Why Corrosion Resistance Matters in Coastal & Marine Construction


Coastal cities like Mumbai, Chennai, Kochi, Visakhapatnam, and Goa face high humidity and salt-laden winds that accelerate steel corrosion, compromising structural longevity. When building jetties, ports, bridges, or sea-facing buildings, using corrosion-resistant AMBA Shakti SD and Flexion TMT Bars ensures durability, superior ductility, and earthquake safety.

AMBA Shakti SD TMT Bars: A Super Ductile Solution for Coastal Projects


  • Engineered for harsh environments using HSS rolls, which produce a protective oxide layer for enhanced corrosion resistance.

  • Features no-twist straight mill rolling and CNC notching, ensuring distortion-free bars and strong bonding with concrete, critical in salt-exposed coastal structures.

  • Employs hot charging, PLC-based automation, and a sand filtration quenching process—delivering about 20% steel cost savings, premium finish, and extended roll life (Amba Shakti).

  • Ideal for coastal residential projects, fishing harbours, and waterfront resorts.



AMBA Shakti Flexion TMT Bars: Built for Mega Coastal & Marine Infrastructure


  • Manufactured via the Ladle Refining Furnace (LRF), refining steel chemistry by eliminating impurities and ensuring enhanced purity and flexibility.

  • Offers enhanced seismic resistance, perfect for large-scale marine projects like sea bridges, dams, airports, and naval bases.

  • Cost-efficient with quality comparable to premium alternatives (Amba Shakti).

FAQ Section 

Q1. What gives AMBA Shakti bars superior corrosion resistance? 

During production, they form a natural oxide layer and use HSS rolls, both significantly enhancing protection in humid or saline climates.


Q2. Which bar type is best for mega coastal infrastructure? 

Flexion, thanks to its LRF route manufacturing, attains purer chemistry and better seismic resistance, ideal for large-scale marine applications.


Q3. Do they handle earthquakes, too? 

Yes, both types are super ductile with features like CNC notching for enhanced concrete bonding, making them earthquake-safe.


Q4. What builds confidence in AMBA Shakti quality? 

Tempcore® certification, hot charging automation, and ISO/BIS accreditations underpin high-quality and consistent products.
