MC Aluminum provides a wide range of extruded aluminum profiles suitable for various shipbuilding applications-from commercial vessels, naval ships, to large barges and floating platforms. Aluminum is easy to process into different shapes and sizes, making it a highly versatile material for marine use. In addition to extruded profiles, we also supply DNV-certified aluminum plates and sheets for marine applications.
The marine aluminum profiles produced by MC Aluminum are commonly made from 6082, 6061, 6063, 5083, and 5052 alloys. Our products are certified by CCS, DNV, NK, ABS, BV, LR, KR, and other classification societies, meeting diverse shipbuilding requirements.

Why Aluminum Extrusions are Ideal for Shipbuilding
1. Excellent Corrosion Resistance
Marine-grade aluminum alloys form a stable oxide film enriched with magnesium, effectively resisting seawater, salt spray, and humid environments.
2. Significant Weight Reduction
Aluminum’s density is only one-third that of steel. Using aluminum profiles greatly reduces vessel displacement and improves fuel efficiency.
3. High Strength and Toughness
With optimized alloy composition and heat treatment, extrusions combine excellent toughness with sufficient strength for ship structures.
4. Superior Workability
Aluminum extrusions can be processed through welding, bending, and forming, making it easier to create complex structures, increase efficiency, and simplify construction.
5. Sustainability & Recycling
Aluminum is 100% recyclable, and remelting requires only about 5% of the energy needed to produce primary aluminum.
6. Non-Magnetic
Marine aluminum reduces magnetic signatures, helping to avoid triggering magnetic mines or interfering with sensitive equipment.
7. Aesthetic and Durable
Surface finishes such as anodizing, painting, and polishing not only provide lasting protection but also deliver attractive appearance, ideal for yachts and passenger vessels.
Applications of Marine Aluminum Extrusions
Shipbuilding: Hull structures, decks, bulkheads, masts, railings, window frames, ladders-used in yachts, fishing boats, cruise ships, and naval vessels.
Offshore Platforms: Walkways, railings, stairs, deck structures, and support frames for offshore oil rigs and wind power platforms.
Port Facilities: Wharf bridges, guardrails, crane beams, and structural parts for container gantry cranes.
