Epoxy coated strand 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. we can supply steel strands according to the customers' specific requirements in their project.
Strandard:
