2 ENG In 1964 the American rubber manufacturer General Tire developed a system of expansion joints for bridges called TRANSFLEX. It registered the patent of invention and the trademark worldwide. In 1971 the Expandite Division carried out the first installation in Spain with TRANSFLEX material (Bailen- Ferraz flyover in Madrid). In 1997 the Trelleborg Group integrated the Expandite Division into its organisation. At the present time Trelleborg IESA, a company within the TRELLEBORG Group, has the rights of ownership trademark, manufacture and distribution, which are carried out through its Expandite Division. Brief description product The TRANSFLEX system consists of rubber moulded s reinforced with steel. TRANSFLEX is supplied in s of a specified length and are anchored to both sides structural joint.. There is a wide range of s that absorb movements up to 330 mm in length, including those produced by skew joints. Their main functions are to absorb these movements, ensure quiet traffic and provide effective sealing joint on the road surface. Characteristics The joint absorbs movements up to 330 mm in length Modules are rubber coated to protect the reinforcements They ensure comfortable travel over the joint Extraordinary durability. Possibility of absorbing skew movements. Easy, fast assembly when replacing old joints The impact loads are fully absorbed by the system.

4 Special parts. The formation of special parts for kerbs, pavements or other reliefs is offered for all the Transflex models to ensure continuity sealing. Examples: Transflex, s 1, 200, 2 and 300 Skew case Transflex, s 400, 6, 900 and 1300 Change in level of pavements To order the manufacture se parts it is essential to specify all the dimensions.
