Selection method of high quality aluminum alloy
First, the material
 
The Mingtai aluminum door and window materials generally consist of three aspects: aluminum, glass, metal parts, and the owner often pay more attention to the thickness of aluminum and glass when purchasing products, and the hardware requirements are not very high, it is not comprehensive. In fact, the state of the aluminum alloy doors and windows requires certain standards. aluminum alloy doors and windows are made of high-quality aluminum profiles. The thickness and strength of the film generally conform to national standards. For example, the relevant national regulations: aluminum alloy doors and windows, aluminum alloy wall thickness should be no less than 1.2mm, the thickness of the oxide film should reach 10 microns. Although glass is better than ordinary glass, if you consider the safety and durability of doors and windows,
 
Second, processing
 
There are good materials; the next step is the processing of doors and windows. Because the technical content of aluminum alloy doors and windows is not high, the degree of mechanization is not high, and most of them rely on the installation workers, manual operation, which requires the operator to have a better understanding of product quality. It is important to enhance operator proficiency and product awareness during the production process. High-quality aluminum alloy doors and windows, fine processing, smooth tangent, the same point of view (the main frame material is usually 45 degrees or 90 degrees), there should be no obvious gap during the stitching process, the sealing performance is good, the switch is smooth. Inferior aluminum alloy doors and windows, especially aluminum alloy outdoor window products, if the processing is not qualified, it will lead to sealing problems.
 
Third, the appearance
 
Owners buy aluminum alloy doors and windows products, usually pay attention to the appearance and products of glass decorative patterns, often degrading the surface of composite film aluminum alloy doors and windows and composite film is made of artificial coloring, corrosion resistance, wear resistance, high gloss. At the same time, it also has a certain fire protection function, so when purchasing aluminum alloy doors and windows products, it can make multiple comparisons of similar products. In the glass industry, it varies from person to person depending on their preferences and different owners.
 
Fourth, the price
 
Because the price of aluminum alloy doors and windows is directly related to the aluminum price level, in general, the performance price of aluminum alloy doors and windows is relatively stable. Generally speaking, the price of high-quality aluminum alloy is 30% higher than that of inferior aluminum alloy doors and windows. Inferior aluminum alloy doors and windows are usually made of aluminum extrusion aluminum containing a large amount of impurities, part of the aluminum wall thickness of 0.6-0.8 mm, whether the tensile strength or yield strength is significantly lower than the national regulations, such aluminum alloy doors and windows, especially Aluminum outdoor windows are not safe, so owners should not cheaply replace themselves and others when purchasing products.
