What we make

The complete AT type post-tensioning anchorage, in five standard models from 4 to 19 strands and up to 400 t UTS. Every part of one anchorage ships together as a matched kit; only the strand is by others.

What we do on site

TYROS crews install, stress and grout the tendons we supply: duct and anchorage installation, strand threading, multi-strand stressing to 80% of UTS with calibrated jacks, elongation checks against design, lock-off and grouting, with a record for every tendon. Girders and pier caps, on the casting bed or in place.
