We sell and provide various sizes and specifications of finger joints for bridges and overpasses. Is a type of expansion joint made of steel and shaped like 2 combs that bind to each other. Finger joints are also called multi-gap because they have many gaps. It can be described that this type of connection has a shape like the fingers on both hands that are fused together so that it is called a finger joint.
Multi gap joints can accommodate movements from 75 mm. Because it is an open expansion joint, a good drainage system is needed at the bottom of the joint to damage the concrete layer underneath.
