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. Among them, the aluminum alloy door with the thickness of more than 1.0 mm has better strength and will not deform for 5-8 years under the premise of normal use.
2. The choice of aluminum alloy side door depends on the sealing strip
Aluminum alloy door is also characterized by strong decoration. Most aluminum doors are inlaid with art glass of various colors. These glass have single layer, also have stereo sense strong, sound insulation effect is good double layer insulating glass.
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. Attention should be paid to the defects in the welding process, such as missing welding. When the door frame is sprayed with paint evenly, whether the paint on the door frame is sensitive to paint and there should be no crack on the door frame Collision sound.
