Since the early 1960s The D.S. Brown Company has provided expansion joint systems and structural bearing assemblies for bridges around the globe. Bridge expansion joint systems are directly exposed to vehicular wheel loads and, therefore, must resist dynamic forces causing fatigue and wear. In addition, these expansion joint systems must remain watertight to protect the bridge superstructure and substructure from corrosion.
