Rail Fastening System Products

Rail fastening systems are connectors between the rails and railroad sleepers. They are essential to the fixing of the rails to railroad sleepers to provide strong and flexible connection between rail and its supporting structure. It is a fundamental component in ensuring the safe and efficient operation of each railway track. In addition, rail fastening systems play a critical role in reducing the vertical, lateral and longitudinal sliding of rail from the forces generated from a moving railway car. Rail fastening systems minimize such movements in order to ensure the smooth operation of rail tracks.

According to the Frost & Sullivan, we have consistently been one of the leading rail fastening system providers in the PRC in terms of revenue since 2012.

We supply our products to all segments of the railway transportation industry, ranging from high speed railway and heavy haul railway series to traditional track series and metro series. Moreover, our rail fastening system products have been widely applied in the PRC railway network, including railways in plateaus, frigid and high-temperature areas, heavy-haul railways and other railway projects with demanding operational conditions.

High speed rail fastening system products

High speed rail tracks generally rely on the rail fastening systems to adjust the precisions of the ballastless tracks. Our high speed rail fastening system products coordinate the safe and efficient operation of the high speed railway train. We received high speed rail fastening system qualifications which are issued by the CRCC. We manufacture our high speed rail fastening system products based on technological specifications issued by China Railway Corporation and design as set out in our technology licensing agreements with Railway Construction Institute of China Academy of Railway Sciences. Our key high speed rail fastening system products include Spring bar IV fastening system, Spring bar V fastening system, WJ-7 fastening system and WJ-8 fastening system. These products help to maintain the stability and reliability, adjust the height, reduce the vibration of the railway and increase passenger comfort.
