rubber China 80mm movement steel bridge expansion joint

Modular expansion joint are the most frequently employed types of expansion joints in road bridges.Byspecial steel welding elements arranged side by side and equally controlled they are supported on special load carrying and control systems, intermediate sealing elements with form- and force-fit clamping as well as marked by a continuous anchorage in the structure with permanent connection to seal and coating.

Single gap expansion joint is a strip seal joint, which consists of two steel edge profiles with anchor loops and a replaceable sealing profile. The strong anchor loops ensure the reliable anchorage of expansion joint with bridge structure. On the anti-corrosion side, the steel profiled should be in accordance with ISO12944 or other national standard as requested,such as ASTRA, RVS and ACQPA.The sealing profile is firmly connected with the steel edge profiles and meanwhile it ensures 100% water-tightness.
