Galvanized steel wire is made by drawing 45 #, 65 #, 70 # and other high-quality carbon structural steel, and then galvanizing (galvanization or hot galvanizing).
Galvanized steel wire is a carbon steel wire that is galvanized on the surface by hot plating or electroplating. Its performance is the same as that of straightened and tempered steel wire. It can be used as unbonded prestressed reinforcement, but at least 200~300g zinc shall be plated per square meter. It is often used as parallel steel wire cable of cable-stayed bridge (in addition, flexible cable sleeve is also used as outer protection).
