First: Materials

the main materials of doors and windows generally include three aspects: aluminum profile, glass and hardware. When choosing products, owners often pay more attention to the thickness of aluminum profile and glass, but the requirements for hardware are not very high, which is not comprehensive. In fact, the state has certain standards for colored aluminum windows. The thickness, strength and oxide film of aluminum profiles used for high-quality color aluminum windows can generally meet national standards, such as the requirements of relevant national regulations: the wall thickness of aluminum profiles of color aluminum windows should not be less than 1.2mm, and the thickness of oxide film should reach 10 microns. Tempered glass is better than ordinary glass. If considering the safety and durability of doors and windows, hardware accessories made of stainless steel (such as screws, hinges, * * etc.) are better than aluminum accessories, and the pulley is best to choose products made of POM, because such products have higher strength and wear resistance, and are smooth and not easy to break in the process of use. You know, damage to doors and windows usually starts with door and window accessories

second: processing

with good materials, the next step is the processing of doors and windows. As the technical content of doors and windows is not high, and the degree of mechanization is not high at present, most of them still rely on the manual operation of installers, which requires operators to have a good awareness of product quality. It is very important to strengthen the proficiency and product awareness of operators in the production process. The high-quality colored aluminum window has fine processing, smooth tangent and consistent angle (the main frame material is usually 45 degrees or 90 degrees). There should be no obvious gap in the splicing process, with good sealing performance and smooth switching. If the processing is unqualified, there will be sealing problems, not only air and rain leakage, but also the glass will crack and fall off under the action of strong winds and large external forces, resulting in losses of property and even injury to the owner

third: appearance

when choosing door and window products, owners usually pay great attention to the appearance of products and the decorative patterns of glass, and often despise the composite film on the surface of doors and windows. This composite film is formed by coloring the artificial oxide film, which is corrosion-resistant, wear-resistant, high gloss, and also has a certain fire prevention function. Therefore, when choosing aluminum alloy door and window products, they should compare similar products more. Glass technology varies from person to person, and different owners choose according to their preferences

fourth: price

because the price of doors and windows is directly related to the price of aluminum ingots, but in general, the price of doors and windows in a certain period is relatively stable. In general, the price of high-quality doors and windows is 30% higher than that of poor quality doors and windows. Poor quality doors and windows usually use aluminum profiles extruded from recycled aluminum containing a lot of impurities, and some of the aluminum profiles used are only 0.6-0.8 mm thick, Whether from the tensile strength or yield is much lower than the relevant national regulations, this kind of door and window is very unsafe, so the owner must not look down on his own and others' personal safety for the sake of temporary cheapness when purchasing products

fifth: performance

the performance of doors and windows has different emphasis due to the different scope of use, but the following aspects should usually be considered: strength, which is mainly reflected in the material selection of door and window profiles, whether they can withstand ultra-high pressure; Air tightness is mainly reflected in the structure of doors and windows, whether the inner leaf and outer frame of doors and windows are tight, and whether the doors and windows are tight

sixth: reputation

when choosing, we should also pay attention to the reputation and service quality of merchants, which is also very important! Here we can test through three aspects:

first, try to choose manufacturers with good brand reputation. The wood door professional committee of China Wood Circulation Association held a wood door industry conference in Beijing, which selected the top 30 enterprise member units of China wood door through strict research and investigation. These manufacturers are relatively standardized in terms of scale, product quality and service system

II. Check whether the relevant qualification certificates of the manufacturer are complete and true compared with the relevant industry standards

III. before installation, pay attention to the final check by checking the internal materials of the door lock hole. We can't go to the manufacturer to see how to do it. Only considering the well-known and good brand can we guarantee it. We believe that it is reasonable to charge one price for one product

in addition, feel it. As for the process and quality of products, we are unlikely to go to the manufacturer to watch how it is processed. We can only evaluate the process quality of products through simple appearance inspection. Here I'll teach you two things: hand touch and side light. Touch the frame, panel and corner of the door with your hand. It is required to be soft and delicate without scratching. Then stand on the side of the door to face the light to see if there are concave and convex waves on the paint surface of the door. Basically, we can know whether the workmanship is qualified by these two times
