A girder, ready to be stressed.
A live TYROS site. The girder's end face carries the anchorages; the jacks on the gantry above will pull every tendon to 80% of its strength.
Five heads. One system.
Every AT anchorage shares the same cone, wedge and spiral design — sized from a 4-strand tendon at 75 tons to a 19-strand tendon at 400 tons.

Built into the structures that carry cities.
Pre-stressing has replaced conventional construction wherever spans get long and sections get slender. TYROS anchorages are specified across all of them.
From forged steel to stressed strand.
The TYROS "AT" type anchorage system has been designed considering the increasing needs of pre-stressing systems of the Global Construction Industry and manufactured with well proven materials while maximizing the cost effectiveness. Today pre-stressing technology has taken over the conventional methods used in building Bridges, Buildings, Metro rails, Flyovers, Tunnels, etc.
