The watertight hatch cover is an important outfitting device. It is used to cover the hatch and protect the cargo in the cabin from wind, waves and rain. When the ship is loading and unloading cargo, it can be easily opened and closed, and the cargo hatch cover should have sufficient strength to ensure that it will not deform under specified wind waves or other set loads and affect its use. Watertight hatch covers can be made of aluminum and steel.
