India's Premium Fe 550D Grade TMT Bar
We manufacture three grades under the Tusker TMT brand — each meeting or exceeding BIS IS 1786:2008 requirements.
High-strength Fe 550 grade TMT bars for projects requiring superior yield strength. A reliable choice for general construction, foundations, columns, and beams across residential and commercial projects.
Available Diameters
Fe 550D with enhanced corrosion resistance — the right choice for coastal zones, industrial environments, marine structures, and any project exposed to moisture, chlorides, or aggressive atmospheres.
Available Diameters
All grades available in cut-to-length. Contact us for grade-specific availability and pricing.
Tusker Fe 550D consistently exceeds BIS IS 1786:2008 standards in all key mechanical parameters. Our superior Thermex quenching process delivers higher yield strength, tensile strength, and elongation than the minimum required.
