Shipbuilding is a complex and delicate process that requires the use of a variety of materials and techniques. There are mainly the following materials:

Steel: In modern shipbuilding, steel is one of the most commonly used materials. It has high strength, high toughness and corrosion resistance. Commonly used steel includes hull structural steel, deck steel, mechanical steel, etc. In addition, there is low-alloy high-strength steel (LNG) used in the manufacture of large ships.

Aluminum: Aluminum is a lightweight, corrosion-resistant material and is therefore gaining popularity in modern boatbuilding. It is often used in the manufacture of ship shells, decks, equipment brackets, etc. In addition, there are some high-strength aluminum alloys that can be used to manufacture special-purpose ship components.

Copper: Copper is rarely used in ships, but it has important applications in some key parts. For example, copper pipes in marine piping systems can withstand high pressure and high temperature because of copper's good thermal conductivity and corrosion resistance.

FRP: Fiberglass reinforced plastic (FRP) is a lightweight, high-strength composite material widely used in internal components, decks, pipes and equipment supports of ships. Commonly used FRP materials include GRP sheets, pipes and profiles.

Ceramics: Ceramics may be used for wear-resistant or heat-resistant coatings on ships in some special cases. Commonly used ceramic materials include alumina ceramics, silicon carbide ceramics, and the like.

Rubber: Rubber is mainly used in the manufacture of seals, gaskets and pipe connections in ships. Commonly used rubber materials include nitrile rubber, neoprene rubber, polyurethane rubber, etc.

Regarding classification society information, the International Organization of Classification Societies (IACS) is an international organization responsible for developing and issuing various ship class certifications. At present, there are many classification societies recognized by IACS, such as the United States Coast Guard, the Norwegian Maritime Administration, and the Royal Naval Academy. These classification societies evaluate and certify the design, construction and operation of ships to ensure that requirements such as safety and environmental protection of ships are met.
