Corrosion-resistant steel, add wings to Walvis Bay


Located in the middle of Namibia's coastline, Walvis Bay is directly integrated into international shipping routes and is the country's largest commercial port. Due to the increase in domestic cargo throughput, upgrading its infrastructure is imminent.

 

The Namibian coastline has high salt fog, high salt soil, and periodic eruptions of hydrogen sulfide gas on the ocean surface. Metal and concrete building structures can be quickly corroded if proper measures are not taken. In this case, the only hope is steel.

 

ASTM A131 Grade DH32 shipbuilding and offshore steel plate is a corrosion resistant steel suitable for marine port construction.
ASTM A131 Grade DH32 shipbuilding and offshore steel plates are mainly used in the manufacture of hull, deck, offshore platforms, etc. BBN ASTM A131 Grade DH32 shipbuilding steel plates have been approved by international classification societies,such as ABS, LR, GL, CCS, NK, DNV, BV, RINA, KR, RMRS.
