ã€China Aluminum Industry Network】 1. Materials The main materials for aluminum 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, and to the hardware. The request is not very high. 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 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 POM materials. Because such products have higher strength and wear resistance, they are smooth during use and are not easily damaged.
Second, processing with a good material, 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 important to enhance the proficiency of the operators and product awareness during the production process. High-quality aluminum alloy doors and windows, fine processing, tangent smooth, consistent 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 formed, with corrosion resistance , Wear resistance, high gloss, but also has 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, the price As the price of aluminum alloy doors and windows has a direct correlation with the level of aluminum ingot prices, but in general, the price of aluminum alloy doors and windows in a certain period is relatively stable, in general, the price of high quality aluminum alloy Inferior quality aluminum alloy door and window products are 30% higher. Inferior quality aluminum alloy doors and windows are usually made of recycled aluminum extruded aluminum containing a lot of impurities. The used aluminum profiles have a wall thickness of only 0.6-0.8 mm, both in terms of tensile strength and yielding. Degrees are 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 take any cheap measures and despise the personal safety of themselves and others.
