LR Grade DH62 is a high-strength, high-tensile shipbuilding steel plate with a yield strength of at least 620 MPa and an ultimate tensile strength of 740−890 MPa, certified by Lloyd's Register of Shipping. It is used in shipbuilding projects and offshore structural projects where high strength and toughness are required to withstand harsh marine environments, such as in ship hulls, decks, and superstructures.

LR Grade DH62 Shipbuilding Steel Plate Application
Hull Construction
LR Grade DH62 Marine Steel Plates are primarily used in building the hull structure of ships, including bulk carriers, oil tankers, container ships, and general cargo vessels.
The steel's high tensile strength and impact resistance ensure structural integrity under heavy loads, strong waves, and dynamic marine conditions.
Decks and Superstructures
Applied in the fabrication of ship decks, superstructures, and bulkheads, LR Grade DH62 ship plates maintain stability and load-bearing capacity while resisting deformation.
Offshore Engineering Structures
LR Grade DH62 offshore platform steel plate grades are also used in offshore platforms, drilling rigs, and floating production storage and offloading (FPSO) units.
Their ability to withstand low-temperature impact and harsh sea conditions makes them suitable for deep-sea oil and gas exploration projects.
Reinforcement and Safety Components
Utilized in critical parts of vessels, including keels, ribs, frames, and brackets, to provide additional strength and enhance the overall safety of ships.
LR Grade DH62 Shipbuilding Steel Plate Other Name
LR Grade DH62 Shipbuilding steel plate, LR Grade DH62 Ship steel plate, LR Grade DH62 Marine steel plate, LR Grade DH62 steel plate .
Additional Condition
