Galvanized steel wire is made by drawing high-quality carbon structural steel such as 45 #, 65 #, 70 #, and then galvanizing (electro galvanizing or hot galvanizing).

Galvanized steel wire is a carbon steel wire galvanized on the surface by hot plating or electroplating. Its properties are the same as those 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 layer protection)
