Marine steel plate is specially designed for shipbuilding and offshore structures where high strength, excellent toughness, and reliable weldability are essential. Compared with ordinary structural steel, shipbuilding steel is manufactured under strict classification society requirements to ensure safe performance in demanding marine environments.

    China is one of the world's leading producers of marine steel plates, supplying products for commercial vessels, offshore platforms, port facilities, dredgers, barges, and marine engineering projects worldwide. Depending on the vessel type and structural requirements, different grades are selected to achieve the required strength, impact toughness, and welding performance.

    CEHE STEEL supplies a comprehensive range of Chinese marine steel plates, including A, B, D, E, AH32, AH36, AH40, DH32, DH36, DH40, EH32, EH36, EH40, FH32, FH36, and FH40. Plates are available in various thicknesses and dimensions, with flame cutting, CNC cutting, beveling, drilling, and customized processing services available for export projects.

    Marine steel plates can be supplied with certificates issued by major classification societies, including ABS, DNV, LR, BV, CCS, NK, KR, and RINA, together with EN 10204 3.1 Mill Test Certificates and third-party inspection upon request. Whether you are building new vessels or manufacturing offshore structures, our technical team can recommend the most suitable grade according to your project specifications and classification requirements.

1.How do I choose the right marine steel grade?

The right grade depends on the vessel type, structural location, service temperature, and the classification society requirements. Our technical team can recommend a suitable grade based on your project specifications and design drawings.

2.Which classification society certificates are available?

Marine steel plates can be supplied with certificates from major classification societies, including ABS, DNV, LR, BV, CCS, NK, KR, and RINA. EN 10204 3.1 Mill Test Certificates and third-party inspection reports are also available upon request.

3.Can marine steel plates be cut to custom sizes?

Yes. We provide flame cutting, CNC cutting, plasma cutting, drilling, beveling, and other processing services. Plates can be supplied according to your drawings or project requirements, helping reduce fabrication time at the job site.

4.What is the difference between AH36, DH36, and EH36 marine steel?

AH36, DH36, and EH36 have similar minimum yield strength but are designed for different impact test temperatures. AH36 is generally used in standard marine environments, while DH36 and EH36 are selected for colder operating conditions where higher low-temperature toughness is required.

5.Are marine steel plates suitable for offshore structures?

Yes. High-strength marine steel plates are widely used in offshore platforms, jack-up rigs, floating production units, offshore wind foundations, and other marine engineering projects where strength and toughness are critical.
