-Made from high carbon steel rods. Wires with diameter above 1.0 mm are cold drawn and then phosphated, wires below 1.0 mm require heat treatment.
-The phosphated surface provides excellent lubrication and rust resistance, serving as strength support elements in optical cables.
-Annual capacity of 30,000 tons, meeting different customer needs.

-Phosphated steel wire for optical cables requires very high elastic modulus and tensile strength;
-High dimensional accuracy and good straightness;
-Dense and uniform phosphating film on the surface;
-The phosphating film chemically stabilizes the wire surface, preventing chemical reactions with cable grease, effectively avoiding hydrogen-induced damage.
-Used as strength support components in optical cables.
