UPVC Profile Door & Window is an indispensable and important part of the building, which not only bears the influence from the environment, but also the damage from man-made. Here's a look at some of the steel linings in UPVC Profile Door & Window.
UPVC Profile Door & Window is attacked by wind pressure and rain and snow, as well as opening and closing force and its own gravity. Among them, the wind force is the main reason for the bending deformation of the rods (transversal stiles, mullions), frames and fans of doors and windows. UPVC Profile Door & Window without steel lining can only be regarded as plastic doors and windows. The real UPVC Profile Door & Window is to join reinforced steel. The wind pressure resistance performance of UPVC Profile Door & Window mainly depends on the specifications of the reinforced steel added in its cavity. Not easy to deform.
For UPVC Profile Door & Window, here is a special reminder that the upper and lower horizontal edges of the window sash should be lined with steel. If the upper and lower horizontal edges of the window sash are not lined with steel, the plastic steel doors and windows produced in this way are cheap, but soon after use, the window sash will not be lined with steel. It will be deformed, resulting in air leakage and water leakage. Also, the incisions of the fan and frame steel lining should be chamfered at 45 degrees.
It is not enough to just increase the profile steel, but also to fix the profile steel and the profile together. At this point, the doors and windows made by some manufacturers can generally increase the strength of UPVC Profile Door & Window.
In addition, the steel lining must be galvanized anti-corrosion treatment, which has extended its service life. The steel lining is divided into two types: the open U-shaped steel lining and the seamless (with weld) square steel. The strength of the square steel of the same specification is obviously better than that of the U-shaped steel lining, especially for the frame and frame of the doors and windows of high-rise buildings. Steel, and do wind pressure strength calculation.
Consumers have the following ways to identify whether UPVC Profile Door & Window is equipped with steel lining:
1. From the weight, you can feel whether steel lining is added to UPVC Profile Door & Window. If the weight of UPVC Profile Door & Window is relatively heavy, it means that steel lining is added, otherwise there is no.
2. You can carefully observe whether there are self-tapping nails on the outer wall of the window frame and window sash. Because the steel lining of plastic steel is to be fixed with the plastic profile, it must be fixed with self-tapping nails, so look at the window frame or window sash. Whether there is a nail cap on the outer wall of the plastic steel is also a way to check whether the steel lining is added to the plastic steel.
3. Magnetite can also be used to verify whether there is a steel lining in the plastic steel.
