About product
Aluminium watertight hatch covers are used on exposed ship decks, storage hatches, inspection openings, and other areas that require reliable watertightness, making them an essential sealing device on board. Manufactured entirely from high-strength aluminium alloy, they feature lightweight construction, high strength, and excellent corrosion resistance. These advantages significantly reduce the vessel’s overall weight, improve speed and fuel efficiency, and make them especially suitable for high-speed craft, passenger ships, and yachts where weight reduction is critical.
- The density of aluminium alloy is only one-third that of steel, which ensures sufficient load-bearing strength while reducing the structural weight of the vessel.
- In addition, aluminium alloy naturally provides excellent seawater corrosion resistance, allowing for long-term use without the need for additional coatings and lowering maintenance costs.
