Shipping container pools can rust if they are not properly coated or maintained. Shipping containers are typically made of steel, which is prone to rusting when exposed to moisture and oxygen. However, shipping container pools can be coated with a protective layer of paint or other materials to prevent rust. It's important to note that regular maintenance, such as keeping the pool clean and free of debris, can also help prevent rusting. Additionally, proper installation of the pool and a good drainage system can help prevent water from accumulating around the container and causing rust.
