method of purchasing plastic steel doors and windows
1. Thick profile
The first thing friends should observe when purchasing plastic steel doors and windows is the material of plastic steel doors and windows, which is usually called UP-VC profile. Generally, UP-VC profiles with good quality are designed with multiple cavities, and the walls are very thick; However, the wall of inferior plastic steel is relatively thin.
2. The color is "blue" and white
Secondly, when choosing plastic steel doors and windows, we should also look at the color. High-quality UP-VC profiles are made with anti-ultraviolet additives and anti-aging agents, so the quality of plastic-steel doors and windows with white and blue appearance is better, and these plastic-steel doors and windows feel smoother. This kind of UP-VC profile also has good performance, that is, it does not deform, age or fade. And if the appearance color of the plastic steel doors and windows you buy is too white or gray, it means that the stable components in the material are not enough, and it is easy to age and turn yellow over time.
3. Glass
In the process of purchasing plastic-steel doors and windows, we need to look at the glass of plastic-steel doors and windows in addition to the profiles. The glass selected for high-quality plastic steel doors and windows is generally flat, and there is no water ripple, and its installation should be relatively firm, and the glass installation will not directly contact the plastic profile, and generally the sealing bead is used to stick to the gap. If the plastic-steel doors and windows you choose are double glass interlayers, then make sure there is no dust and water vapor in the interlayer.
4. aluminum slide rail
then, when observing the plastic steel doors and windows, it is necessary to determine whether there is an aluminum slide rail under the window frame of the sliding window. The aluminum slide rail is installed to facilitate its replacement, and the aluminum slide rail on the plastic steel doors and windows is best to choose double slide rails. All of the above must be carefully checked before installation. When installing plastic-steel doors and windows, it is necessary to ensure that the whole surface is smooth and flat, and there is no welding fracture. The door window frame and fan profile should also be embedded with special steel lining.
