How is the usage of plastic-steel windows in foreign countries?

In Europe, Japan, and North America, hard plastic (U-PVC) doors and windows are the main types of doors and windows used in residential buildings. This is mainly due to several obvious comparative advantages of plastic-steel doors and windows, such as high processing standardization, high processing efficiency, low cost, and good insulation and soundproofing performance. However, in China, during the fierce competition, the material composition, processing technology, and quality standards of plastic-steel materials and factories are not standardized, resulting in common quality problems such as material discoloration, frame deformation, and poor opening and closing of plastic-steel doors and windows after exposure to sunlight. As a result, domestic consumers have lost trust and confidence in plastic-steel windows. The following are a brief introduction to the comparison of plastic-steel doors and windows:

Processing automation has achieved a high degree of standardization from material to finished window, high processing efficiency, and low unit area cost: plastic profiles can be extruded to achieve the co-extrusion of steel plates, plastic materials, and rubber strips, and the U-slot hardware of plastic-steel windows can also achieve automated production with material preparation, surface treatment, and assembly. Profile cutting is done using a cutting saw, profile processing is completed by a milling machine, and the frame assembly is completed by a corner welding machine in one go. The hardware installation of plastic-steel windows adopts in-place positioning and positioning, which is ensured by the special U-slot structure on the plastic-steel window profiles. The installation and fixation use simple screwing methods, and the two major installation steps of the hardware can be achieved through precise processing by the mechanical arm for automation and continuous production. In developed countries, the most expensive factor is labor cost. The above material and window processing automation have led to the unit area cost of plastic-steel windows being approximately 15% to 25% lower than that of aluminum windows with the same performance. Therefore, large-scale window manufacturing enterprises in Japan, Europe, and the United States are mainly focused on plastic-steel windows.

Good insulation and soundproofing performance: The material properties of U-PVC profiles determine that they have better insulation and soundproofing performance compared to metal materials.

Whether in Europe, Japan, or the United States, the plastic-window industry shows a highly concentrated feature. This is because the several major manufacturing processes of window production, such as profile processing, frame assembly, and hardware installation, can all be automated in the plastic-window field. Automation production leads to high product standardization and prominent price advantages, and product performance can also meet usage requirements. Therefore, foreign plastic-window enterprises are either extremely large in scale or have a secluded position, and the phenomenon of extreme polarization is very prominent. Compared with the domestic situation, only a few enterprises can achieve automation or semi-automation in plastic-window production. This is not the development bottleneck of domestic plastic-window enterprises. The biggest challenge for domestic plastic-window enterprises is the quality misconceptions and price biases of consumers regarding plastic-window products. Changing people's cognitive inertia seems to only rely on time and patience.
