What are the functions of water pontoons?

The current scope of use of water pontoons is relatively wide, for example, water pontoons can be used in water docks, water platforms, yacht marinas and other aspects. The emergence of water pontoons has also made the construction of water platforms such as water docks, water platforms, and yacht marinas easier. How does such a widely used water pontoon behave in terms of performance?
Since the materials used in the water pontoon are made of materials with anti-corrosion and oxidation resistance, the water pontoon has extremely high corrosion resistance and oxidation resistance in terms of performance. In addition, the water pontoon has the ability to carry a weight of 350kg. It is precisely because of these excellent properties of water pontoons that water pontoons have been widely used in water docks, water platforms, yacht marinas and other aspects.
