Void formers tubes obtain very high radial rigidity by means of special corrugations and are thus highly suitable as void formers these tubes are embedded, thus reduce the dead weight of the structure.

Area of use

In building projects such as bridges and quaysides, void tubes make possible large spans thanks to reduction in dead weight and thus permit good technical, aesthetic and economic solutions.

• Void forming tubes meet the requirements of     concrete structures for highly rigid but light sheet     metal tube that can withstand being embedded     without deformation.
• The seam is entirely tight, thus preventing water     from entering the tube.
• The low weight makes tube handling easy and their     internal seams and corrugations ensure that the     tubes did not catch on each other, facilitate the     mounting of female ended cones or caps.
• Void formers are sealed with end cones that are     supplied, fitted to the tubes.
• Void formers are withstanding reinforcement loads      & transportation as well fast tempo casting.
