Product Description
5083-H116/H321 Marine Grade Aluminum Sheet & Plate for LNG Tanks | High Strength, Excellent Corrosion ResistanceHeavy-Duty, Welded Structural Aluminum Alloy Plate for Cryogenic LNG Storage, Shipbuilding & Offshore Applications. Superior Stress Corrosion Cracking Resistance. |
Product Introduction
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.
Key Features & Advantages
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.
Main Applications
Our aluminum sheets are mainly used for the fabrication of trailer tanks and related equipment, with the following specific applications:
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.

Why Choose Our Aluminum Sheets?
Our anodised aluminum sheets stand out in the market for trailer tank applications, thanks to the following core advantages:
Enhanced Corrosion Protection: The anodized layer forms a dense, hard protective film on the aluminum surface, which is 5-10 times more corrosion-resistant than ordinary mill finish sheets, effectively resisting the erosion of petroleum products and harsh weather.
Durable & Scratch-Resistant: The anodized layer has high hardness and wear resistance, preventing scratches and damages during transportation and installation, maintaining the appearance and performance of the tank for a long time.
Customizable Colors & Finishes: We offer a variety of anodizing colors (natural, bronze, black, gold, etc.) and finishes, allowing you to match the aesthetic requirements of your trailer tanks and enhance product competitiveness.
Improved Adhesion for Coating: The porous structure of the anodized layer improves the adhesion of subsequent coatings (such as powder coating), ensuring a more stable and long-lasting surface treatment effect.
Environmentally Friendly Anodizing Process: Our anodizing process adopts environmentally friendly electrolytes, no harmful substances are released, complying with international environmental standards, and the anodized layer is non-toxic and safe for food contact.
Strict Quality Control: Each anodised sheet undergoes strict inspection for anodizing thickness, uniformity, and corrosion resistance, ensuring consistent quality and meeting the high standards of trailer tank production.
Cost-Effective Solution: Although anodized sheets have a slightly higher initial cost, their long service life, low maintenance cost, and improved product value make them a cost-effective choice in the long run, helping you reduce overall project costs.
