This series of steel plates are high-performance structural steels specially used for ship hulls, decks, superstructures and offshore oil & gas platforms. Produced by ultra-clean smelting, controlled rolling and professional heat treatment, the products feature high strength, excellent low-temperature toughness, superior seawater corrosion resistance, outstanding fatigue resistance and reliable weldability. They can adapt to harsh marine environments, withstand long-term alternating loads, wave impact and complex climatic conditions. Certified by major international classification societies, these steel plates are widely applied in commercial ships, engineering vessels, offshore drilling platforms, production platforms, offshore wind power structures and other marine engineering facilities.
