As the old saying goes, Artie is bold. Do not think that living in a high-rise locked door will not be stolen, and now the thief is not only "art high", courage is particularly large, climbing the window through the window to steal, many people are deeply affected. In the cold weather in winter, people are hiding in bed and sleep. The vigilance is lower than usual, so the burglar moves. The function of the anti-theft window appeared at this time. Do you know which kind of material is used for the anti-theft window? How to buy it? There are also various anti-theft windows in the market. Some are designed in the middle of the glass, some are designed outside the windows, and some hidden security windows are also very convenient. The function of the anti-theft window is not just anti-theft protection. Family safety is also a very important feature. If you are about to buy anti-theft windows, you may wish to learn more about the security windows. Plastic-steel windows are the most popular at present, so the selection of them also requires special care. In general, as long as you pay attention to the following aspects, you can ensure that your choice of products is the best: (1) Select profiles. From the current point of view, most houses belong to high-rise buildings, and the area of ​​windows is generally relatively large. Therefore, when selecting profiles, it should be noted that the wall thickness of the profile should be greater than 2.5 mm, and the thickness of the lined steel plate should not be less than 1.2 mm. (2) Check the surface quality of the material. The color of the plastic surface should be ivory or blue and white, and it is very clean, smooth, smooth, there is no large area of ​​scratches, bumps, welding mouth without opening, fracture. If its color is too white or yellow, it means that the stable composition of the material is not good, and it will deteriorate easily after a long time. (3) Check the glass and hardware accessories of the window. The glass of the window should be flat, free of water, and securely mounted. In the case of double glazing, there should be no dust and moisture between the two layers. The hardware accessories for the windows should be complete, in the right position, securely installed, and flexible to use. Generally, the hardware accessories for high-end windows are made of metal. Its internal strength, appearance, and performance are all very good. Many middle- and low-grade plastic windows are available. The use of plastic hardware accessories has hidden dangers in its quality and longevity. (4) Check the relevant documents. At the time of purchase, it is necessary to check whether the manufacturer of the doors and windows has issued a production license issued by the local construction committee, so that it is possible to ensure quality and reputation. When purchasing aluminum alloy windows, as long as you pay attention to the following aspects, you can ensure that you buy more attractive products: (1) Look at the thickness of the material. Aluminum alloy windows generally have 55 series, 60 series, 70 series, and 90 series. Series numbers indicate the thickness of the thickness of the structure in millimeters. When selecting different series of windows, it should be determined according to the size of the window hole and the local wind pressure value. If you are using an aluminum alloy window as a closed balcony, you should choose a series of less than 70. The thickness of the window is generally 1.2 to 2.0 mm, the tensile strength should be 160 N/mm2, and the yield strength should be 110. If you think that this data is difficult to measure accurately, you can bend the profile by hand during the purchase process to see if it can be restored to its original state after being released. It is a qualified product that can be restored to its original shape. (2) Look at the color of the material. The color of the aluminum alloy profile should be consistent, if the color difference is obvious, do not buy. If you find that the surface of the aluminum alloy profile has sunken or bulging, you should also choose carefully. (3) See the gloss of the profile. If there are obvious defects such as white spots (open bubbles), black spots (ash), cracks, burrs, and peelings on the surface of the aluminum alloy window, it is better not to purchase it even if the selling price is relatively low. (4) Look at the oxide film thickness. True qualified aluminum alloy window, its oxide film thickness should reach 10 microns, if you do not know how to measure this, you can lightly tap on the surface of the profile to see if the surface of the oxide film can be erased. Can be easily wiped off, then the quality of this aluminum alloy window is not qualified. (5) See processing. Most of the high-quality aluminum alloy windows are finely processed, the installation is particular, the sealing performance is good, and the switches are free; while the poor quality aluminum alloy windows are made with rough workmanship, the sealing performance is poor, the switch is not free, and there is leakage of air or glass after installation. Shock and other phenomena. (6) Look at the price. Under normal circumstances, the production cost of high-quality aluminum alloy windows is relatively high, so the price is also about 1/3 higher than that of inferior aluminum alloy windows. The reason why the inferior quality of aluminum alloy windows are so cheap is mainly because they use materials whose wall thickness and tensile strength and yield strength are lower than the relevant national standards. Such windows are unsafe to use, so they are buying such When it comes to windows, it is good to use the products of regular aluminum alloy door and window manufacturers. Third, anti-theft window purchase wooden anti-theft window selection method The selection of wooden windows is mainly the selection of styles and wood. The wood is generally dominated by larch and eucalyptus. These can be selected according to individual conditions and are better identified. Therefore, we will not talk about it any more.

We must choose the most suitable anti-theft window according to the actual situation of our family. Nowadays, there are many brand styles of plastic windows and aluminum alloy windows on the market, and the prices are also very different. Consumers are generally difficult to choose, so we will focus on introducing these two aspects of knowledge. security window Allen Bolt,stripped allen bolt,csk allen bolt,flat head allen bolt Jiangsu Minglu Stainless steel Co.,ltd , https://www.minglubolt.com
