Aluminum for Boat Building
Aluminum alloys for marine use can be classified into various product types, including marine grade aluminum sheets, aluminum profiles, aluminum tubing, aluminum rods, forgings, castings, and more.
Hull structure of ship
The aluminum alloys primarily used for the hull structure of ships are 5083 aluminum, 5086 aluminum, and 5456 aluminum.
Superstructure of Ship
The 6000 series alloys are mainly used for the superstructure of ships because they are prone to intergranular corrosion in seawater.
Outfitting Aluminum
The ship outfitting primarily utilizes extruded aluminum profiles for upper ship structures, such as extruded structures and deck.
Our Aluminum Plate Hickness
The thickness of marine grade aluminum sheet used is determined by factors such as ship structure, vessel specifications, and application areas. Thinner plates are generally preferred for lightweight considerations, but the depth of corrosion during the service life of the plates should also be taken into account. Commonly provided aluminum plate thicknesses include thin plates of 1.6mm and thicker plates of 30mm and above.
Our Aluminum Plate Size
To minimize welding, 2.0m-wide aluminum plates are commonly used, while large vessels employ 2.5m-wide plates. These aluminum plates typically have a length of 6m, and we also provide special dimensions as per shipyard contracts. Patterned plates are used on the decks for slip resistance.
