Finger Joint

Datong Finger joint systems are expansion joints for movement up to 880mm, and especially suit for bridges with heavy vehicle loading. Finger joints are anchored at both side of bridge deck. A drainage channel, hanging beneath the joint and connected to either side of bridge gap.

Compared with modular expansion joints, the orientation of the fingers, in the direction of vehicle travel, minimizes noise emissions and maximizes driver comfort.

Thanks to its excellent noise-reducing properties, finger joints are ideal for bridges and roads near residential or other noise-sensitive zones and suitable to heavy traffic load and large movement range bridges.
