Product Description
Vizag Steel TMT Bars—high-performance reinforcement bars produced by RINL (Rashtriya Ispat Nigam Ltd), a renowned Navaratna PSU under the Ministry of Steel. These TMT bars are engineered with advanced Thermo-Mechanical Treatment (QST), delivering a robust martensitic exterior over a ductile ferrite–pearlite core—combining exceptional strength, resilience, and flexibility.
Why Choose Vizag Steel TMT Bars?
- Outstanding Strength & Ductility: With a tensile-to-yield strength ratio consistently above 1.12 (often exceeding 1.15), these bars offer superior load resistance while maintaining high elongation—ideal for earthquake-resistant structures. :contentReference[oaicite:0]{index=0}
- Exceptional Corrosion Resistance: Thanks to a tempered exterior, absence of eutectoid carbides, and a protective scale layer, these rebars resist rust even in coastal or high-humidity environments. :contentReference[oaicite:1]{index=1}
- Superior Bend & Re-bend Capability: The unique balance of a tough outer skin and flexible core enables bending—even around tight mandrels—and reliable re-bending, with minimal risk of cracking or strain aging. :contentReference[oaicite:2]{index=2}
- Weldability & Fabrication Ease: Lower carbon content ensures excellent weldability across various methods—arc welding, flash butt welding, resistance welding—without sacrificing strength. :contentReference[oaicite:3]{index=3}
- Consistent Quality & Wide Availability: Available in sizes ranging from 8 mm to 32 mm (and up to 40 mm in some grades), all bars meet rigorous IS 1786 standards under strict quality control. :contentReference[oaicite:4]{index=4}
Recommended Applications:
- Critical infrastructure: Bridges, flyovers, dams, highways, and industrial buildings requiring high strength and ductility. :contentReference[oaicite:5]{index=5}
- Residential and commercial structures: Foundations, columns, beams, and slabs—especially where long-term durability is vital.
- Buildings in seismic or coastal regions: Enhanced flexibility and corrosion protection make them a top choice for challenging environments. :contentReference[oaicite:6]{index=6}
