Switch to a metal that will not corrode when exposed to water.Coat the steel with a physical barrier to prevent water from reacting with the iron.
2.Galvalume Steel Sheet = Aluminum Zinc Steel Sheet= PPGL
Galvalume has barrier corrosion resistance and heat resistance similar to aluminized material and good bare edge
galvanicprotection and forming qualities like galvanized material. Consequently, Galvalume and Galvalume Plus will resist rust
