About product
Marine aluminum manhole cover is a commonly used key sealing device in ship cabins, manufactured from high-strength aluminum alloy. It is mainly applied for sealing inspection openings on decks or bulkheads, featuring advantages such as lightweight design, corrosion resistance, and easy operation. Compared with traditional steel manhole covers, aluminum products significantly reduce overall weight while ensuring strength and sealing performance, thereby improving vessel speed and fuel efficiency.
- Reliable watertightness: Tested under ≥2 kg/cm² water pressure to ensure sealing performance even in harsh sea conditions.
- Flexible installation: Available in round, elongated, or oval shapes customized according to deck, bulkhead, and installation space requirements.
- Easy maintenance: Lightweight and easy to assemble/disassemble, with rubber gaskets that can be quickly replaced.
- Adequate strength: While reducing weight, it still provides sufficient strength to meet inspection and pressure-bearing requirements.
