Why to use galvanized steel reinforcement for upvc windows:
Doors and windows in the building to withstand the impact from the environment, mainly wind pressure and rain and snow attack, but also to withstand the use of switching force and its own gravity. Wind force is the main reason for the bending deformation of doors and windows (horizontal bar, vertical bar, window lattice) and frames and fans. Whether the doors and windows are safe depends mainly on their ability to withstand wind force, which is usually measured by the gas pressure per unit area.
The mechanical properties of rigid PVC plastics are much worse than those of steel, aluminium and wood. Especially, the bending strength of rigid PVC plastics is only 1/4 of wood, 1/28 of aluminium and 1/84 of steel. The bending performance of rigid PVC plastics profiles is much worse under the same cross-section shape and size as that of aluminium and steel profiles. In order to remedy this shortcoming, the section size of rigid PVC profiles used for making doors and windows is larger than that of steel and aluminum profiles. At the same time, the mechanical properties of its cross-section shape are as reasonable as possible to meet the stress conditions of doors and windows. The above methods can not fully meet the mechanical properties of doors and windows. Another important measure is to install steel reinforced steel lining in the cavity of PVC plastic profile when the single profile of doors and windows exceeds a certain length.
