The pre-stressed concrete combines two materials of high quality: concrete and steel; It provides the best of both. It is easily adapted to the manufacturing of components in series.
The pre-stressed concrete eliminates cracking, improves the material’s efficiency by using the whole section, and allows the lightning of buildings and the crossing of great spans with low heights.
The slender aspect of the products is aesthetic and pleasant, they need no maintenance, the insurance premiums are reduced and they offer a fire resistance generally sufficient without onerous special additional treatment.

Finally and above all, the pre-stressed concrete allows considerable savings of concrete and especially of steel, the latter in a ratio which can reach 50%.
