Two of the supplier's Made-in-China listings document the marine programme. The marine aluminium alloy plate listing (5052/5083/6061) publishes hot rolled plate at 6–300 mm thick, 500–2700 mm wide and 1000–10000 mm long, including the full 5xxx marine family — 5052, 5A02, 5A03, 5A05, 5251, 5181, 5083, 5086 — in tempers F, O, H111 and H112 alongside T-tempers for the 6xxx/7xxx/2xxx entries. The marine grade plate listing narrows the same programme to 5052, 5083 and 5754, the three grades boat builders specify most.

A note on certification: this site does not present the plate as class-approved — no classification-society certification is claimed for it here. The company's management system certification is listed on Made-in-China as ISO 9001, and certificates are available upon request. If your build requires class-certified plate, state the society and rule set in the enquiry so the answer — whichever way it goes — is in writing before you commit.
For grade-level decisions, the dedicated pages go deeper: 5083 plate for the main hull grade, 5052 for the lighter fabrication grade that spans sheet and plate, and 5454 where the same alloy family is used for tanker work. Plate is quoted per alloy, temper and cut size.
Specifying marine plate
Marine plate enquiries in this catalogue are built from the two listings quoted above, and they work best as a cut list: grade (5052, 5083 or 5754 for the marine grade programme), temper (H111 and H112 are the published marine tempers for the strain-hardened grades), thickness, and piece sizes. Welding is the other fact to state — most marine plate is bought for welded fabrication, and the 5xxx family in these listings is the weldable magnesium-alloy family; if your yard runs a specific filler or procedure, naming it in the enquiry lets the reply confirm the grade choice against it.
Buyers comparing this programme with the wider plate range: the marine listings above carry the marine dimensions; the full hot rolled programme, including mould and thick plate, is the general plate range; and 5083 — the single most specified marine grade — carries fuller grade data, including the minimum order history published for that grade. Quote each requirement against the listing that publishes its figures.
Availability across the published dimension range is size-dependent — the extreme thicknesses and widths of the marine listing are produced against orders rather than held as shelf stock in every temper. The quotation stage confirms the size and temper combination you need, so treat the published range as the production envelope and your cut list as the specification to be confirmed.
Is 5083 the only marine grade you list?
No — the marine grade listing covers 5052, 5083 and 5754, and the wider marine alloy listing adds 5A02, 5A03, 5A05, 5251, 5181 and 5086.
Can marine plate be supplied as stretched plate?
A stretched plate variant is published on the marine alloy listing at 6–70 mm thick and 2000–10000 mm long.
Is the plate classification-society certified?
This site does not claim class certification for the plate. State your certification requirement in the enquiry and get the position in writing.
