Marine Aluminium Sunk Watertight Hatch Covers

About product

The aluminum flush-type watertight hatch cover is a critical sealing device installed on ship decks, offshore platforms, or other openings requiring watertight integrity. Its design takes into account the harsh marine environment, balancing light weight, high strength, and long-term reliability.

  • Main Material: Manufactured from high-strength marine-grade aluminum alloy, it offers excellent corrosion resistance against seawater, humid climates, and salt spray. At the same time, it significantly reduces the overall weight of the vessel, improving fuel efficiency and sailing speed.
  • Flush Design: The hatch cover is level with the deck surface, avoiding protrusions that may obstruct cargo or equipment movement. This design enhances safety and convenience for deck operations while ensuring both practicality and aesthetics.
  • Customizability: In compliance with classification society standards and customer requirements, customized solutions can be provided in various sizes, shapes, and opening methods to meet diverse engineering applications.
