    Precontraint 705

    705 is a UV-resistant all-round pvc of only 670 gsm, suitable for covers, sun seals, halls and many more applications. Precontraint - is French and means stretched. Serge Ferrari is alone in the world of stretching the ground fabric before it is coated with PVC. The result is a PVC that does not stretch, and that the wear surface becomes completely even over the entire surface. But can thus use a lighter PVC from Serge Ferrari and get the same results regarding wear surface as a significantly heavier PVC without stretching.
