• LR, ABS, NK, GL, DNV, BV, KR, RINA, CCS,DH36 Shipbuilding steel plate
  • Capable Classification Society Quality Authentication from LR, ABS, NK, GL, DNV, BV, KR, RINA, CCS,DH36 shipbuilding steel plate is used for shipbuiling&platform.The shipbuilding steel plate grade DH36 is the high tensile strength steel.DH36 shipbuilding steel is the Hull structural steel,with it s good toughness properties, higher strength,strong corrosion-resistance,the processing properties,and welding properties.ASTM A131 DH36 steel plate  can be used in the manufacture of the ship s hull structure whose weight is more than 10000 tons.

    ABS DH36 Shipbuilding Steel Specification:
    Thickness: 4mm to 260mm,
    Width: 1200mm to 4000mm
    Length: 3000mm to 18000mm.

    ABS DH36 Shipbuilding Steel Application:
    ABS DH36 Shipbuilding steel plates are mainly used for making the offshore oil drilling platform, the hull of ship building and ship repairing, the platform pipe joints and other components.
