We have abundant supply experience. We have been supplied our offshoreuse steel plates all of the world.
The AB/EQ70 is a super high strength steel grade. The test temperature of this steel grade is -40. It is used in offshore drilling platforms, shipping engineering and shipbuilding projects. We are able to provide normal strength, high strength, and super high strength shipbuilding steel plates. Customization of DNV Grade A shipbuilding steel, DNV Grade A steel stock DNV Grade A marine steel plates can be used for ship repairing, the offshore oil drilling platform, the platform pipe joints and other components. DNV Grade A grades of steel plate are almost exclusively used in the shipbuilding Industry for the construction of structural parts of DNVGL-OS-B101 Metallic materials - Rules and specify procedures and requirements to metallic materials to be used in offshore structures and facilities subject to DNV GL certification and classification. 1.2 Scope and application 1.2.1 The requirements are applicable to: rolled steel for structural applications steel pipes forgings and castings wrought aluminium alloys.
Shipbuilding and Offshore Structural Steel Plate is mainly used to Ship Project and Ocean Offshore Structural Project. ABS,LR,DNV,BV,GL,CCS,KR,NK,RINA,ASTM A131, EN10225 .
