1. What is Shipbuilding Steel Plate?
Shipbuilding steel plates, also known as marine steel plates or shipbuilding plates, are specialised hot-rolled steel plates manufactured in accordance with classification society standards and used exclusively for the construction of ship hulls and offshore engineering structures. The core requirements for these plates are high strength, high toughness, good weldability and resistance to seawater corrosion, and they must be certified by international classification societies. As a key material in the global shipbuilding industry, it must be capable of withstanding harsh marine conditions, such as high mechanical stresses, extreme temperatures, alternating wave loads, and prolonged exposure to a corrosive seawater environment.
Shipbuilding steel plates are generally produced from high-strength low-alloy steel (HSLA) or low-carbon steel, offering excellent weldability, formability and low-temperature toughness, thereby ensuring the long-term structural integrity and durability of the vessel.

3. Classification Society Certification
Shipbuilding steel plates are manufactured in accordance with the standards of various classification societies, and the steel must be certified by a classification society before it can be used in shipbuilding.
We guarantee that all our shipbuilding steel plate products are manufactured in strict compliance with the highest safety and quality standards, and that they have all been certified by the relevant classification societies.

8. Applications
Bulk Carriers and Oil Tankers:
- AH36 is commonly used for hull plating, whilst Class B plates are predominantly used for bulkhead plating; for less critical structural components, standard-strength plates such as Classes A, B, D and E are also widely used.
Large Container Ships:
- These vessels place high demands on components such as decks and side frames, requiring high-strength plates such as EH40 and FH40 to withstand the high torsional and stress loads caused by stacked containers.
Offshore platforms and FPSO:
- The legs of jacket platforms generally utilise high-strength plates such as S420QL, with a yield strength of ≥460 MPa; the decks of Floating Production, Storage and Offloading (FPSO) vessels commonly employ ship plates with excellent fatigue resistance, such as FH40.
