Henan HZZ Iron and Steel Co., Ltd. supplies GL‑graded carbon structural steel plates designated A420, D420 and E420 for marine construction. The plates are produced to Germanischer Lloyd and DNV GL classification standards, ensuring impact toughness and weldability required for hulls and offshore structures. Thicknesses are available from 6 mm up to 80 mm and widths can reach 4 000 mm, with options of cut‑to‑length pieces or wound coils for efficient handling. All plates are supplied as hot‑rolled, mill‑finished material and carry the GL grade markings required by shipyards.
These GL grades belong to the carbon structural steel family, where typical tensile strength ranges between 460 MPa and 550 MPa and yield strength between 260 MPa and 350 MPa, depending on the specific grade. Standard industry tolerances for thickness are ±0.5 mm and impact energy of 27 J at - 20 °C is commonly required for marine applications. The material composition conforms to the usual carbon steel limits of up to 0.25 % carbon, with manganese and silicon as alloying elements, matching the specifications of most Asian mill sources. Such plates are routinely used by shipyards that demand consistent mechanical properties and certification to GL standards.
Buyers typically include shipbuilding contractors, offshore platform fabricators and marine equipment manufacturers who source in bulk and require FOB or CIF terms to major Chinese ports. Minimum order quantities are not fixed by the supplier and can be discussed directly, allowing flexibility for projects of varying scale. Importers should confirm the exact grade, thickness tolerance, certification documents and agreed Incoterms with Henan HZZ before placing an order.

Before placing an order, importers should verify that the steel plates carry the correct GL grade, thickness tolerance and certification documents such as mill test reports and GL classification certificates. Request a sample of the test report to confirm mechanical properties and impact energy values match the typical specifications listed. Ensuring these documents are in place reduces the risk of receiving non‑conforming material.
Logistics for these plates are usually arranged on FOB or CIF terms to major Chinese ports; buyers need to confirm the exact Incoterm, port of loading and expected lead time with Henan HZZ. Payment terms are commonly negotiated on a letter of credit or telegraphic transfer basis, but the final arrangement should be documented in the purchase contract. Clarifying these trade terms early helps align production schedules with shipyard timelines.
Quality assurance commonly includes a third‑party inspection at the factory before shipment, focusing on grade verification, dimensional checks and surface condition. Importers should arrange for an inspection agency to issue an inspection report and, if required, a certificate of compliance. Collecting all relevant certificates and inspection reports will streamline customs clearance and ensure the material meets the project specifications.
