DYWIDAG Post-Tensioning Tendons installed in Bridges of a Traffic Interchange Kallang-Paya Lebar Expressway (KPE), Contract 422. The Kallang-Paya Lebar Expressway (KPE) is another project of the Land Transport Authority`s effort to improve the road network in Singapore. Members of the Institute include major post-tensioning material fabricators in the U.S., Canada and Mexico, and manufacturers of prestressing materials in the U.S., Canada, Mexico, Asia and Europe, and companies supplying materials, services and equipment used in post-tensioned construction. 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. 2 The Williams System Williams Prestressing / Post-Tensioning Systems consist of high tensile steel bars available in seven diameters from 1" (26 mm) to 3" (75 mm) with guaranteed tensile strengths to 1027 kips (4568 kN). DYWIDAG Multistrand Anchors tie down a Dam in Nepal Middle Marsyangdi Hydroelectric Project, Lamjung. In mountainous Nepal the power of water can be seen time and again during the rainy season. DYWIDAG Strand Post-Tensioning Systems, DYWIDAG Bar Post-Tensioning Systems and DYNA Grip® Stay Cable Systems offer you durability, safety, quality and reliability and are tailored to suit your totype DYWIDAG Post-Tensioning System using bars was the arch-bridge Alsleben (Germany) in 1927. From that time on DYWIDAG has continuously improved its systems to keep up with the growing demand of modern construction technology. In addition to the traditional post-tensioning system using bars, that is mainly geared towards geotechnical Date: 1/1/2006.
