DNV D32, DNV D36, and DNV D40 are high-strength, hot-rolled carbon steel plates certified for marine and offshore structural use. These grades are produced in thicknesses from 6mm to 50mm and are designed for hull plating, deck structures, and offshore wind turbine foundations. The material meets DNV GL standards for low-temperature toughness, weldability, and tensile strength, making them suitable for vessels operating in Arctic or North Sea conditions.
These plates are manufactured using controlled rolling and accelerated cooling to achieve fine-grained microstructures. D32 has a minimum yield strength of 315 MPa, D36 is 355 MPa, and D40 is 390 MPa. All grades are impact tested at -20°C, with minimum energy values of 27J for D32 and D36, and 34J for D40. The steel contains low sulfur and phosphorus to reduce segregation and improve weld integrity. Surface finish is typically mill scale, unless specified otherwise.
Buyers include shipbuilders, offshore module fabricators, and renewable energy contractors constructing floating platforms and wind turbine support structures. Orders are commonly placed with mill test certificates, and plates are packed in steel-strapped bundles with moisture-resistant paper. Delivery is typically FOB Chinese ports, with lead times of 25 to 40 days. Payment terms often involve 30% advance and 70% against shipping documents.

Henan HZZ Iron and Steel Co., Ltd. is registered in Zhengzhou, Henan Province, China, and is listed as an imported supplier with harbor-tier verification. The company functions as a trading intermediary for DNV-certified steel plates, with no disclosed manufacturing facility or mill ownership. The profile provides no information on production volume, workforce, or years of operation, and no direct quality control systems are referenced.
The supplier's contact address is a commercial office, not a production site. There is no indication of in-house testing equipment, certified weld procedures, or direct relationships with steel mills. Buyers should treat this entity as a sourcing agent that arranges export logistics and documentation for material sourced from third-party mills, likely in China or neighboring countries.
DNV certified shipbuilding steel plates in grades D32, D36, and D40 are hot-rolled high-strength plates designed for marine vessel hulls, offshore platforms, and offshore wind structures. These DNV-approved grades offer superior weldability and impact toughness at low temperatures, meeting rigorous classification society standards for maritime applications. Widely sourced from mills in China, South Korea, and Japan, these plates are traded globally for newbuild ship construction and naval engineering projects, typically supplied in thicknesses of 6-50mm with standard export packaging.

Before ordering, confirm the mill test certificate includes heat number traceability, chemical analysis, and mechanical test results for each batch. Ensure the certificate is issued by an accredited lab and matches the DNV classification standard. Do not accept generic certificates lacking test data or with unverified signatures. Verify the supplier can provide the original document, not just a copy.
Confirm the Incoterms, typically FOB Shanghai or Qingdao, and clarify whether the supplier handles export customs clearance. Lead times are generally 25 to 40 days, depending on mill availability. Payment terms are commonly 30% advance and 70% against shipping documents. Request confirmation of the vessel’s loading port and estimated departure date in writing.
Upon delivery, inspect for surface cracks, scale spalling, and dimensional accuracy. Use a hardness tester to verify consistency across the plate. Retain samples for independent lab testing of yield strength and impact energy. Request the original mill certificate and verify its authenticity with DNV’s online portal using the heat number. Reject any plate with missing or altered documentation.
