Generally, the purchase of marine grade alloy plates requires classification society certification, that are CSS and DNV. Haomei Aluminum is a rare company in China that is certified by classification society aluminum plates. Haomei aluminum marine grade aluminum plates have passed the certification of CCS China Classification Society and DNV Det Norske Veritas. The marine grade aluminum alloy products are mostly used on the deck of ships, small yachts and fishing boats. 5083 aluminum plates are used for marine aluminum plates in the state of 5083H116/H321/H112/H321 aluminum plates.

The 5083 marine aluminum plate and 5086 aluminum plate produced by Haomeii Aluminum has obtained the Norwegian ship classification certification. The marine grade alloy plate produced by Haomei Aluminum is in the state of H116/H321/H112. The 5083 and 5086 marine grade aluminum alloy have superior anti-corrosion and rust resistance. The 5083 and 5086 aluminum plate belong to the Al-Mg series alloy, they have a wide range, especially the construction industry cannot do without this alloy, it is a promising alloy. The 5083 alloy aluminum plate has good corrosion resistance, excellent weldability, good cold workability and medium strength.

Generally speaking, the thickness of the marine grade alloy plate is determined by the hull structure, ship specifications and use parts. From the perspective of hull weight reduction, thin plates are generally used as much as possible, but the depth of corrosion of the plates during use should also be considered. The plates used are thin plates over 1.6mm and thick plates over 30mm. Some special specifications are also used in accordance with the shipyard contract. For non-slip, the deck adopts 5083 aluminum checker plate.
