (Tempcore process) to yield a tough, tempered martensite outer rim and a ductile ferrite-pearlite core.
Fe 500D (High Ductility)
Specially formulated with an enhanced elongation capacity (≥ 16%) for seismic zones III, IV, and V. Outstanding energy absorption during earth tremors.
Residential high-rises, commercial towers, hospitals, schools, and bridges.
Fe 550D (Heavy Load)
High-strength grade that reduces steel consumption by up to 8-10% in heavily reinforced sections, reducing rebar congestion in beams and columns.
Metro flyovers, expressways, deep foundation raft slabs, heavy industrial PEBs.
Fe 500D CRS (Corrosion Resistant)
Alloyed with Copper (Cu), Chromium (Cr), and Phosphorus (P) to produce a dense passive oxide barrier that shields the inner steel matrix from saltwater and acids.
Coastal jetties, marine structures, chemical plants, effluent treatment plants.
Primary & BIS Approved TMT Brands
All rebars are supplied with manufacturer batch tags, branded rib markings, and matching test certificates.
Mechanical & Dimensional Specifications
Every bundle supplied by Amari Industries conforms to strict nominal mass tolerances and mechanical elongation properties.
