The steel structure
        
To the steel structure, the speed of corrosion is mainly relate to the air relative humidity and the
        
composition and quantity of pollutant in the atmosphere.
        
In order to reduce metal corrosion and extend its service life, we must adopt the spreads brushes
        
and spray finishing methods after operate the surface treatment, to form the protective film in the
        
metal surface, and cause the metal and the corrosive medium isolates, thus prevents the metal the
        
corrosion.
