As an important part of bridge, Steel Strand plays a major role for the safe use of bridge.Some countries began to use steel strand since 1980’s, in addition to the selection and production quality of steel material, an special high molecular synthetic material is required to be used as anticorrosion and waterproof protection on the surface. Some common materials are low efficient and potentially risky. SWD Company developed Polyurea protective coating specifically for Steel Strand of Cable-stayed Bridge which was widely used in America and Europe.Earlier 2012 SWD began to produce this coating in Shanghai, and exported to Europe, this product has been used by Anhui Province Transportation Group after many times of test with good performance.
The product has high reactivity, could spray-applied forming oncurved,slope and vertical surface without sagging. Dense andseamless coating fully isolates all kinds of corrosive agents. High adhesion to steel strand with good performance of flexibility, wear resistance and impact resistance, anti-aging, anticorrosive,water proof.
