Seismic Transflex®1600-6400 - Seismic Bridge Expansion joints - Trelleborg Bridge Expansion Joints

Seismic Transflex®1600S - 6400S

The demand of expansion joints that support larger movement ranges increases, as the span of new structures increases. The answer to this challenge is this Seismic Trasflex®model, suitable not only for structures in seismic areas, but also for bridges and viaducts with large spans. The Seismic Transflex® expansion joints consist of one or two movement modules which are the “mobile” sections of the joint, made of rubber and steel, aimed to accommodate the expected movements. And the bridging module which is the “fixed” section of the joint, aimed to bridge the structural opening. The Seismic Transflex®expansion joints allow absorbing large movements, while providing remarkable comfort to traffic, effective sealing, low maintenance and easy replacement. High Movement Seismic Transflex®models are numbered from 1600 to 6400, and cover a movement range from 350mm to 1440mm.
