㎡Judging the advantages and disadvantages of aluminum alloy doors and windows, whether it is aluminum alloy interior doors (including thermal break bridge profiles) or aluminum-wood composite profiles gold windows, you must pay attention to the following points when purchasing such products:

First: materials

The main materials generally include three aspects: aluminum profiles, glass, hardware, when the owner purchases products, they tend to 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's requirements for aluminum alloy doors and windows are certain. The aluminum profiles used for high-quality aluminum alloy doors and windows, the thickness, strength and oxide film can generally meet the national standards, such as the relevant national requirements: aluminum alloy doors and windows aluminum profile wall thickness should be no less than 1.2mm, oxide film The thickness should be 10 microns. While tempered glass is better than ordinary glass, if the safety and durability of doors and windows can be considered, stainless steel hardware accessories (such as screws, hinges, handles, etc.) are better than aluminum fittings, and the pulleys are best to use POM products. Because of the higher strength and wear resistance of these products, the use process is smooth and not easy to break. Be aware that door and window damage is usually the beginning of the door and window accessories!

Second: processing

With good materials, the next step is the processing of doors and windows. Due to the low technical content of aluminum alloy doors and windows, the degree of mechanization is currently not high, and most of them 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 and product awareness of the operator during the production process. High-quality aluminum alloy doors and windows, fine processing, smooth tangent, uniform angle (the main frame material is usually 45 degrees or 90 degrees), there should be no obvious gaps in the splicing process, the sealing performance is good, the switch is smooth. Inferior aluminum alloy doors and windows, especially aluminum alloy outdoor window products, if processed unqualified, there will be sealing problems, not only leakage of wind and rain, but also under the action of strong wind and large external force, the glass will burst and fall off, thus giving The owner caused damage to property and even injury.

Third: appearance

The owner purchases aluminum alloy door and window products, usually pays attention to the appearance of the product and the decorative pattern of the glass, and often scorns the composite film on the surface of the aluminum alloy door and window. The composite film is formed by the artificial oxide film coloring, which has corrosion resistance and wear resistance. Loss, high gloss, and also have a certain degree of fire protection, so when buying aluminum alloy doors and windows products, compare more similar products. The art of glasswork varies from person to person, and different owners choose according to their own preferences.
