Overview
The hatch cover is made of aluminium alloy and has excellent corrosion resistance and strength to last long in the Marine environment. It is designed as a sunken square, which is not only beautiful and generous, but also can better fit with the hull to ensure sealing performance.
The hatch cover has good water tightness, which can effectively prevent seawater from entering the cabin and ensure the safety and stability of the ship. At the same time, its strong structure can also withstand a certain amount of pressure and impact, providing reliable protection for the ship.
In addition to square hatch covers, we also offer two types of oval/round sink covers.
