　　First: Materials 　　 The
　　main materials used for doors and windows generally include three aspects: outer frame profiles, glass, and hardware. Owners often pay more attention to the thickness of profiles and glass when purchasing products, but the requirements for hardware are not very high, which is not comprehensive. In fact, the country has certain standards for doors and windows. The thickness, strength and oxide film of the profiles used for high-quality doors and windows generally meet the national standards. Tempered glass is better than ordinary glass. If you consider the safety and durability of doors and windows, stainless steel hardware accessories (such as screws, hinges, etc.) are better than aluminum accessories. You must know that door and window damage usually starts from door and window accessories Yo!
　　Second: Processing
　　With good materials, the next step is the processing of doors and windows. Because 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 good product quality awareness. It is very important to strengthen the proficiency of operators and product awareness in the production process. High-quality doors and windows have fine processing, smooth tangent lines and consistent angles (the main frame material is usually 45 degrees or 90 degrees), there should be no obvious gaps in the splicing process, good sealing performance, and smooth opening and closing. If the processing is unqualified, there will be problems with sealing properties, not only leakage of wind and rain, but also the phenomenon of glass explosion and falling under the action of strong wind and large external force, which will cause loss of property and even injury to the owner.
　　Third: Appearance When
　　buying door and window products, owners usually pay attention to the appearance of the product and the decorative pattern of the glass, but often underestimate the composite film on the surface of the door and window. This composite film is formed by artificial oxide film coloring, which is corrosion-resistant and wear-resistant. It has high gloss, and also has a certain fire protection function, so compare similar products when buying doors and windows. The glass process varies from person to person, and different owners choose according to their own preferences.
　　Fourth: Price
　　Since the price of doors and windows is directly related to the price of materials on the market, the prices of doors and windows in a certain period of time are relatively stable. Under normal circumstances, the price of high-quality doors and windows is 30% higher than that of inferior products. , Inferior doors and windows are usually extruded or recast with a lot of impurities, both in terms of tensile strength and yield are greatly reduced. Such doors and windows are very unsafe, so owners must not try to be cheap when buying products. And underestimated the personal safety of oneself and others.
　　Fifth: Performance The performance of
　　doors and windows is different due to the different scopes of use, but the following aspects are usually considered: strength, which is mainly reflected in the selection of materials for doors and windows, whether it can withstand ultra-high pressure; air tight The performance is mainly reflected in the door and window structure, whether the inner leaf and outer frame structure of the door and window are tight, and whether the doors and windows are tight.
　　Sixth: Reputation
　　When choosing, we should also pay attention to the reputation of the merchant and the quality of service. This is also very important! Here we can check in three aspects:
　　First, try to choose a manufacturer with a good brand reputation.
　　2. Pass the inspection to see whether the relevant qualification certification of the manufacturer is complete and true compared to the relevant industry standards.
　　3. 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 by considering the brand with high reputation and good reputation can we guarantee it. We believe that one price for one product makes sense.




　　In addition, feel the touch. As for the process and quality of the product, we are unlikely to go to the manufacturer to stare at how it is processed. We can only evaluate the process quality of the product through simple visual inspection methods. Here are two things to teach you: touch and look s
