With the increasing use of aluminum alloy doors and windows in home decoration, learning to distinguish the quality of aluminum alloy materials has become an essential knowledge for consumers. How to judge the quality of aluminum alloy doors and windows, whether it is aluminum alloy interior doors (including partition doors) or aluminum alloy windows, decoration owners must pay attention to the following points when choosing such products:
Firstly, materials used
The main materials used for aluminum alloy doors and windows generally include three aspects: aluminum profiles, glass, and hardware. When choosing products, homeowners often pay more attention to the thickness of aluminum profiles and glass, but their requirements for hardware are not very high, which is not comprehensive. In fact, the country has certain standards for the requirements of aluminum alloy doors and windows. The aluminum profiles used for high-quality aluminum alloy doors and windows generally meet national standards in terms of thickness, strength, and oxide film. For example, relevant national regulations require that the wall thickness of aluminum profiles for aluminum alloy doors and windows should not be less than 1.2mm, and the oxide film thickness should reach 10 microns. Tempered glass is better than ordinary glass. If considering the safety and durability of doors and windows, stainless steel hardware accessories (such as screws, hinges, handles, etc.) are better than aluminum accessories. It is best to choose POM products for pulleys because these products have higher strength and wear resistance, and are smooth and not easy to break during use. You should know that 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. Due to the low technological content and mechanization level of aluminum alloy doors and windows, most of them still rely on manual operation by installers, which requires operators to have a good awareness of product quality. It is very important to enhance the proficiency and product awareness of operators during the production process. High quality aluminum alloy doors and windows are finely processed, with smooth cutting lines and consistent angles (the main frame material is usually 45 or 90 degrees). There should be no obvious gaps during the splicing process, with good sealing performance and smooth opening and closing. Poor quality aluminum alloy doors and windows, especially aluminum alloy outdoor window products, if processed improperly, will have sealing properties problems. Not only will they leak air and rain, but under strong winds and external forces, the glass will also explode and fall off, causing property damage and even injury to the owners.
Thirdly, appearance
Owners usually pay great attention to the appearance and decorative patterns of the glass when choosing aluminum alloy doors and windows, and often overlook the composite film on the surface of the aluminum alloy doors and windows. This composite film is formed by coloring the artificial oxide film, which has corrosion resistance, wear resistance, high glossiness, and also has a certain degree of fire resistance. Therefore, when choosing aluminum alloy doors and windows, it is necessary to compare similar products more. In terms of glasswork art, it varies from person to person, and different homeowners choose according to their own preferences.
Fourth: Price
Due to the direct correlation between the price of aluminum alloy doors and windows and the price of aluminum ingots, the price of aluminum alloy doors and windows is generally relatively stable during a certain period. In general, the price of high-quality aluminum alloy doors and windows is 30% higher than that of low-quality aluminum alloy doors and windows. Low quality aluminum alloy doors and windows usually use recycled aluminum extruded profiles containing a large amount of impurities. Some of the aluminum profiles used have a wall thickness of only 0.6-0.8 millimeters, which is much lower than the relevant national regulations in terms of tensile strength and yield strength. These types of aluminum alloy doors and windows, especially aluminum alloy outdoor windows, are very unsafe. Therefore, when choosing products, owners should not underestimate their own and others' personal safety for the sake of temporary cheapness.
Fifth: Performance
The performance of aluminum alloy doors and windows varies depending on the scope of use, but usually the following aspects need to be considered: strength, which is mainly reflected in the selection of materials for the profiles of aluminum alloy doors and windows, whether they can withstand ultra-high pressure; Airtightness is mainly reflected in the structure of doors and windows, whether the inner and outer frames of doors and windows are tight, and whether aluminum alloy outdoor windows are tight and not breathable; Water tightness mainly assesses whether there is water accumulation or leakage in aluminum alloy doors and windows; Soundproofing mainly depends on the sound insulation effect of insulated glass and other special sound insulation and airtight strip structures, as well as the durability of other door and window accessories such as opening and closing force, heat insulation, nylon guide wheel durability, and opening and closing durability.
