The market for aluminum alloy handles is growing, and now many buildings use aluminum alloy handles. Therefore, learning to distinguish the quality of aluminum alloy handles has become a necessary knowledge for consumers.
How to judge the quality of aluminum alloy handles? Whether it is aluminum alloy handle doors (including partition doors) or aluminum alloy windows, decoration owners must pay attention to the following points when choosing such products:
First: Materials used
The main materials used for aluminum alloy handles 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 country has certain standards for aluminum alloy doors and windows. The thickness, strength, and oxide film of aluminum profiles used for high-quality aluminum alloy handles generally meet national standards. For example, relevant national regulations require that the wall thickness of aluminum profiles for aluminum alloy handles should not be less than 1.2mm, and the oxide film thickness should reach 10 micrometers. Tempered glass is better than ordinary glass. When 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 products made of POM material for pulleys because such products have higher strength and wear resistance, and are smooth and not easily damaged during use. You should know that door and window damage usually starts with door and window accessories!
Second: Processing
With good materials, the next step is to process the doors and windows. Due to the low technical content and low level of mechanization of aluminum alloy handles, most of them still rely on manual operation by installation workers, 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, finely processed, with smooth tangents and consistent angles (the main frame material is usually at 45 or 90 degrees), should not show obvious gaps during the splicing process, with good sealing performance and smooth opening and closing. If low-quality aluminum alloy doors and windows, especially aluminum alloy handle products, are not processed properly, they will have sealing problems. Not only will they leak air and rain, but also under the action of strong winds and strong external forces, the glass will crack and fall off, causing damage to property and even personal injury to the owner.
Third: Appearance
When choosing aluminum alloy door and window products, homeowners usually pay great attention to the appearance of the product and the decorative patterns of the glass, but often underestimate the composite film on the surface of aluminum alloy doors and windows. This composite film is formed by artificial oxidation film coloring, which has corrosion resistance, wear resistance, high glossiness, and also has a certain fire resistance function. Therefore, when choosing aluminum alloy handle products, it is necessary to compare similar products more. In the art of glassmaking, it varies from person to person, and different owners choose according to their own preferences.
Fourth: Price
Due to the direct correlation between the price of aluminum alloy handles and the price of aluminum ingots, the overall price of aluminum alloy doors and windows during a certain period is relatively stable. In general, the price of high-quality aluminum alloys is 30% higher than that of low-quality aluminum alloy door and window products. Low quality aluminum alloy handles usually use recycled aluminum extruded aluminum profiles containing a large amount of impurities, some of which have a wall thickness of only 0.6 to 0.8 millimeters, Both in terms of tensile strength and yield strength, they are significantly lower than the relevant national regulations. This type of aluminum alloy handle, especially aluminum alloy handles, is very unsafe. Therefore, when choosing products, owners should not underestimate their own and others' personal safety for a temporary advantage.
Fifth: Performance
The performance of aluminum alloy handles varies depending on the range of use, but usually the following aspects need to be considered: strength, which is mainly reflected in the material selection of aluminum alloy 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 and outer frame structures of doors and windows are tight, and whether aluminum alloy outdoor windows are tight and airtight; Water tightness, mainly assessing whether there is water accumulation or leakage in the aluminum alloy handle; Sound insulation mainly depends on the sound insulation effect of insulating 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, insulation, nylon guide wheel durability, and opening and closing durability.
