ARS 550D CRS

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 water on TMT bars.
Super structures of all type of the buildings since it reduces corrosion related problems.

Features that make ARS 550D CRS unique

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).
