Decoration owners must pay attention to the following points when purchasing aluminum alloy doors and windows products:
The main materials used for aluminum alloy doors and windows generally include three aspects: aluminum profiles, glass and hardware. When the owners purchase products, they 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 state has certain standards for aluminum alloy doors and windows. The thickness, strength and oxide film of high quality aluminum alloy doors and windows can generally meet the national standards. The toughened glass is better than ordinary glass. If the safety and durability of doors and windows are considered, stainless steel hardware accessories (such as screws, hinges, handle, etc.) are better than aluminum parts, and POM material products are the best choice for pulleys, because such products have higher strength and wear resistance, and they are smooth in use and not easy to be damaged. To know, the door and window damage is usually from the door and window accessories yo!
With good materials, the next step is the processing of aluminum alloy doors and windows. Because the technical content of aluminum alloy 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 aluminum alloy doors and windows, fine processing, smooth tangent, consistent angle (the main frame material is usually 45 degrees or 90 degrees), in the splicing process should not appear more obvious gap, good sealing performance, smooth switch. Poor quality aluminum alloy doors and windows, especially aluminum alloy outdoor products, if the processing is not qualified, there will be sealing property problems, not only air leakage and rain leakage, but also under the action of strong wind and large external force, the glass will burst and fall off, thus causing loss of property and even injury to the owner.
The owners usually pay attention to the appearance of the products and the decorative patterns of the glass when purchasing the aluminum alloy doors and windows products, but often despise the composite film on the surface of the aluminum alloy doors and windows. This composite film is formed by artificial oxidation film coloring, which has corrosion resistance, wear resistance, high gloss, and also has certain fire prevention function. Therefore, when purchasing aluminum alloy doors and windows products, it is necessary to compare similar products 。 In the art of glass work, different owners choose according to their own preferences.
As the price of aluminum alloy doors and windows is directly related to the price of aluminum ingot, but generally, the price of aluminum alloy doors and windows in a certain period is relatively stable. In general, the price of high-quality aluminum alloy doors and windows is 30% higher than that of inferior aluminum alloy doors and windows products. The aluminum profiles used for poor quality aluminum alloy doors and windows are usually recycled aluminum extruded profiles containing a lot of impurities Some wall thickness is only 0.6-0.8 mm, both in terms of tensile strength and yield are greatly lower than the relevant provisions of the state, so owners in the purchase of products must not be cheap and despise the personal safety of themselves and others.
The performance of aluminum alloy doors and windows has different emphasis due to the different scope of use, but the following aspects should be considered: strength, which is mainly reflected in the selection of aluminum alloy door and window profile materials, whether it can withstand ultra-high pressure; air tightness, mainly reflected in the door and window structure, whether the inner leaf and outer frame structure of the door and window are tight, mainly to assess whether there is water accumulation in the aluminum alloy doors and windows Leakage phenomenon; sound insulation, which mainly depends on the sound insulation effect of insulating glass and other special sound insulation and air tight strip structure, as well as the durability of opening and closing force, heat insulation, nylon guide wheel durability, opening and locking durability and other accessories.
