First: materials
The main materials for 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. This is incomplete. . In fact, the country has certain standards for the requirements of color aluminum windows. The aluminum profiles used in high-quality aluminum windows are generally able to meet the national standards for their thickness, strength and oxide film. For example, the relevant national regulations require that the wall thickness of aluminum profiles of color aluminum windows should not be less than 1.2 mm, and the 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, **, etc.) are better than aluminum accessories, and the best choice of pulleys is POM material. Products, because such products have higher strength and wear resistance, smooth during use, not easy to damage. You know, the door and window damage is usually started from the door and window accessories!
Second: processing
With good materials, the next step is the processing of doors and windows. As the technical content of doors and windows is not high, the degree of mechanization is not high at present, and most of them rely on the manual operation of the installation workers, which requires operators 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 color aluminum windows, fine processing, smooth tangent line, the same angle (main frame material is usually 45 degrees or 90 degrees), in the splicing process should not appear more obvious gaps, sealing performance, smooth switch. If the processing is unqualified, there will be sealing problems. Not only air leakage but also strong winds and large external forces will cause the glass to burst and fall off, causing the property owners to lose their property or even hurt them.
Third: Appearance
Owners choose doors and windows products, usually pay attention to the appearance of the product and the decorative pattern of the glass, but often despise the composite film on the surface of the door and window, this composite film is formed by artificial oxide film coloring, with corrosion resistance, wear resistance, high gloss Degree, 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 glass process varies from person to person, and different owners choose according to their preferences.
Fourth: Price
Since the price of doors and windows is directly related to the price of aluminum ingots, the prices of doors and windows in a certain period are relatively stable. In general, the price of high-quality doors and windows is 30% higher than that of inferior doors and windows. Inferior doors and windows usually use recycled aluminium extrusions containing large amounts of impurities. The aluminium profiles used have wall thicknesses of only 0.6-0.8 mm. Both the tensile strength and the yield are significantly lower than the relevant national regulations. It's not safe, so owners don't want to pay attention to the personal safety of themselves and others when they choose products.
