TMT Bars

GTT 500 TMT Bars

Fe 500 TMT bars are a popular grade used in construction for their balance of strength and ductility.

They are ideal for:
  • Residential & commercial buildings
  • Bridges and flyovers
  • Industrial structures
Specifications:
  • Yield Strength: 500 N/mm²
  • UTS: ~545 N/mm² or higher
  • Sizes available: 8mm, 10mm, 12mm, 16mm, 20mm, 25mm, 32mm
  • Standard Length: 12 meters (can vary)
  • Standards followed: IS 1786:2008 (BIS certified)

GTT 500D TMT Bars

🔧 Key Specifications of 500D TMT Bars:
Grade Fe 500D
Yield Strength Minimum 500 N/mm²
Tensile Strength/ Minimum 565 N/mm² (≥ 8% more than yield strength)
Elongation Minimum 16%
Bend Test Excellent bendability and rebend properties
Carbon Content Lower than Fe 500 (for better weldability and ductility)
🛠️ Appliations of 500D TMT Bars:
  • High-rise buildings
  • Dams and bridges
  • Industrial and infrastructure projects
  • Coastal and seismic zones
  • Residential construction where safety and durability are priorities

GTT 550D TMT Bars

🛠️ Features of Fe 550D TMT Bars:
  • Higher Strength: Offers 10% more yield strength than 500D, reducing steel consumption.
  • Great Ductility: Despite higher strength, ductility remains high — ideal for earthquake-resistant construction.
  • Superior Weldability: Thanks to lower carbon content and micro-alloying.
  • Corrosion & Fire Resistant: Uniform and tempered outer layer improves resistance to rust and high temperatures.
  • Cost-Efficient: Requires less steel per project due to its higher strength.
🏗️ Applications:
  • Metro and railway projects
  • High-load infrastructure (bridges, flyovers, industrial sheds)
  • Multi-storey buildings and skyscrapers
  • Marine and coastal construction zones
  • Earthquake-prone regions
