    Join the Corrosion Resistance movement. ARS 550D CRS is here!

    It is here. A TMT Bar that retains its ductility while being corrosion and earthquake resistant. All thanks to the micro alloys, Copper, Chromium, Nickel and Molybdenum, added to the steel at optimal quantities.

    • ARS 550D CRS can increase the life of any structure. It is much more imperative under certain specific conditions.
    • 550D CRS is Highly recommended if the salt content in the ground water is >300 ppm.
    • Seaside structures – Reduces the diffusion of chloride ions in TMT Bars on TMT bars.
    • Super structures of all type of the buildings since it reduces corrosion related problems.

    Specifications that ensure truly strong structures!

    • Highest Corrosion Resistance CRE -0.5% Min
    • High Earthquake Resistance – Ductility 16 to 18%
    • High Strength/Grade 560 N/mm2 to 600 N/mm2
    • Highest Bonding with concrete – innovative angular lugs
    • Increases the life/durability of building by 3 times
    • Higher fire resistance – FRE – 0.18

    True benefits of ARS 550D CRS

    • Higher Corrosion Resistant Equivalent (CRE), average 0.5 % (20% higher than the IS 1786- 2008).
    • Highest resistance to FIRE as the micro alloys increase the Fire resistance equivalent.
    • Reduced rate of corrosion of steel during and after the construction increases the life of the structure.
    • Increases the life of the structure by 3 times (with optimal construction practices).
