Import Dh36 Shipbuilding Steel Plate — Buy in Bulk from Supplier in China

DH36 shipbuilding steel plate is a high-strength, low-alloy structural steel designed for marine and offshore applications, with a minimum yield strength of 355 MPa and tensile strength between 490 and 620 MPa as per CCS and DNV standards. The plate is typically supplied in thicknesses ranging from 6 mm to 150 mm, with widths up to 4,200 mm and lengths up to 18,000 mm, conforming to standard rolling tolerances for structural plates. This grade is specifically engineered for hulls, decks, and bulkheads in vessels operating in icy or high-stress environments.

The material composition includes controlled levels of carbon, manganese, silicon, and small additions of niobium or vanadium to enhance toughness and weldability. It is manufactured under strict rolling and heat treatment protocols to ensure consistent mechanical properties across the plate. While the listing confirms compliance with CCS and DNV, it does not specify whether impact testing at -20°C is performed, which is standard for DH36 in many shipyards. The steel is typically supplied in normalized or thermomechanically controlled processed (TMCP) conditions to optimize grain structure.

This steel is commonly purchased by shipbuilders in Southeast Asia, Europe, and the Middle East for commercial vessels, offshore platforms, and ice-class ships. Buyers typically order in full plate quantities or cut-to-size lots, with packaging in steel strapping and protective film to prevent corrosion during transport. Trade terms are usually FOB Chinese port, with lead times averaging 30 to 45 days after deposit, though exact terms require direct confirmation with the supplier.

Zhengzhou City Jingying Iron And Steel Trade Co., Ltd. is an imported-tier supplier based in Zhengzhou, Henan Province, with a harbor trust tier indicating verified export activity. The company operates as a trading entity focused on structural steel products, sourcing from certified mills in China. The listing does not state whether it holds mill test certificates, maintains inventory, or has direct production capabilities. Response rate and average response time are not recorded, suggesting limited buyer engagement on the platform.

The supplier does not claim to be a manufacturer, nor does it list certifications such as ISO 9001 or third-party quality audits. Its profile reflects a standard trading intermediary with no disclosed history, workforce size, or client references. Buyers should treat this as a sourcing agent and request direct mill documentation for each shipment. The supplier's location in Henan places it near major steel distribution hubs, which may support logistics coordination.
