As a company specializing in the export of marine aluminum materials, Haomei Aluminum adheres to international shipbuilding standards and leverages the authoritative certification of DNV (Det Norske Veritas) to create marine-grade aluminum sheets suitable for global marine environments. Our products are sold to over 60 countries and regions, providing in-depth services to major shipyards and marine engineering equipment companies both domestically and internationally, making us a trusted aluminum material partner in the global shipbuilding industry.

Haomei DNV certified marine grade aluminum sheets are based on proprietary marine alloy formulas, forming a complete product matrix with the 5000 series (5083/5086/5052) as the main type and the 6000 series (6061) as a supplement. Among them, 5083-H116/H321 serves as the main grade for ship structures, becoming an internationally recognized preferred alloy for marine applications due to its excellent comprehensive performance. 5086 focuses on enhanced corrosion resistance, while 6061 balances high strength and ease of processing, precisely matching the differentiated needs of various ship components.

Leveraging a superior alloy system, our DNV-certified marine grade aluminum sheets possess multiple core characteristics:

- Superior seawater corrosion resistance:

The magnesium-manganese alloy forms a dense oxide film, effectively resisting high-salt spray and chloride ion corrosion, maintaining stable performance even in extreme ocean environments, significantly reducing later maintenance costs.

- Lightweight and high-strength:

With a density only 1/3 that of steel, it achieves lightweight hull upgrades. Tensile strength reaches 290-350MPa, ensuring structural safety and impact resistance while reducing hull weight, improving load capacity and fuel efficiency.

- Excellent welding and forming:

Supports MIG/TIG full-process welding, with weld strength exceeding 90% of the base material. Welds are crack-free and deformation-free, adaptable to complex hull surfaces and structural component machining.

- DNV global approval:

Certified by Det Norske Veritas (DNV), it complies with international shipbuilding standards and can be directly used in the construction of various types of ships worldwide and for classification society inspections, requiring no additional testing or adaptation.

For marine grade aluminum sheets, quality is the foundation and the core competitiveness of Haomei Aluminum. We have built a rigorous quality control system throughout the entire process to export-grade standards, ensuring product quality from the source.

- Precision rolling process:

Utilizing imported complete sets of equipment, thickness tolerance is controlled within ±0.05mm, resulting in a smooth, clean surface free of oxidation defects, meeting the high-precision assembly requirements of ships.

- Comprehensive performance testing:

Each batch undergoes triple verification of mechanical properties, salt spray corrosion, and weldability, achieving 100% compliance with DNV certification standards. Substandard products will never enter the market.

- Sea freight protection:

Dedicated export packaging, moisture-proof and scratch-resistant, suitable for long-distance sea freight and overseas warehousing, ready for immediate use upon arrival.

- Full-chain traceability:

Each marine grade aluminum sheet comes with a DNV certification number and production record, ensuring traceable quality and worry-free after-sales service. This full-chain quality traceability gives customers at home and abroad peace of mind.

With its stable quality and diverse performance characteristics, our DNV-certified aluminum sheets are widely used in all types of vessels, including ocean-going freighters, container ships, yachts, fishing boats, and workboats, covering core components such as hull structure, decks, bulkheads, and superstructure. They are also suitable for marine engineering structural components such as offshore platforms and offshore wind power equipment, meeting the design, construction, and certification needs of shipyards worldwide.

Haomei Aluminum consistently adheres to DNV certification as its quality baseline and export standards as its benchmark. Through stable performance, stringent quality control, and professional services, we provide reliable aluminum material support for the lightweighting and safety upgrades of ships worldwide, becoming your long-term trusted partner for marine grade aluminum sheets.
