JSW Neosteel Fe 550D CRS is a high-strength corrosion-resistant TMT re-bar used in coastal areas, high-salinity or high-acid air zones, industrial areas and marine structures. Rolled in 8-40 mm at both Vijayanagar and Dolvi. Extra Cu (0.20-0.25 %) and Cr (0.45-0.55 %) are added in CRS grades.

Key features

• Longer life and lowest cost over the life span
• Higher weldability than ordinary rebars
• More flexibility
• high yield strength coupled with higher ductility and bendability
• Better fire resistance
• Increases life expectancy of structures by 1.5 to 1.7 times
• Better performance in seismic zones
• Additional Cu (0.20-0.25 %) and Cr (0.45-0.55 %) added in CRS grades

Applications

• Coastal areas
• Areas with high salinity in the air
• Industrial areas
• Marine structures
• Areas with high acid content in the air
