MC Aluminum produces a wide range of aluminum plates, extrusions, FSW panels, piping components, and aluminum-steel clad plates designed specifically for shipbuilding applications. These products feature excellent corrosion resistance, structural strength, ductility, processability, and weldability. We provide a variety of widths, thicknesses, and alloy grades, all certified by major classification societies including ABS, BV, GL, LRS, and RINA.
“ABS Marine Grade Aluminum Plate” refers to aluminum alloy plates that comply with the material requirements of the American Bureau of Shipping (ABS), and are widely used in shipbuilding and offshore structures. ABS certification ensures that the aluminum plate meets the strictest standards for chemical composition, mechanical properties, and corrosion resistance, thus guaranteeing safety and service life in marine environments.
Marine-grade aluminum plates are mainly produced from the 5000 series (aluminum-magnesium alloys) and selected 6000 series (aluminum-magnesium-silicon alloys). Typical alloys include 5083, 5086, 5052, 5454/5456, and 6061. Among them, 5-series alloys are the most widely used due to their magnesium content, providing outstanding seawater corrosion resistance and excellent weldability.

Advantages of ABS Certified Marine Aluminum Plates
1. Lightweight advantage:Compared to traditional steel, aluminum plates can reduce vessel weight by 15% to 40%, improving speed, maneuverability, stability, and fuel efficiency.
2. Superior corrosion resistance:Outstanding resistance to seawater, especially with 5083 and 5086, commonly known as "anti-rust aluminum plates."
3. Excellent weldability:Ensures high reliability in the extensive welding processes required in ship construction.
4. Good formability:Supports a wide range of ship designs, from small yachts to large cruise ships.
5. Sustainability:Highly recyclable, in line with the shipping industry's green development trend.
6. Low-temperature toughness:Retains good toughness in cold waters, suitable for polar or low-temperature navigation.
Typical Applications
1. Hull Plating
Large bulk carriers, ferries, and offshore workboats often use 5083-H116 / H321 plates with thicknesses of 6-30 mm. Aluminum reduces overall ship weight by 15-20%, lowering fuel consumption and increasing endurance.
2. Superstructures
Yachts and passenger ship superstructures commonly adopt 5052, 5083 aluminum plates. Their light weight lowers the center of gravity, improving stability. They also offer excellent surface finish for anodizing or coating.
3. Decks and Bulkheads
Checker plates (5052, 5754) are widely used as anti-slip decks due to their durability and aesthetics. Bulkheads are typically made from 5083-H321 to meet strength and impact resistance requirements.
4. Offshore Platforms
ABS certified aluminum plates are used for offshore wind power platforms, drilling rigs, passageways, and equipment foundations, especially in environments exposed to salt spray and waves.
Dimensions of Marine Aluminum Plates
Thin plates: 0.2-6.0 mm
Thick plates: 6.0-260 mm
Width: 800-4300 mm
Length: 1000-38,000 mm
Coil thickness: 0.2-12 mm
Can be customized according to customer needs.
How is the Price of ABS Marine Aluminum Plate Calculated?
Marine aluminum plate prices are usually composed of the daily aluminum ingot price plus processing costs. Since the ingot price fluctuates daily, quotations may vary accordingly.
