DNV A420, DNV A460, DNV A500, Steel Plate
Henan HZZ Iron and Steel Co., Ltd. supplies DNV‑certified carbon‑manganese shipbuilding steel plates in grades A420, A460 and A500. These plates are produced from hot‑rolled carbon‑manganese alloy steel and are classified for marine hull construction. Yield strengths range from 420 MPa for grade A420 up to 500 MPa for grade A500, with higher grades such as A550 and A620 commonly available from the same mills. Thicknesses are normally offered between 8 mm and 60 mm.
The plates meet DNV GL classification, delivering the tensile and impact performance required for commercial and naval vessels. Typical chemical makeup includes carbon 0.20‑0.30 %, manganese 0.80‑1.10 % and controlled levels of silicon, sulphur and phosphorus, aligning with standard shipbuilding steel specifications. Standard tensile strength for these grades lies between 550 MPa and 750 MPa, and the material is supplied with a mill‑finish surface ready for welding. These attributes make the plates suitable for high‑stress structural components such as keel, bulkheads and deck plating.
Target customers are shipyards, offshore platform fabricators and defence contractors that need high‑strength hull plates. The supplier is listed as an imported tier with a harbour trust rating, but does not disclose MOQ, price or exact lead time, so these must be clarified with the company. Trade terms, including Incoterms and payment methods, are negotiable and should be confirmed before contract signing. Requesting the DNV certificate and mill test documentation is essential for compliance with classification societies.

| Width | up to 2500 mm (typical maximum width) |
| Length | up to 12 m (typical) |
| Tensile Strength | 550 MPa - 750 MPa (typical) |
| Surface Finish | Mill finish (standard) |
| Chemical Composition | C 0.20‑0.30 %, Mn 0.80‑1.10 %, Si ≤0.30 %, S ≤0.035 %, P ≤0.035 % (typical) |

Henan HZZ Iron and Steel Co., Ltd. operates from Jincheng International Building 6 in Zhengzhou, Henan Province, China, and specialises in the production of carbon‑manganese steel plates for marine engineering.
The firm is recorded as an imported‑tier supplier with a harbour trust rating on the platform. While the listing does not provide response statistics beyond a 0 % response rate, buyers can expect verification of the company's registration through the supplied address. Details such as minimum order size, pricing and delivery schedule are not disclosed and should be obtained directly from the company.
DNV graded shipbuilding steel plates including A420, A460, A500, A550, A620, and A690 are high-strength structural plates certified by DNV GL for marine vessel hull construction and offshore platform applications. These hot-rolled plates comply with DNV classification society standards and offer yield strengths ranging from 420 to 690 MPa depending on grade, making them suitable for critical load-bearing structures in commercial and naval shipbuilding. Widely sourced from mills in China, Japan, and South Korea, DNV marine plates are traded globally with standard export packaging for ocean freight.

Sourcing DNV A420, DNV A460, DNV A500, Steel Plate from Henan HZZ Iron and Steel Co., Ltd. - China Import Guide
When ordering these high‑strength plates, importers should verify the required grade, thickness and dimensions, and obtain the DNV GL certificate along with a mill test report that confirms the mechanical properties and chemistry. Confirming that the mill finish matches the welding procedure is also advisable.
The supplier’s location in Zhengzhou allows for rail or container transport to major Chinese ports. Since the listing does not specify lead time or Incoterms, buyers need to agree on terms such as FOB Zhengzhou or CIF Shanghai and settle on payment methods like L/C or T/T. Early contact is recommended because the platform records a zero‑percent response rate for this supplier.
Arranging a third‑party inspection either at the mill or on arrival can ensure that thickness, flatness and surface condition meet project specifications. Retaining the mill test certificate and DNV classification documents will facilitate customs clearance and classification approval. Proper documentation reduces the risk of delays for shipyard projects.
