Technical Specification hull door
Stern Platform Doors and the frames can be manufactured out of shipbuilding steel Grade A, stainless steel 316L or seawater resistance aluminium 5083. The Stern Platform Door is a welded construction out of CNC laser and water cutted plates and stiffeners. The Stern Platform Door is cutted out with high quality Newthex Parts. Hinges and latches are of stainless steel 316L. When closed the Stern Platform Door will be flush with the stern. Water tightness is achieved by a rubber seal or a vacuum rubber seal. Just for reasons of safety, no inflatable seals will be applied.
