60kg/m Rail Expansion Joint for Chongqing Hongyancun Bridge

        The 60kg/m rail expansion joint applied to the Chongqing Hongyancun Bridge is primarily used in bridge structures to balance the expansion differences between the track and the bridge caused by temperature, train acceleration and deceleration, and concrete shrinkage, thereby releasing longitudinal stresses such as temperature forces and braking forces. This product features an expansion range of ±400mm, and its trial production and installation have enriched the company's product portfolio.
