Steel expansion joints for movements of up to 80 mm are expansion joints made of a single set of structural steel, rubber sealing strips and dowel rods. According to the cross-sectional shape, they are divided into 5 types, including GQF-C, GQF-F, GQF-E, GQF-Z and GQF-RG. Being fully anchored within the depth of the road surfacing, strip seal expansion joints can prevent roads from cracking caused by climatic change.
In order to meet the requirements of the bridge deformation, strip seal expansion joints are usually set at each end of the
bridge, between ends of the beam and abutment or on the hinge joints of the bridge. They are applied with rubber noise weaken board which can help to increase movement and reduce noise from over-passing traffic by up to 80%.
