Bonded DYWIDAG Strand Tendons – for challenging Construction Projects
Thanks to their special material properties, DYWIDAG Strand Tendons are the optimum solution for post-tensioning LNG tanks with very low working temperatures. You can use our systems worldwide in demanding cryogenic applications during the construction of LNG and LPG Tanks – permanently and safely.
Unbonded DYWIDAG Monostrand Tendons – economic and efficient
Are you looking for a Post-Tensioning System that can be installed efficiently and quickly in floor slabs, flat slabs and barrier systems? DYWIDAG Monostrand Tendons comply with national norms and have been ensuring the construction of light-weight and efficient flat slabs and fast construction progress for many years. This is how we make your construction project more profitable.
External DYWIDAG Strand Post-Tensioning Systems and Wire EX Tendons – a Maximum of Flexibility
Our external post-tensioning tendons are used around the world for the construction of bridges and wind energy structures. The strands and wires can be restressed and replaced individually, thus offering maximum flexibility for your project.
DYWIDAG Bar Post-Tensioning Systems – A successful Tradition
The first ever structure built with a prototype of the DYWIDAG Bar Post-Tensioning System was the Alsleben arch bridge in Germany in 1927. In that year, a tradition began that we have successfully continued on a global scale until today. DYWIDAG Bar Tendons are mainly used for repair and strengthening. Our bar tendons are also used for a permanent, force-fit connection of concrete and steel such as they are needed for the construction of wind towers or other structures. Our systems can be used as bonded or unbonded bar tendons as well as external tendons for a large variety of applications.
DYNA Grip® Stay Cable Systems – Aesthetics and Reliability
We have been significantly involved in the development, construction, and execution of support cables, cable-supported structures and stay cables since 1970. Our economic and high-performance Stay Cable Systems are the essential components of aesthetic bridge structures in many projects around the world. They reliably transfer the loads to the foundation via the pylon and are long-lasting and easy to maintain.
DYNA Grip® Stay Cables
are retensionnable and replaceable – designed for a long service life of your bridge structures. You can count on the quality of our Stay Cable Systems: They comply with international requirements of organizations such as PTI, fib or CIB/Setra.
