Bridge Single Gap Expansion Joints AR-EX HS 100 are commonly used in expansion joints for movements of 100 mm or less. Short span bridge decks do not experience large changes in length due to temperature changes etc. The ability of an expansion joint to prevent leakage of surface water to the structure beneath is a critical factor to avoid serious damage to the bridge support system. Expansion joint type selection depends on the bridge structure. The chosen expansion joint type must be able to facilitate all movements in all directions and rotations.

Arsan AR-EX HS single gap expansion joint consists of two steel profiles with anchor loops and a replaceable and %100 watertight seal. Arsan special sealing profiles allow arranging the maximum movement of single gap expansion joints up to 200 mm according to project requirements. Arsan rubber seal design ensures %100 water tightness with tests. Sealing elements are in EPDM or CR material. Rubber seal between steel beams consists of an elastomeric sealing element with a special shape. The edge beams are rigidly connected to the main structure by means of anchors directly welded to the edge beams.
