How to recognize good quality and bad quality windows:
First of all, we should make it clear that plastic steel doors and windows, like other building materials, are high, medium, low-grade, high-quality and low-quality, can not be confused. The main steps to distinguish the quality and grade of plastic steel doors and windows are as follows:
The first step is to understand the UPVC profiles for plastic steel doors and windows. UPVC profile is the decisive factor for the quality and grade of plastic steel doors and windows. A good UPVC profile should be reasonably designed with multiple-chamber, wall thickness, anti-aging and anti-ultraviolet additives in the formulation, and its surface should be bright and white in appearance.
The second step is to look at the hardware selected for doors and windows. The hardware of high-grade doors and windows are all made of metal. Its internal strength, appearance and usability directly affect the performance of doors and windows. Many middle and low grade plastic steels are made of plastic hardware. There are great hidden dangers in their quality and life.
The third step is to look at the quality of the door and window assembly, mainly to see whether the appearance is clean and non-destructive, whether the welding angle is clean and tidy, whether the hardware is well matched, whether there are steel linings and so on.
