Post-tensioning (or prestressing) is a process that uses high-strength materials such as cables or anchored bars to reinforce the structural elements of a construction.
The method involves applying a compression force on the concrete to actively counterbalance the effective forces of the structural element (notably the traction resistance).
AGF Steel teams are the leading post-tensioning specialists in Canada. They have the necessary equipment and know-how to tackle all types of projects, regardless of their size and complexity.
