In the selection of plastic doors and windows must first clarify that plastic steel doors and windows, as with other building materials products, have high, medium and low grades and high quality and poor quality, can not be confused. Differentiating the quality and grade of plastic steel doors and windows is mainly divided into three steps.
The first step is to first understand the UPVC profiles selected for the steel doors and windows.
UPVC profiles are the decisive factors for 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 of the surface should be smooth, color Green and white. In particular, to remind everyone that many people think that plastic windows are all the same white, but it is not. High-grade UPVC profile color should be white and blue, this color anti-aging performance is good, in the outdoor wind and sun will not aging, discoloration, deformation. The middle and low-grade profiles are white and yellow, and the sunscreen is poor in color. After a few years of use, the sun will be yellowed until it ages, deforms, and becomes brittle. The reason for this is that the profile formulation contains too much calcium. You can ask the manufacturer to ask you to compare different profile sections together, and you can see at a glance whether you are good or bad. At present, domestic profiles that are better include Conch, Vicat, and Ke Mei Ling. Among them, Conch Profile is the largest profile production plant in the country and it has introduced the latest equipment from Germany and Austria in the 1990s. It is one of the most well-known profile brands in China.
The second step is to look at the hardware selected for the door and window.
Hardware is very important for 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 plastic steel windows use plastic hardware, which has great potential for quality and longevity.
The third step is to look at the quality of the assembly of doors and windows.
Mainly whether the appearance is smooth and non-destructive, whether the welding angle is clean and tidy, whether the sliding window is flexible, whether the opening window is open freely, whether the doors and windows are sealed tightly, whether the hardware is aligned, whether there is a steel lining and so on.
We constantly invest in research and development so as to ensure that our products will always be a step ahead of competition.
