First of all, it depends on the information of the
aluminum profile used. The aluminum alloy profile used for the good quality partition bridge aluminum alloy doors and windows must meet the relevant national standards in terms of thickness, strength and oxide film. The wall thickness of the broken bridge aluminum alloy doors and windows It should be above 1.2 mm, at least 108 Newtons per square millimeter of yield strength, 157 Newtons per square millimeter of tensile strength, and oxide film thickness of 10 microns. For those aluminum alloy doors and windows that do not meet the above standards, 100% of them are inferior in quality, please choose carefully. Then, the exquisite level and professional skills of aluminum door and window processing manufacturers for aluminum profile processing are points worthy of consideration for consumers. Good aluminum alloy profiles are paired with good aluminum alloy door and window processing manufacturers, professional production equipment workers, A good horse with a good saddle! The aluminum alloy doors and windows are processed exquisitely, with professional skills and equipment, and the ability to make it have good sealing function and open and close. According to the field of application of industrial aluminum, industrial aluminum profiles refer to all aluminum profiles except for architectural doors and windows, curtain walls, indoor and outdoor decoration and aluminum profiles for architectural structures. On the contrary, technical personnel blindly choose aluminum series and standards, cut corners in processing, and even use sawing to replace milling. The equipment constructors do not perform equipment as needed, so that the aluminum material produced has poor sealing function, and the switch is not smooth and cannot be effective. The ground blocks wind and rain. Strictly, it may also cause the glass to burst. If you encounter strong winds and external forces, you can simply push or pull some of the glass or the glass will be scraped or knocked off. The damage to the doors and windows is small, hurting family members or passing pedestrians, and you are worried. what! Finally, when it comes to the quotations that consumers are all over the heart of comparison, under normal circumstances, good quality doors and windows are high in production costs, and the quotation judgment is about 30% higher than that of unqualified aluminum alloy doors and windows. According to the field of application of industrial aluminum profile, industrial aluminum profiles refer to all aluminum profiles except for architectural doors and windows, curtain walls, indoor and outdoor decoration and aluminum profiles for architectural structures. For some aluminum alloy doors and windows produced from aluminum with a thickness of only 0.6-0.8 mm, the tensile strength and yield strength are far lower than the relevant national standards, and the use is very unsafe. Therefore, as the saying goes, you get what you pay for; consumers must choose good profiles and must not be greedy for a little cheap. Wall thickness of aluminum alloy doors and windows: Usually, the products are installed, and most aluminum processing plants choose products with high yield, that is, products with relatively thin wall thickness to reduce the cost. National standard: The thickness of the profile should be greater than or equal to 1.4mm. Insulation strips: Insulation strips make the most important part of broken aluminum doors and windows. PA66 nylon must be used. This is the national standard. However, many manufacturers in the current decoration market use cheap PVC plastic insulation strips, which will strictly affect aluminum. The service life of alloy doors and windows products. According to the field of application of industrial aluminum profile, industrial aluminum profiles refer to all aluminum profiles except for architectural doors and windows, curtain walls, indoor and outdoor decoration and aluminum profiles for architectural structures. Try to choose the original products from the original factory as much as possible, not self-painted products with secondary spraying. Those who may allow customers to randomly select the color of the profile are mostly self-painted products with secondary spraying. The quality of the products is helpless to compare with the original original products. In the real life, we know too little about the professional common sense and some professional terminology of thermally insulated and broken aluminum alloy doors and windows. Knowing some of its basic functions and advantages, we seem to have a proper impression of it. Right! At the same time, in the process of exchanging with many customers, we found that some customers have many blind spots and do not know why they are at a loss as to how to select and distinguish the quality of aluminum doors and windows.
