Shipbuilding and Offshore Platform steel plate

We supply marine and offshore steel plates certified by major classification societies, including ABS, LR, DNV, BV, CCS, KR, NK, RINA, GL and RMRS. Our shipbuilding steel plates are available in common strength, high strength and extra high strength grades, suitable for hull structures, offshore platforms, cruise ships and special vessels used in the oil and gas industry.

Shipbuilding steel plates are widely used in marine and offshore engineering. Thin and wide plates are commonly used in cabin structures of cruise ships, where good flatness and weldability are required.High-strength thermo-mechanically rolled shipbuilding plates are widely used in offshore structures, including platform superstructures, special vessels and equipment for the oil and gas industry.
