Trelleborg Bridge Expansion Joints Transflex® - Trelleborg AB

Transflex®worldwide expansion joints

We have supplied and installed Transflex®expansion joints worldwide since 1974. The Transflex®device consist of steel reinforced rubber modules, designed to absorb the expansion, contraction, translation and rotation movements of road bridges, with remarkable comfort to traffic, effectively sealed, low maintenance and easy replacement.
The Transflex® range is supplied in modules of a given length and they are anchored to both sides of the structural joint.
All Transflex® models offer the possibility to make special pieces for kerbs, walkways, correction of skewed joints and other contours.  In this way, the continuity of the seal is ensured.

Features, Benefits and Service

Features  

  • The rubber covers the steel reinforcement that entails a double benefit: the rubber protects the metallic part from corrosion and the steel reinforces the device structure.
  • The rubber used is highly resistant to wear produced by tyres, to impacts and weather. Transflex® devices are designed to endure with time.
  • The joint design includes drain channels that provide quick water removal preventing water stagnation. This delays the aging of the joint and reduces the possibility of accidents.
