Applications

• Offshore / Coastal High-Pressure Thread-Sealed Aluminum Covers

Threaded aluminum covers for ship storage tanks, high-pressure chemical reagent dispensing caps, sealed covers for offshore outdoor storage containers, and LNG small container end covers. Featuring high-strength thread rolling technology, they resist thread stripping and maintain long-term leak-proof performance without corrosion in seawater and high-salt storage environments.

• Marine & Offshore Engineering Aluminum Discs

Used for ship equipment end covers, marine lighting reflector bases, seawater desalination equipment liners, and small pressure-bearing discs on decks. Certified by CCS (China Classification Society), these discs offer excellent resistance to marine salt spray corrosion and wave impact.

• LNG Low-Temperature Storage Tanks & Pressure Vessel Heads

Applied in circular heads for liquid nitrogen/liquid oxygen cryogenic tanks, chemical corrosion-resistant storage tanks, and bottom plates for refrigerated transport vehicle tanks. They maintain stable mechanical properties under ultra-low-temperature conditions with excellent weldability and sealing performance.

• Heavy-Duty High-End Pressure Cookware & Kitchen Equipment

Used for commercial large-capacity pressure cookers, industrial cooking pots, and portable pressure-bearing water storage containers for vehicles. The aluminum body provides outstanding rigidity, resists denting and deformation during long-term high-temperature cooking, and delivers durable corrosion resistance in humid kitchen environments.

• Coastal Heavy-Duty Outdoor Traffic Signs & Curtain Walls

Applications include circular reflective signs for docks and offshore ports, decorative aluminum discs for offshore wind power facilities, and curtain walls for coastal industrial buildings. Designed to withstand strong winds, salt spray, and harsh marine environments without deformation or corrosion over many years.
