Product - INDOSTAR Fe 550D TMT Bar
Strength You Can Trust
INDOSTAR Fe 550D TMT Bar (Saria)
Strength in every rebar. Stability in every structure.
Indostar Fe 550D TMT Rebars are engineered to perform under the most demanding structural conditions. Crafted from molten iron into solid steel, Indostar rebars form the dependable backbone of modern construction, delivering long-term safety, strength, and peace of mind.
Galwalia Ispat Udyog (P) Limited manufactures Indostar Fe 550D TMT Rebars (Saria) at a fully integrated, automated steel plant. TMT stands for Thermo-Mechanical Treatment, a process that imparts superior strength and ductility to steel. Fe indicates iron-based steel and 550D denotes a minimum yield strength of 550 MPa with enhanced ductility. This combination ensures high load-bearing capacity, flexibility under stress, and excellent seismic performance.

Backbone of Construction
Indostar Fe 550D TMT Rebars are designed to be the backbone of reinforced concrete structures. Their exceptional strength, flexibility, and resistance to high stress make them ideal for residential, commercial, and infrastructure projects. The right selection of construction material, combined with proper structural design, ensures durability, safety, and lifelong performance.
Superior Manufacturing Process
Indostar TMT Rebars are produced in an eco-friendly, continuous integrated facility. Carefully selected and chemically tested raw materials are melted and cast into billets. These hot billets are directly rolled in a fully automated straight rolling mill equipped with German quenching technology. Controlled cooling on an automatic cooling bed ensures a fine grain structure, resulting in superior mechanical properties, durability, and uniform strength throughout the bar.
Applications of INDOSTAR Fe 550D TMT Bar
Indostar Fe 550D TMT Rebars are ideally suited for demanding structural applications where strength, flexibility, and resilience are critical. They are widely used in:
Key Advantages of Fe 550D TMT Rebar
Superior Strength Performance
Fe 550D grade rebars offer higher yield and tensile strength compared to conventional Fe 550 variants, making them ideal for heavy and complex structures such as dams, towers, flyovers, bridges, and industrial buildings.
High Ductility & Seismic Resistance
Enhanced flexibility enables the rebars to absorb and dissipate seismic energy, reducing the risk of structural failure during earthquakes.
Material & Cost Efficiency
Higher strength allows the use of fewer bars without compromising safety. This results in direct savings on steel consumption.
Reduced Labor & Construction Time
Fewer bars translate into faster placement, lower labor costs, and improved construction efficiency.
Excellent Weld ability
Low carbon, sulphur, and phosphorous content ensures superior weld ability without compromising structural integrity.
Enhanced Durability
Refined chemical composition provides better resistance to temperature variations, ensuring long-term performance in diverse climatic conditions.
Corrosion, Fire & Earthquake Resistance
Indostar Fe 550D TMT Rebars are designed to resist corrosion, withstand fire exposure, and perform reliably under seismic stress, safeguarding structures over their entire lifespan.
Cost Efficient by Design
Using the right construction material reduces long-term costs. While conventional TMT bars may fall short in physical, mechanical, or chemical properties, Indostar Fe 550D TMT Rebars deliver a balanced, BIS-compliant product. You get exactly what you pay for: consistent quality, reliability, and value over the lifecycle of the structure.
