Why New Caledonia Projects Need Marine-Grade Aluminum
New Caledonia has a tropical marine climate. Coastal humidity, heavy rainfall, and salt spray in the air accelerate the corrosion of standard metals. For coastal engineering and structural installations, materials must resist galvanic corrosion and saltwater oxidation while maintaining steady mechanical strength over time.
For this project, the buyer needed a balance of high seawater corrosion resistance for plate surfaces and reliable structural strength for supporting frames. Combining 5000-series marine plates with 6000-series extruded profiles provided an efficient, long-lasting solution without inflating the material budget.
Aluminum Alloy Breakdown and Applications
5083-H116 Aluminum Plate (3 mm – 10 mm)
5083-H116 is an aluminum-magnesium alloy designed specifically for marine environments. The H116 temper ensures the material does not suffer from intergranular corrosion or exfoliation when exposed to seawater.
Common Everyday Uses:
- Hulls, decks, and bench seating for coastal workboats and fishing vessels.
- Bottom plates and baffles for diesel or water storage tanks.
- Flooring and walkways in coastal processing plants.
6061 Aluminum Channel
6061 is a structural alloy known for its strength-to-weight ratio and ease of machining. It handles standard welding and bolting well, making it the industry standard for load-bearing frameworks.
Common Everyday Uses:
- Support frames for industrial storage shelves and warehouses.
- Chassis runners and structural cross-members for utility trailers.
- Mounting structures for solar panel arrays in high-wind areas.
6063-T5 Aluminum Angle Bar
6063-T5 offers excellent extrudability, giving it clean, sharp edges and a very smooth surface finish. While slightly less rigid than 6061, it resists atmospheric corrosion well and is widely used where clean fitment is required.
Common Everyday Uses:
- Corner protection and framing for equipment enclosures.
- Architectural edging, window frames, and door trims.
- Lightweight mounting brackets for electrical cabinets.
Need a Mixed-Load Aluminum Shipment?
Consolidating different alloys, plates, and extruded profiles from multiple suppliers can cause shipping delays and higher freight costs. GNEE supplies multi-specification aluminum orders in a single container.

Quality Inspection and EN 10204 3.1 Certification
Before shipment, our quality control team performed strict inspections on the entire 11.84-ton batch:
- Chemical Composition Analysis: Checked via optical emission spectrometer to verify magnesium (Mg) levels in the 5083 plates and silicon-magnesium (Si-Mg) balance in the 6061/6063 profiles.
- Mechanical Property Testing: Tensile strength, yield strength, and elongation were tested to confirm compliance with ASTM B209 and ASTM B221 standards.
- Dimensional and Flatness Inspection: Micrometers and ultrasonic thickness gauges were used to ensure the 3mm–10mm plates met thickness tolerances without edge waving.
- Surface Inspection: 100% visual inspection to verify there were no oil stains, scratches, or handling marks.
- Every shipment is delivered with an EN 10204 3.1 Mill Test Certificate (MTC), giving our clients verifiable test data directly from the quality laboratory.

Export Packaging for Sea Freight
Aluminum is vulnerable to "white rust" (aluminum oxide) if moisture or salt water gets trapped between plates during sea freight across different climate zones. Since this shipment traveled through tropical ocean routes to New Caledonia, we applied enhanced seaworthy packaging:
- Moisture Protection: Plates and profiles were wrapped in waterproof kraft paper and sealed inside tight-layer plastic films.
- Desiccant Packs: Industrial silica gel packets were placed inside the wrapping to absorb condensation during ocean transit.
- Wooden Palletization: All materials were secured on fumigated wooden pallets compliant with ISPM 15 export standards.
- Edge Reinforcement: Steel banding with edge guards was used to prevent straps from biting into the aluminum edges during forklift handling and crane loading.
Shipping and Delivery Timeline
The total volume was optimized to fit securely into a standard 20-foot dry container (20FT FCL) to minimize freight costs per ton.
