With the advent of autumn decoration season, you guys are beginning to have a headache about the purchase of various building materials. How to purchase doors and windows has always been a major problem in many industries. How about choosing good doors and windows? The author presents you with a classic and practical door and window shopping strategy, hoping to bring you help.

First: Materials

The main materials used for doors and windows generally include three aspects: aluminum profiles, glass and hardware. When choosing products, owners often pay more attention to the thickness of aluminum profiles and glass, but the requirements for hardware are not very high, which is not comprehensive. In fact, the national requirements for color aluminum windows have certain standards. The thickness, strength and oxide film of aluminum profile used for high-quality color aluminum window can generally meet the national standards, such as the relevant national requirements: the wall thickness of aluminum profile of color aluminum window should be no less than 1.2mm, and the thickness of oxide film should be 10 μ M. The toughened glass is better than ordinary glass. If the safety and durability of doors and windows are considered, the hardware fittings made of stainless steel are better than that of aluminum parts, and POM material products are better for pulleys, because such products have higher strength and wear resistance, and they are smooth and not easy to be damaged. You know, door and window damage is usually from the door and window accessories!

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, the degree of mechanization is not high, most of them still rely on the manual operation of installation workers, which requires operators to have good product quality awareness. In the production process, it is very important to enhance the proficiency of operators and product awareness. High quality color aluminum window, fine processing, smooth tangent, consistent angle, in the splicing process should not appear more obvious gap, good sealing performance, smooth switch. If the processing is not qualified, there will be sealing property problems, not only air and rain leakage, but also under the action of strong wind and large external force, the glass will burst and fall off, which will cause property loss and even injury to the owner.

Third, appearance

The owners usually pay attention to the appearance of the products and the decorative patterns of the glass when purchasing the door and window products. However, they often despise the composite film on the surface of the doors and windows. This kind of composite film is formed by artificial oxidation film coloring, which has corrosion resistance, wear resistance, high gloss, and certain fire prevention function. Therefore, when purchasing aluminum alloy doors and windows products, it is necessary to compare similar products. In the glass process, different owners choose according to their own preferences.

Fourth: price

As the price of doors and windows is directly related to the price of aluminum ingot, 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. Aluminum profiles containing a large number of impurities are usually used for poor quality doors and windows. Some of the aluminum profiles used are only 0.6-0.8 mm in wall thickness From the tensile strength or yield are greatly lower than the relevant provisions of the state, this kind of doors and windows are very unsafe, so owners in the purchase of products must not seek temporary cheap and despise the personal safety of themselves and others.

Fifth: performance

The performance of doors and windows depends on the scope of use, but the following aspects should be considered: strength, which is mainly reflected in the selection of materials for door and window profiles, whether it can withstand ultra-high pressure; air tightness, mainly reflected in the structure of doors and windows, whether the inner leaf and outer frame structure of doors and windows are tight, whether the doors and windows are tight.
