Stay Cable Strands
Designed to be maintenance-free.
- Hold Downs
- Extradosed Cables
DYWIDAG multistrand Stay Cables use strands as the main tensile element that meet the requirements of fib and PTI-Recommendations for stay cables, ASTM, BS as well as other national or international standards.
Strands are anchored with specially treated 3-part wedges and with wedge teeth penetrating directly into strands wires,. Wedges are characterized by high fatigue resistance.
Specially designed wedges for use with Epoxy Coated Strand are available, too. Here, wedge teeth penetrate through the epoxy coating so that they grip into the wires of the strand. Cold-drawn 7-wire strand is coated with epoxy resin in the shop. An additional PE sheathing on top of the epoxy coating is possible, protecting strands from damage during handling and on-site installation
