Applications
These tough, reliable coating layers offer high corrosion resistance and reduce maintenance expenses by eliminating the need for protecting and maintaining structures easily to be corroded. And epoxy coated strand is mainly used in the following fields:
External cables.
PC marine structures.
PC structures subject to salt damage.
Heavy duty corrosion resistant anchors.
Materials subject to long-term exposure.
Tension materials on stay cable bridge.
Epoxy coated strand is a new product developed from common PC strand. The surface of the common PC strand commonly dose not have any coating layer. While the epoxy coated strand& acute;s surface has a layer of epoxy resin which will combine with the steel during stressing without cracking or losing adhesion. In the coating process, it will not pollute the surrounding environment and the wire tensile strength is without losing. At the same time, the coating layer is able to resist physical wearing and chemical corrosion. Now, the technology of coating type and filling type has already been matured.
