In order to prevent the rust of the stud link anchor chain, the asphalt coating method is mainly used. Generally, it is necessary to apply 2­­­3 channels, and the dust on the surface of the anchor chain should be cleaned before coating. The thickness of the dry film of the asphalt coating should be more than 60μm. When the protective layer is peeled off, it should be repaired in time to prevent it. The anchor chain is further rusted.
