How to Rust-Proof Facade Ironwork?

Most facade iron components are made of metal, and when deeply buried underground, they can rust due to external environmental factors, leading to issues like exposed coatings. This problem has also troubled many construction workers. The rust on facade iron components is not due to inherent damage but rather due to breakage at the connection points, which can lead to hidden dangers. Therefore, rust issues have received attention from relevant inspection departments. As a result, properly removing rust from facade iron components is crucial.
