Expansion joint type

Bridge expansion joints GQF-C, GQF-Z, GQF-E, GQF-F, GQF-MZL are all bridge expansion joints designed with hot-rolled integrally formed special-shaped steel. Among them, GQF-C, GQF-Z, GQF-L, GQF-F bridge expansion devices are suitable for bridges with expansion and contraction of less than 80mm. The modular bridge expansion joint device composed of a linkage mechanism is suitable for large and medium span bridges with an expansion volume of 80mm-1200mm.
