Reinforcements in the PVC profiles

td br What are steel reinforcements in PVC?

The PVC material itself is not stiff enough to ensure sufficient stability and strenght of the window. The chamber structure of the profiles however allows using in them so called sections which are galvanized steel elements. Thanks to them the construction of the window becomes stronger. They are placed on the perimeter of the frames and sashes. Regarding the shapes we distinguish open and closed reinforcements.
