Bridge Bearing Pads

Bridge Bearing Pads are specially designed with one or multiple layers of elastomers that are bonded to internal steel laminates. These bearing pads are widely used in the construction of bridges and other structures for bearing the vertical load. These elastomeric bearing pads are available in compliance with the latest standards of IRC : 83 (Part II) – 1987.
