Industry insiders believe that it is the objective requirement of China's energy situation to adopt energy-saving aluminum doors and windows and to carry out aluminum transformation for existing building door and window manufacturers. Therefore, aluminum alloy flat door with excellent comprehensive performance has been widely used. The following small series will introduce how to buy aluminum alloy swing door.

1. The thickness of aluminum alloy flat door
Aluminum alloy profile has the characteristics of high strength, strong corrosion resistance, and is not easy to deform. Why some aluminum alloy doors have not been used for a year before they are in shape? After analysis, under normal use, the aluminum alloy doors appear deformation, which may be caused by the thickness of aluminum alloy profiles used is too thin. It is understood that in the building materials market for consumers to choose aluminum alloy interior doors, profiles have 0.8 mm, 1.0 mm, 1.2 mm and other thicknesses. The aluminum alloy with a thickness of more than 0.5 mm will not deform under normal condition.
2. The choice of aluminum alloy side door depends on the sealing strip
Aluminum alloy door is also characterized by strong decoration. Most of the doors are inlaid with glass. These double glazing have good sound insulation.
Aluminum alloy door experts introduced that the selection of aluminum alloy doors with inlaid glass, especially the products designed with insulating glass, must pay attention to its sealing performance. If the sealing performance is not good, it will lead to dirt in the hollow layer and affect the appearance.
3. Selection of aluminum alloy side door depends on welding process
"The production process of aluminum alloy door is relatively simple, many small manufacturers can produce, but the quality mainly depends on whether the manufacturing process is fine." Aluminum alloy door experts introduced that the welding process reflects the quality of aluminum alloy door. High quality aluminum alloy door, processing fine, welding pay attention to, especially some of the splicing parts are very flat. However, for inferior aluminum alloy doors and windows, the aluminum profile series and specifications are blindly selected, and the processing is rough, and the corner of the door frame cannot be spliced smoothly, and sometimes even large gaps appear.
Consumers should pay special attention to check whether there are welding defects, such as open welding, missing welding and so on. Also see whether the door leaf and door frame are closed tightly, whether the gap is uniform and consistent, and whether the opening is flexible.

4. The selection of aluminum alloy side door depends on the quality of accessories
Aluminum alloy door is usually installed in the bathroom, kitchen and other humid environment, so the quality of hardware hinge, door handle and other accessories is the key to ensure the service life of aluminum alloy door. Many consumers in the purchase of door building materials are very distressed. Because I don't know what kind of door to buy. Many consumers want to buy a cheap, good quality and stronger door.
Consumers should choose the appropriate flat door according to the practical requirements of the door opening scale, opening direction, color pattern and so on. In the process of purchasing, we should pay special attention to check the technical quality: we should pay special attention to check whether there are welding defects, such as open welding, missing welding, not welding and so on. Investigate whether the cooperation between the door leaf and the door frame is dense, whether the gap is uniform and common, whether the opening is sensitive, whether all the joints are dense, the appearance of the door panel should be treated with anti-corrosion treatment, generally spray painting and plastic spraying, the appearance of the paint layer should be free of bubbles, and the color should be uniform. Most doors are embedded with rubber sealing strips on the door frame, and the harsh metal will not be announced when the door is closed Collision sound.
