·Prevent infiltration of rain water into the cable Compared to the conventional round shape steel wire wrapping system, impermeability of S-shaped wire wrapping against water is significantly improved.

·Prevent cracks in the paint coating layers A wrapping method with wire having an S-shaped section (S-shaped wire wrapping) restricts displacement of wire laps during the process of tensioning and contracting of main cable and paint cracks occur with difficulty thanks to the structure where laps of the wire are engaged with each other.

·Reduce materials consumption of external coating Because the surface of S shape wrapping wire is flat compared with the round steel wire, which can effectively reduce filling materials consumption of external coating.
