Applications

Steel plate finger type expansion joints for bridges are suitable for use under heavy traffic, and mainly applied to the device with 20-320mm expansion. Their special doweled connection system makes them particularly useful where the impact on the main structure should be minimised. Finger type joints are still specified on many bridge projects due to proven long-term structural performance. These joint systems are also convenient to install on bridge rehabilitation projects requiring a shallow joint depth and/or staged construction.
