The market for aluminum alloy doors and windows is getting bigger and bigger. Nowadays, many buildings use aluminum alloy doors and windows, so learning to judge the quality of aluminum alloy materials has become a necessary knowledge for consumers.
How to judge the advantages and disadvantages of aluminum alloy doors and windows? Whether it is aluminum alloy interior doors (including partition doors) or aluminum alloy windows, the decoration owner must pay attention to the following points when purchasing such products:
Front: Material aluminum alloy doors and windows of the main materials generally include three aspects: aluminum, glass, hardware, the owners in the purchase of products, often pay more attention to the thickness of aluminum and glass, and the requirements of the hardware is not very Gao, this is incomplete. In fact, the country has a certain standard for aluminum alloy doors and windows. High-quality aluminum alloy doors and windows used in aluminum, its thickness, strength and oxide film can generally meet the national standards, such as the relevant national regulations require: aluminum alloy doors and windows of aluminum wall thickness should not be less than 1.2mm, oxide film The thickness should reach 10 microns. Tempered glass is better than ordinary glass. If the security of doors and windows and durability can be considered, stainless steel hardware accessories (such as screws, hinges, handles, etc.) are better than aluminum accessories, and pulleys are better choice of products using POM materials. Because such products have higher strength and wear resistance, they are smooth during use and are not easily damaged. You know, the door and window damage is usually started from the door and window accessories!
Second: With good materials for processing, the next step is the processing of doors and windows. As the technical content of aluminum alloy doors and windows is not high, the degree of mechanization is not high at present, most of them also rely on the manual operation of the installation workers, which requires the operator to have a good sense of product quality. It is very important to enhance the proficiency and product awareness of operators in the production process. High-quality aluminum alloy doors and windows, fine processing, smooth tangent, the same angle (main frame material is usually 45 degrees or 90 degrees), in the splicing process should not appear more obvious gaps, good sealing performance, smooth switch. Inferior quality aluminum alloy doors and windows, especially aluminum alloy outdoor window products, will cause sealing problems if they are not processed properly. Not only will air leakage leak, but under strong winds and large external forces, the glass will burst and fall off. The owner caused a loss of property and even hurt the person.
Third: The appearance of the owners to buy aluminum alloy doors and windows products, usually pay attention to the appearance of the product and glass decorative patterns, and often despise the aluminum alloy doors and windows surface of the composite film, this composite film is artificial oxide film coloring, with resistance Corrosion, wear resistance, high gloss, but also have a certain degree of fire protection, so when you buy aluminum alloy doors and windows products to compare more similar products. The art of glasswork varies from person to person, and different owners choose according to their own preferences.
Fourth: prices As the price of aluminum alloy doors and windows has a direct correlation with the price of aluminum ingots, but in general, the prices of aluminum alloy doors and windows in a certain period are relatively stable. Under normal circumstances, the price of high-quality aluminum alloys Than poor quality aluminum alloy doors and windows products to be 30% higher, poor quality aluminum alloy doors and windows usually use recycled aluminum extruded aluminum containing a lot of impurities, the aluminum profiles used are only 0.6-0.8 mm in thickness, whether from the tensile strength or The degree of yield is much lower than the national regulations. Such aluminum alloy doors and windows, especially aluminum alloy outdoor windows, are not safe. Therefore, when purchasing products, the owners must not look cheap and despise the personal safety of themselves and others.
Fifth: The performance of aluminum alloy doors and windows due to the use of different scope and focus is different, but usually consider the following aspects: Strength, which is mainly reflected in the aluminum alloy doors and windows of the profile of the choice of materials, he can withstand super High pressure; air tightness, mainly reflected in the structure of doors and windows, doors and windows of the internal fan and frame structure is tight, aluminum alloy outdoor window is tight and airtight; watertight, the main assessment of aluminum alloy doors and windows exist water, leakage phenomenon; Sound insulation, which mainly depends on the sound insulation effect of insulating glass and other special sound-proof airtight structure and the durability of other door and window accessories such as opening and closing force, heat insulation, durability of nylon guide wheel, and durability of opening and closing lock.
