Ship Aluminium Watertight Door

Category

About product

Marine Aluminium Watertight Doors are essential safety equipment in modern vessels and offshore engineering facilities, primarily used for compartment separation and watertight protection. These doors not only provide reliable watertight performance but also feature lightweight construction, corrosion resistance, and easy maintenance, making them highly suitable for ships requiring weight reduction and improved fuel efficiency.

  • Lightweight Design: The door panels are constructed with an aluminium honeycomb core, achieving approximately 40% weight reduction compared with traditional steel watertight doors. This significantly lowers weight while maintaining the same compressive and impact strength, enhancing the vessel’s overall efficiency and stability.
  • Excellent Corrosion Resistance: The door surface is treated with anodizing or fluorocarbon coating, providing salt spray resistance of more than 3000 hours. This ensures outstanding durability in high-salinity and high-humidity marine environments, extending service life.
  • Optimized Key Components: Hinges, locks, and fasteners are made of 316L stainless steel, effectively preventing galvanic corrosion between aluminium and steel, ensuring long-term reliability.

Product Detail

Ship Aluminium Watertight Doors

Marine aluminium watertight doors are widely used on high-performance passenger ships, yachts, drilling platforms, and offshore support vessels. They are particularly suitable for areas where lightweight construction and corrosion resistance are critical, such as superstructures, accommodation entrances, engine rooms, and deck passageways.

  • Watertight Performance: Equipped with high-performance sealing gaskets and quick-closing mechanisms, the doors ensure excellent watertight integrity even in cases of compartment flooding or harsh sea conditions.

  • User-Friendly Design: Optional features include observation windows, ventilation grilles, and escape hatches, providing enhanced ventilation, visibility, and emergency evacuation capabilities for different compartments.

  • Easy Operation: The quick-closing design allows for single-person operation, improving response efficiency in emergency situations.

Fast Open/Close Aluminium Watertight Door

Our quick-opening aluminium watertight door is specifically designed for lightweight, high-performance vessels such as aluminium ships, speedboats, and marine patrol boats. It is primarily installed at exterior entrances of superstructures to ensure compartment safety and watertight integrity. In terms of watertight performance, the door utilizes high-performance sealing gaskets combined with a compression mechanism, allowing it to withstand water pressure up to 0.03 MPa. This ensures reliable sealing even under extreme conditions such as heavy rain, wave impact, or compartment flooding, effectively preventing seawater ingress and enhancing the overall safety and reliability of the vessel.

Additionally, our ship aluminum door is equipped with a quick-opening mechanism that supports single-person rapid operation, improving convenience during daily use and significantly enhancing emergency response efficiency. Depending on application requirements, the door can also be fitted with observation windows, ventilation grilles, or escape hatches, meeting diverse needs for ventilation, monitoring, and safe evacuation.
