Port machinery is generally used in the open air, so it is very important to perform corrosion maintenance during use.

First, during use, if the paint film is found to be damaged on the metal structure, it should be cleaned up first, and painted with anti-rust paint and decorative paint film to ensure that it will not rust in rain and snow.

The second is that for the movable parts of port machinery, the connected parts should also be anti-corrosion work. An oil film can be formed on the metal surface, which can resist temperature changes and damage.
