However, steel doors and windows are still a new type of building materials in China after all, and most people are still unfamiliar with it. So, how to identify the advantages and disadvantages of steel doors and windows? First of all, it should be made clear that plastic steel doors and windows, like other building materials, have high, medium, and low grades, as well as high quality and inferior quality, and cannot be confused. Differences between the quality of steel doors and windows and grades are mainly divided into the following aspects: First, we must first understand the UPVC profiles used for plastic doors and windows. UPVC profile is a decisive factor in the quality and grade of plastic steel doors and windows. A good UPVC profile should be a reasonably designed multi-cavity, wall thickness, formula containing anti-aging, anti-ultraviolet auxiliaries, from the appearance point of view should be smooth surface, color white and blue . Specially to remind everyone that there are many people think that plastic windows are the same white, in fact, otherwise, high-grade UPVC profiles should be white in the pan-blue, such color anti-aging properties, outdoor wind and sun in the third five Ten years will not be aging, discoloration, deformation. The middle and low-grade profiles are white and yellow, this kind of color sunscreen ability is poor, after using a few years will become more and more yellow until aging, deformation, embrittlement, the reason is that the profile formula contains too much calcium. Everyone has been widely used in the past few years, but nowadays it has become clearer in the calcium plastic window. Therefore, we must carefully choose UPVC profiles, manufacturers can ask for different sections of profiles to compare together, you can see at a glance. The second is to look at the hardware selected for the doors and windows. The hardware of high-end doors and windows is made of metal. Its inherent strength, appearance and usability directly affect the performance of doors and windows. Many middle and low-grade steels use plastic hardware, and their quality and longevity have great hidden dangers. The third is to look at the quality of the assembly of doors and windows, mainly to see whether the appearance of smooth and non-destructive, whether the welding angle is neat, whether the hardware is aligned, with or without steel lining. The most important point is that we must check whether the production licenses issued by the construction companies of the door and window manufacturers are not negotiable. We must not use steel windows produced by street workshops. The quality and reputation of these windows cannot be guaranteed.
