Dnv A420, Dnv D420, Dnv E420, Steel Plate
The product comprises DNV‑classified steel plates in grades A420, D420 and E420, supplied by Henan HZZ Iron and Steel Co., Ltd. in China. These plates are manufactured from high‑strength low‑alloy (HSLA) marine steel in a normalized condition, meeting DNV GL certification for shipbuilding applications. Thickness ranges are offered from 6 mm up to 50 mm, allowing custom dimensions to suit project drawings. The material delivers impact toughness and weldability required for hull structures.
In the marine steel market, HSLA plates of this class are standard for offshore platforms and large vessel hulls, where corrosion resistance and mechanical performance are critical. Typical tensile strength exceeds 550 MPa and yield strength around 355 MPa, aligning with international classification societies. The plates are usually supplied in coil or palletised sheets, with surface treatment to improve seawater resistance. Such specifications are typical for marine classification steel used globally.
Shipyards, offshore drilling contractors and marine equipment manufacturers are the primary buyers of these plates. Suppliers often provide flexible minimum order quantities and can ship under FOB or CIF incoterms from the Zhengzhou port. Packaging is designed for international transport, with steel pallets or coil wraps protecting against damage. Prospective importers should confirm exact dimensions, certification documents and payment terms directly with the supplier.

Sourcing Dnv A420, Dnv D420, Dnv E420, Steel Plate from Henan HZZ Iron and Steel Co., Ltd. - China Import Guide
Before placing an order, importers should request the DNV GL certification sheet and the ISO 9001 quality management certificate to verify compliance with marine classification standards. It is advisable to obtain a mill test report that details chemical composition and mechanical properties for the exact grade and thickness required. Confirm that the supplier can provide a signed declaration of material origin from the Zhengzhou facility.
Logistics for shipments from Henan typically involve inland transport to the nearest port, such as Tianjin or Shanghai, followed by ocean freight under FOB or CIF terms. Buyers should ask the supplier to state the expected lead time for cutting and preparing the plates, as this can vary with thickness and custom dimensions. Common payment methods include T/T in advance or LC at sight, but the exact terms must be agreed in the contract.
Quality assurance can be reinforced by arranging a third‑party inspection before loading, focusing on dimensional accuracy, surface condition and compliance with the DNV grade specifications. Request the supplier’s non‑destructive testing records, such as ultrasonic or radiographic reports, especially for thicker plates. Ensure that the final shipping documents include the certificate of origin, mill test report and a packing list that matches the order specifications.
