5083-H116/H321 Marine Grade Aluminum Sheet & Plate for LNG Tanks | High Strength, Excellent Corrosion Resistance
Heavy-Duty, Welded Structural Aluminum Alloy Plate for Cryogenic LNG Storage, Shipbuilding & Offshore Applications. Superior Stress Corrosion Cracking Resistance. |
Our 5083 marine-grade aluminum sheet and plate, supplied in the H116 or H321 temper, is the premier choice for high-strength structural applications in harsh marine and cryogenic environments. Specifically designed for welded constructions, it offers exceptional resistance to seawater corrosion and stress corrosion cracking (SCC).
With outstanding toughness and mechanical properties retained at temperatures as low as -196°C, it is the industry-standard material for Liquefied Natural Gas (LNG) cargo and fuel tank membranes, hulls, superstructures, and offshore platforms. This alloy provides an ideal combination of light weight, formidable strength, and long-term durability, reducing lifecycle costs for critical marine and energy infrastructure projects.
Exceptional Marine Corrosion Resistance: Offers superior resistance to saltwater, brines, and industrial chemicals, minimizing maintenance in offshore and coastal environments.
Superior Welding Performance: Excellent weldability with common methods (MIG, TIG, FSW), maintaining high joint efficiency and corrosion resistance in the weld zone.
High Strength & Lightweight: Achieves high strength-to-weight ratio, enabling significant weight savings in marine vessels and structures for better fuel efficiency and payload.
Outstanding Cryogenic Toughness: Retains excellent ductility, impact strength, and fracture toughness at extremely low temperatures, making it perfect for LNG containment systems.
Good Fatigue & Stress Corrosion Cracking (SCC) Resistance: H116/H321 tempers provide enhanced stability and resistance to SCC, crucial for long-term structural integrity under stress.
LNG Industry: Inner walls of LNG carrier tanks, linings for onshore LNG storage tanks, LNG fuel bunkers, piping, and components.
Shipbuilding & Marine: Ship superstructures, bulkheads, decks, piping systems, gangways, marine furniture.
Offshore Engineering: Living quarters on offshore platforms, helicopter decks, cable trays, corrosion-resistant containers.
Transportation: Truck bodies, tanker trucks, refrigerated van panels.
Other Industries: Anti-corrosion equipment for chemical processing, food processing equipment, architectural cladding.

Robust Packaging Solutions for Safe Global Delivery
To ensure the integrity of our Aluminum Plate Alloy 7075 T6/T651 during transit, we employ industry-leading packaging methods tailored to your needs:
| Packaging Feature | Description |
|---|---|
| Standard Packaging | - Material: Moisture-proof plastic film + anti-rust paper wrapping. - Protection: Edges covered with protective PVC/plastic caps. - Bundling: Steel straps or heavy-duty nylon belts for secure bundling. - Palletizing: Stacked on wooden pallets (ISPM 15 compliant) for forklift handling. |
| Customized Options | - Vacuum-sealed packaging (for high humidity regions). - Foam/PE foam interlayers for scratch prevention. - Reinforced wooden crates (for oversized plates or fragile surfaces). |
| Quality Assurance | - Pre-shipment inspection to confirm no surface damage or deformation. - Humidity indicator cards included (optional). |
| Labeling & Documentation | - Clear labels with product specs, LOT number, and gross/net weight. - Customized branding or shipping marks available. - Complete documents: COC, MSDS, and Mill Test Reports. |
| Environmental Compliance | - Recyclable materials used (wood, paper, non-toxic films). - Compliant with international hazardous material regulations. |
Key Advantages:
Damage Prevention: Multi-layer protection against moisture, scratches, and impact.
Custom Flexibility: Adapt packaging to sea/air/land freight requirements.
Cost-Effective: Optimized packaging reduces shipping volume and costs.
Storage Recommendations:
Store in a dry, ventilated warehouse; avoid direct sunlight or corrosive environments.
Keep plates flat or vertically supported to prevent warping.
