We produce various of bridge expansion joints including modular expansion joints, finger type expansion joints, elastomeric rubber bridge expansion joints and asphalt expansion joints, they are used on highways and briges to reduce the vibration and pressure from the various of traffic tools when they pass through, in this way to protect the highways and bridges.

Finger-shaped expansion joint is a packaged type expansion device an mainly applied to the device with the extension 20-320mm.This type of expansion joint mainly comprises of elastomeric strip fixed on and connects with two sides of joint and the whole of finger shape plate and moving finger shape plate that can fit together with racks.

The fixed plate and moving plate connect to bridge deck by anchor parts.And the movement of moving finger shape plate achieves the extension and contraction of this type joints without longitudinal transion clearance.
