Mafo watertight doors

  • Standard clear openings from 500 x 1250mm
  • Standard pressure classes up to 150 kPa.
  • Suitable for inside walls and outside walls.
  • Designed with an L frame as a standard. T frames are used for outside walls that need an extreme and non-standard low RCS.
  • The door frames can be designed to contribute to the structural strength of the ship walls.
  • Doors can be built in vertical walls with an inclination up to 11 degrees without special facilities. In case of larger inclination angles are required, facilities can be built-in in order to keep the operation forces as low as possible.
  • Operation forces generally comply with the most common ergonomic requirements.
  • Doors can be designed with all typical accessories, such as windows, locks, overpressure safety devices, hold-open devices, switches and test plugs.
  • Mafo also builds double doors with or without regular door.
  • Besides standard designs, custom built solutions are also possible.
  • Special doors, such as for the installation with bolts, elevator doors and extra strengthened door sheets for the protection against ammunition and splinter impact can also be delivered by us.
