Classification Societies and Steel GradesClassification Societies:

ABS (American Bureau of Shipping), BV (Bureau Veritas), CCS (China Classification Society), DNV GL (Det Norske Veritas Germanischer Lloyd), KR (Korean Register of Shipping), LR (Lloyd's Register), NK (Nippon Kaiji Kyokai) are renowned organizations that set strict standards for the quality and performance of steel used in ship and bridge building. These standards ensure the safety and durability of the structures.

Dh32 and Dh36: These are high - strength ship - and bridge - building steel grades. The numbers (32 and 36) represent the minimum yield strength values (in ksi - kilo - pounds per square inch). Dh32 has a minimum yield strength of 32 ksi, and Dh36 has a minimum yield strength of 36 ksi. They are designed to withstand the heavy loads and harsh environmental conditions associated with marine and bridge applications.

Sandblasted Surface TreatmentPurpose: Sandblasting the steel plate is a crucial surface - preparation step. The process involves propelling fine abrasive particles at high speed against the steel surface.

Removal of Contaminants: It effectively removes rust, mill scale, paint residues, and other impurities from the surface of the steel plate. This provides a clean base for further surface treatments and coatings.

Surface Roughness: Sandblasting creates a roughened surface with a specific profile. The roughness enhances the adhesion of subsequent coatings such as primers and paints. A well - adhered coating system is essential for corrosion protection, which is vital in the corrosive marine and outdoor bridge environments.

Applications in Ship and Bridge BuildingShip Building:

Hull Construction: Dh32 and Dh36 steel plates are used in the construction of ship hulls. The high strength of these steels helps in withstanding the hydrostatic pressure of water, wave impacts, and the weight of the cargo and superstructure. The sandblasted surface allows for the application of anti - corrosion coatings that protect the hull from seawater corrosion, which contains salts and other corrosive agents.

Deck and Bulkhead Installation: These steel grades are also suitable for building decks and bulkheads. The strength and toughness of the steel ensure the structural integrity of these components, which are subject to heavy loads from equipment, vehicles (in the case of vehicle - carrying ships), and crew movement. The sandblasted and properly coated surfaces prevent corrosion from water splashes and other environmental factors.
