Bridge expansion joints are installed between the bridge structure and its fixed sections at its both ends, absorbing the expansion and contraction of the bridges. They comprise steel angles and steel bridging plates coated with a special rubber or flexible elastomer. KOHRANG elastomeric expansion joints are designed and manufactured considering various kinds of steel and concrete bridges and their expansion or contraction level in summer and winter. They also adjust the transitional and rotational movements of the bridge structure. Considering the high costs of these parts’ repair and replacement and also the related induced traffic problems, the quality and the service life of them are so important. The used elastomer materials are corrosive resistance against oil, hydrocarbons, salt, sand and abrasion. KOHRANG elastomeric expansion joints are capable to sustain the vehicles-induced horizontal loads as well as the movements without damaging the surface.
