AH36 Shipbuilding Steel Plate 6mm-650mm Thickness High Strength Structural Steel for Marine Vessels
AH36 shipbuilding steel plates are high-strength structural steel manufactured specifically for marine vessel construction. These hot-rolled plates offer superior tensile strength compared to conventional shipbuilding steel, enabling more efficient construction of large container ships, tankers, bulk carriers, and LNG carriers.

AH36 shipbuilding steel plates are primarily used for manufacturing ship hulls, bulkheads, upper decks, and hatch covers for various marine vessels including tankers, bulk carriers, container ships, and LNG carriers. High-strength grades like AH36 are particularly suited for high-stress areas of ships, providing equivalent strength with reduced thickness compared to general strength steel.
