we often see various customized workshops for aluminum alloy doors and windows with small facades, but can the products produced by the small workshops really meet the requirements we expect? Let's not talk about energy conservation. Is it corrosion-resistant? Is it insulated? Is it waterproof and moisture-proof? Sound insulation? Resistance to wind pressure? Is it safe in the end? The quality of family doors and windows is related to their own safety. Once there is a problem with doors and windows, it is not only a matter of individual families, but also may endanger the life safety of pedestrians downstairs. However, how to choose? Now, Katy's door and window editor will introduce it to you

first look at the materials of doors and windows: the thickness, strength and oxide film of high-quality aluminum alloy doors and windows are in line with the relevant national standards. The wall thickness should be more than 1.2mm, and the oxide film thickness should reach 10 microns. If the product exceeds the national standard or even reaches the Dezhou standard, it is certainly the best choice

second, look at the processing of doors and windows: high-quality aluminum alloy doors and windows, with fine processing, exquisite installation, good sealing performance and free switching. The materials and specifications of inferior aluminum alloy doors and windows are not up to the standard, and the processing is uneven. The sealing performance is poor. Not only does it leak air and rain, but also it is easy to crack the glass in the case of strong wind and excessive external force, causing the glass to scrape or fall

third, look at the appearance of doors and windows: the appearance of doors and windows is also a key link. There is an artificial oxide film on the surface of aluminum alloy doors and windows and coloring to form a composite film. This composite film is not only corrosion-resistant and wear-resistant, but also has a certain fire protection function. The gloss is very high. When selecting, try to compare as much as possible, try to choose the products of regular aluminum alloy door and window manufacturers, and select the products with precise and accurate processing and assembly, light and flexible opening, and no noise, Products with elegant decorative effect

fourth, look at the price of doors and windows: in general, the price of high-quality aluminum alloy doors and windows is higher than that of low-quality aluminum alloy doors and windows because of the high production cost. The tensile strength and yield strength of some aluminum alloy doors and windows made of aluminum profiles are much lower than the relevant national standards, so it is very unsafe to use them. We must not ignore our own safety factors because we are greedy for a temporary bargain

fifth, look at the performance of doors and windows: aluminum alloy doors and windows usually assess the following main performance, strength, air tightness, water tightness, opening and closing force, noise, heat insulation, nylon guide wheel durability, opening and locking durability and other factors

every product of Cartier doors and windows will adhere to the details, grasp the quality, and formulate detailed quality management standards in every link. Establish a quality assurance system independent of production management. Detailed and controllable management standards have been formulated from product design, process flow, workshop production, transportation and sale
