The products shold be slightly twist with the high strength galvanized steel or galvanized - aluminum alloy steel, hot extruded high density polyethylene, and arranged the socket at both ends, act as the cable-stayed bridge cable, the hanger, the tie down cable and special structure cable.

Because the cable has large flexibility, small resistance and light weight, the vibration of cable is very easy to occur, especially under the combined action of wind and rain.

Making regular pattern or spiral lines on the surface of a smooth cable, which effectively damage the formation of waterway on the cable surface, at the same time, the drag coefficient of cables is no more than 0.8. Finally, the wind and rain vibration of cables can be effectively suppressed.

The technology of wind-rain vibration suppression has been successfully applied to Sutong Yangtze River Bridge, Hongkong Stonecutters Bridge, Korea Inchon Bridge, Hangzhou Bay Bridge, Hong Kong Zhuhai Macao Bridge, Quanzhou Bay Bridge, Xiangshan Harbour Bridge and Hundreds of domestic and oversea large projects. Currently these cables of wind-rain vibration suppression is in good condition.
