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, decoration owners must pay attention to the following points when purchasing such products:

 

　　First: Materials

　　

　　When purchasing products, owners often 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 has certain standards for aluminum alloy doors and windows. The thickness, strength and oxide film of the aluminum profiles used for high-quality aluminum alloy doors and windows can generally meet the national standards. If the safety and durability of doors and windows are considered, stainless steel hardware accessories are better than aluminum accessories, and the pulley is best to use POM products, because such products have higher strength and wear resistance, and during use Smooth and not easy to break.

 

　　Second: processing

 

　　With good materials, the next step is the processing of doors and windows. Since the technical content of aluminum alloy doors and windows is not high, and the degree of mechanization is not high at present, most of them still rely on the manual operation of installation workers, which requires operators to have a good awareness of product quality. It is very important to strengthen the operator's proficiency and product awareness in the production process. High-quality aluminum alloy doors and windows, fine processing, smooth tangent, consistent angle (the main frame material is usually 45 degrees or 90 degrees), there should be no obvious gaps during the splicing process, the sealing performance is good, and the switch is smooth.

 

　　Third: performance

 

　　The performance of aluminum alloy doors and windows is different due to the different scope of use, but the following aspects are usually considered: strength, which is mainly reflected in the selection of profiles of aluminum alloy doors and windows, whether it can withstand ultra-high pressure; air tightness It is mainly reflected in the structure of doors and windows, whether the inner fan and outer frame structure of doors and windows are tight, and whether the aluminum alloy outdoor windows are tight and airtight; It mainly depends on the sound insulation effect of insulating glass and other special sound insulation airtight strip structures, as well as the durability of other door and window accessories such as opening and closing force, heat insulation, nylon guide wheel durability, and opening and closing durability.
