Steel body cooling towers are typically made of galvanized steel, but stainless steel and aluminum are also options. All of the options are proven corrosion protection. Galvanized steel or stainless casing panels also all internal parts supports, for extra corrosion resistance are options too for structure of a cooling tower. Hot-dipped-galvanized steel is suitable from corrosion resistance point of view and also having good structural strength. Further development and improvement in the cooling tower material leads to stainless steel that is used and recommended for cooling towers installed in the highly corrosive environment. All types of cooling tower can be made of galvanized steel, stainless steel or aluminum.
