Cable System Using Epoxy-Coated Prestressing Steels in China


Article Preview

Using the electrostatic spraying method to spray the epoxy coating on the surface of prestressing wire or strand. By this method, the mechanical properties can reach the same level of original prestressed steel, the anti-corrosion ability is superior to that of galvanized steel, and the epoxy coating not only does not have a negative impact on anchorage performance, but also improve the bond strength between wire and cold-cast filler. The LZM cable system using epoxy-coated wire and the OVM250 and GJ cable system using epoxy-coated strand have been developed and widely applied in China since the year of 2001.
