Modular expansion joints, also called GQF-MZL modular bridge joints, are composed by boundary beams, middle beams, cross girders, displacement control systems, bridge bearings, anchoring components and rubber sealing belts. modular expansion joints are suitable for longitudinal movements of 80 mm to 1200 mm.
Having good bearing capacity and stability, modular expansion joints can accommodate movements in every direction and rotations about every axis. Their individual displacement control and load transfer systems enable bridges to adapt the movement of the beam caused by temperature and ensure the traffic safety.

Modular expansion joints for longitudinal movements of 80 mm to 1,200 mm can be widely applied on the bridges which are slope, wide, curved and skew. They are used in highway bridge decks, bridgehead and other places to prevent bridges from appearing cracks cause by climate change. It also can be used in expressway.
