Three types of screens are the main market
The reporter visited the market and learned that there are many screens and screen doors on the market today. Invisible screens, pull-down screens, single-door rewinding screen doors, double-door rewinding screen doors, electric rewinding screens, sliding door screens, and folding Screens, magnetic screens, and so on, there are a lot of places to buy, building materials supermarkets, screen manufacturers, small stores near the home can buy.
Although the category sounds a lot, it is mainly divided into three categories: first is a single screen window, is the traditional type, we are more familiar with; followed by the shutter screen, a simple structure, easy installation and maintenance, suitable for maintenance, etc. The principle is similar to that of a roller shutter door. In a frame, there is a window yam that pulls up, pulls left and right, or pulls it from the middle. There is a guide rail on the inside of the frame. There is also an invisible screen window. The invisible screen window is not “invisible†in the real sense. Its design principle is only that the material has a very fine diameter and a high light transmittance. If you do not look closely, it seems that you have no screen.
Domestic or imported
Select yarn first look after touch
The quality of the screens, first of all, is the screen sash, yarns are divided into domestic and imported.
Most of the imports are chemical fiber; glass fibers are made in China, and some are plastic materials. Imported high-quality fiber screens can be tens of thousands of push-pull friction without distortion; domestic glass fiber can only withstand a few thousand times, and plastic screens because of the material relationship, easy thermal expansion and contraction, deformation is very large. Therefore, we should choose imported fiber screens.
According to the staff of Huatai screens, “To judge the quality of screens, you must first look and feel. First of all, check whether the eyelet is even, such as whether the shape of the eyelet is neat, and whether the thickness of the yarn is uniform; secondly, touch the screen and feel it. Slightly scratched, like iron burned with good quality, while the general domestic glass fiber window screening is softer."
"Price learning" is mainly constructed
The construction of screens is also the most important point in the price difference. The most popular invisible screen profiles on the market today are mainly divided into aluminum alloy and plastic steel products.
Shield screens sales staff told reporters: "The main market for steel profiles is engineering, aluminum alloy profile market is divided into two aspects of engineering and home improvement. Home decoration screen life is generally about 5 years. In addition, the invisible screen bearings are also divided into domestic bearings And imported bearings, it is recommended that consumers choose the best imported silent bearings imported.In the choice of the spring is also divided into window springs and door springs.Because consumers can not see the accessories, install the screen door application Look at the effect of the rewind. If the rewind is too slow, the window spring may be used."
“Good roll-window screens, screens are made of nylon-silk piping, and the guide bars inside the guide rails are equipped with positioning rods inside the guide rails. They are both open and ready to seal, and they can be resistant to strong winds. Rolling screens that cut corners and work cuts often save a process. Guide rails are placed on both sides of the guide rails. Window screens are stuffed in directly. When the strong wind blows, the yarn is blown away. Mosquitoes and other insects will enter through the gap and will not achieve the anti-mosquito effect. The bright Angar staff proposed that these are The main factors that directly affect the price of screens.

Avoid using only one summer
Yang Master, who has operated screens for many years, reminds consumers: “Some people are now specializing in the renovation of new communities, renting out stores and selling defective products to residential customers. In addition to seeing the quality of the bearings, screens are best for the purchase of fully enclosed silent bearings.Open bearings can easily enter the dust and affect operation.The quality of springs also determines the length of use.In addition, consumers should buy more Take a few shops to compare and try to buy more famous brands."
In the purchase process must pay attention to product quality and purchasing skills.
