UPVC window and door are the most commonly used building materials in home decoration. Plastic-steel doors and windows have a multi-cavity structure, which has good thermal insulation properties, and has good performance in terms of appearance, color, and corrosion resistance. What skills does LUMEI Profile teach you to distinguish the quality of plastic steel doors and windows?
1. The profile quality of UPVC window and door. The appearance of the profiles should be observed, and attention should be paid to whether the colors of the frames and sashes that make up the doors and windows are consistent, whether the appearance is uniform, and whether the cavity distribution is reasonable. Normal plastic-steel doors and windows usually have shiny and tough surfaces.
2. The gap and sealing of UPVC window and door. Check whether the fit gap between the various profiles is tight, whether the cuts at the mating parts are flush, the height difference of the lap joints of the profiles, and so on. Generally, for plastic-steel doors, the main considerations are the gaps between door frames and sashes, door panel battens, door panel edging, and various profile joints of shutters, sealing strips, etc.
3. Welding of UPVC window and door. It depends on whether the welding place is flat, whether there are cracks, whether the inner and outer corner seams are clean and beautiful, use a box ruler to measure the diagonal size of the plastic steel doors and windows, the diagonal size difference should not be more than 3mm, the diagonal difference The smaller the display, the finer the craftsmanship, which is also conducive to installation.
4. Hardware of UPVC window and door. The quality of hardware also has a certain impact on the life of doors and windows. The hardware used should look thick, and the surface gloss should be good, the protective layer is dense, there is no scratches, and the most important point is that the opening should be flexible.
5. Reinforced steel for UPVC window and door. According to national standards, there are different requirements for the wind pressure resistance of plastic steel doors and windows. The inner cavities of the frames and fans of plastic steel doors and windows need to be equipped with reinforced steel to ensure the robustness and service life of the product. In order to reduce costs, some manufacturers do not install or install reinforced steel that does not meet the requirements.
6. The usual inspection methods for UPVC window and door are:
1) Estimate by using the weight method, that is, weigh the weight of doors and windows, the weight of the doors and windows with reinforced steel is heavier, and vice versa.
2) Use magnets on the frames and sashes of doors and windows. If magnets are attached, there will be reinforced steel in the profile, otherwise there will be no.
3) Observe whether there are screws to fasten the section steel on the frames and sashes of the doors and windows, and it can also prove whether the reinforced section steel is assembled.
In summary, although the decoration price of UPVC window and door is relatively expensive, it takes a long time to use, and UPVC window and door have other advantages.
