Galvanized steel wire is made from high-quality carbon structural steels such as 45#, 65#, and 70#. These wires undergo a drawing process and are then electro-galvanized or hot-dip galvanized to create a corrosion-resistant coating.
Post-Galvanization Drawing: This method involves quenching the wire in lead, galvanizing it, and then drawing it into the finished product. It results in a thin and uniform zinc layer and lower zinc consumption.
Process Flow: Steel wire โ lead quenching โ galvanizing โ drawing โ finished wire.
Intermediate Galvanization Drawing: Zinc coating is applied between two drawing stages, producing a thicker zinc layer than the previous method.
Process Flow: Steel wire โ lead quenching โ first drawing โ galvanizing โ second drawing โ finished wire.
Mixed Galvanization Drawing: Used for ultra-high-strength wires (up to 3921 MPa), the process combines several drawing stages with zinc coating, ensuring the zinc layer acts as both protection and lubrication.
Process Flow: Lead quenching โ first drawing โ pre-galvanizing โ second drawing โ final galvanizing โ third drawing โ finished wire.
