[Alcoa.net] The aluminum alloy door and window industry has developed over a long period of time. It is almost a three-year, one-year change, and a five-year change. There are endlessly competing brands in the market. Door and window merchants are constantly revamping their promotional strategies for the market. However, How to change, for consumers, the more important concern is still in the door and window products themselves. As the saying goes, "a penny and a piece of goods," then in the face of the market price of thousands of doors and windows products, consumers how to distinguish between "ten" and "a thousand" aluminum alloy doors and windows, their differences between the points Where is it? The next one for you to explain. Profile material selection In the selection of profile materials, wall thickness is where consumers need to pay close attention. In general, the national standard aluminum alloy door and window profile thickness of 1.2-1.4mm, but some quality inspection does not pass the door and window brand, the thickness of the aluminum doors and windows used is only 0.6-0.8mm, not only in heat insulation, sound insulation, resistance Aging, corrosion resistance and airtightness cannot be guaranteed. The tensile strength and yield strength are much lower than those of the relevant national standards. They are easily deformed and are not safe to use. In other words, consumers should pay attention to the wall thickness of the main profile in aluminum alloy doors and windows. Repeated inspection of hardware accessories Hardware accessories are frames and fans that connect doors and windows, and are important components for realizing various functions of doors and windows to ensure the performance of doors and windows. It is no exaggeration to say that hardware is the key to determining the length of life of aluminum alloy doors and windows. Different types of aluminum alloy doors and windows have different supporting hardware, but they are all produced according to the same standard requirements. In the "aluminum alloy doors and windows" GB/T8478-2008 the hardware requirements are: opening and closing force, repeated opening and closing performance and other requirements, doors, windows should not exceed 50N of the opening and closing force, can be flexible to open And off. The number of repeated opening and closing of the door should not be less than 100,000 times, and the window should not be less than 10,000 times. The door is opened and closed 30 times a day, and the window is opened and closed 3 times a day, using 10 years of calculation. As for the doors and windows of different architectural buildings for specific projects, the total number of times of repeated opening and closing can be reasonably determined based on their higher frequency of use or age requirements. For consumers, the second part is to check the hardware accessories including corners, upper and lower rail wheels, handles, handle locks, swing hinges, and so on. Good hardware fittings have a flexible and smooth feel during use. The door handle is connected with the door leaf firmly, it is not easy to fall off, and the handle is screwed flexibly. Focus on different functions A good aluminum full gold door and window should meet the requirements specified in "Aluminum Doors and Windows" GB/T8487-2008 and "Aluminum Doors and Windows Engineering Technical Specifications" JGJ214-20010, and also meet the requirements of doors and windows in the region. The performance of aluminum doors and windows is mainly: wind pressure performance, watertight performance, airtight performance, air sound insulation performance, thermal insulation performance, shading performance, lighting performance and other six properties. Different performances have different considerations during the implementation of the installation process. For example, the jointing material and the window frame are closely connected with the sealing paste at the same time, and shall not be loosened. The spacing between the fixing screws shall not be less than or equal to 60 cm. Both ends of the reinforced steel lined with the lining shall be firmly fixed with the opening; see switch parts: open, push or pull Rotating windows should be closed tightly and fluently. This can be confirmed repeatedly; see the frame and the wall should be connected: the window frame should be horizontal and vertical, the same height, the spacing of the fasteners should be less than or equal to 60 cm. The frame and the wall should be connected firmly, to see if there is a gap; see the drainage hole: the drainage hole position is correct, and whether the flow can be used directly to try a small glass of water. The above is the difference between "ten blocks" and "one thousand blocks" of aluminum alloy doors and windows, and certainly not just these. Good aluminum alloy doors and windows will give consumers a good, intuitive consumer experience, more specific identification standards, but also need to study more on their own.
