Products FAQ

Yes. All of our LR Grade DH36 marine steel plates hold valid official certification from Lloyd’s Register and are accompanied by authoritative EN 10204 3.2 mill test certificates (MTC).

All certificates are globally recognized and support international shipyard tenders, acceptance inspections for offshore projects in extremely cold regions, and cross-border customs clearance.

Yes. LR DH36 marine structural steel plate is the premier material of choice for primary and secondary load-bearing structures on offshore platforms.

Its ultra-high strength, excellent low-temperature toughness, and resistance to seawater corrosion make it fully suited to harsh marine operating environments and meet the high standards for safety and durability in offshore engineering.

Common delivery conditions include: AR (hot-rolled), TMCP (thermomechanically controlled rolling), and normalized (N).

Steel plates thicker than 50 mm are typically required to be delivered in the normalized or TMCP condition.

Special heat treatments can be customized according to LR specifications and customer technical requirements. Thickness-direction strength grades Z15, Z25, and Z35 are available.

We provide one-stop value-added processing services, including precision cutting, bending, drilling, beveling, surface rust removal, shot blasting, anti-corrosion coating, and heat treatment, to fully meet the customized manufacturing needs of offshore engineering projects in cold regions.

Yes. All of our LR Grade DH32 shipbuilding steel plates fully support inspections by internationally recognized third-party organizations such as SGS, BV, and DNV. They come with complete official LR certification and original factory test reports, ensuring comprehensive quality traceability.

LR DH32 has a minimum yield strength of 315 MPa and is suitable for offshore projects with moderate loads; it offers better weldability and lower costs. LR DH36 has a minimum yield strength of 355 MPa and is suitable for heavy-duty deep-sea projects. LR DH32 is more cost-effective for traditional offshore structures in temperate waters with moderate load requirements.

Yes. Our LR Grade DH32 marine steel plate fully complies with the relevant marine steel standards of major classification societies, including CCS, ABS, BV, DNV, and NK. We can provide dual or multiple classification society joint certifications based on customer requirements to meet the acceptance standards for ships and offshore engineering projects in cold waters across different countries and regions.

We provide one-stop value-added processing services, including precision cutting, bending, drilling, beveling, surface derusting, shot blasting, anti-corrosion treatment, and heat treatment, to meet all custom manufacturing and installation requirements for high-standard offshore engineering projects.

Yes. All of our LR Grade AH36 shipbuilding steel plates fully support third-party inspections by internationally recognized organizations such as SGS and BV. They come with complete official LR certification and original factory test certificates, ensuring comprehensive quality traceability.

LR Grade AH36 shipbuilding steel plate is a high-strength hull structural steel certified by Lloyd’s Register (LR). It is primarily used in ultra-large ocean-going vessels, deep-sea offshore platforms, heavy-duty offshore engineering facilities, and high-load-bearing ship structures, and serves as a core load-bearing material for high-grade offshore engineering projects.
