Marine Aluminum Plate Description
DNV/ABS Certified Marine Grade Aluminum Plate
As a leading global manufacturer, GNEE specializes in providing high-performance marine-grade aluminum plates designed to withstand the most corrosive saltwater environments. Our aluminum alloys, certified by DNV, ABS, BV, CCS, KR, LR, NK, and RINA, are engineered for structural integrity, superior weldability, and long-term durability in the global shipbuilding and offshore industry.
In the field of shipbuilding, aluminum plates, as a lightweight and high-strength material, are widely used in hull structures, decks, bulkheads, and other parts. Marine ship plates generally use 5-series and 6-series aluminum alloy materials with high corrosion resistance, such as 5083 aluminum plates, 6061 aluminum plates, etc.
The common states of marine aluminum plates are H116 and H321, and the aluminum plates in these two states have good mechanical properties and corrosion resistance. At the same time, the thickness of marine aluminum plates is generally between 3 mm and 40mm, which can be selected according to specific needs.
5000 Series Aluminum Sheets are typically an aluminum-magnesium alloy with small amounts of other trace elements. They can be used in a variety of wet and corrosive locations due to their excellent rust and corrosion resistance.
6000 series aluminum alloy plate, with its light weight, high strength, high stiffness, and high corrosion resistance, is highly processable and suitable for the manufacture of complex-shaped hulls. Its strong welding performance makes it easier to assemble and connect various parts of the ship.

Our advantages
Advanced Manufacturing: The GNEE Difference
1. Stress-Relief Technology (3000T Stretching)
Most aluminum plates warp after being cut. At GNEE, we utilize a 3000T stretching machine to apply 1.0% to 3.0% permanent plastic deformation. This process "locks" the molecules in place, ensuring that when you cut our plate, it stays as flat as a mirror.
2. Marine-Grade Surface Protection
Every plate is inspected for surface defects. We offer Blue PVC Film or paper interleaving to protect the mill finish from scratches during transit and fabrication.
3. Global Logistics & Seaworthy Packaging
GNEE understands the rigors of international shipping. Our export packaging includes:
Multi-layer moisture-proof brown paper.
Heavy-duty reinforced wooden pallets
Standard 20GP/40HC container loading (18-24 tons per container).
Expert Guidance for Marine Interior Materials
While 5000 and 6000 series are used for structural components, GNEE's 3003 and 3004 Aluminum Sheets are ideal for non-structural marine applications.
3003/3004 Series: Best for color-coated interior panels, honeycomb cores, and cabin furniture, providing a lightweight and fire-resistant alternative to steel.
