Editor: liefan, September 8, 2019 11:00:02

Aluminum alloy doors and windows are favored by consumers because of their rich styles, strong corrosion resistance, durability and affordable price. In the purchase of aluminum alloy door, if the thickness of aluminum alloy door profile is not up to standard and the production process is not up to standard, it can not maintain its beauty for a long time, and even affect the use of the door
Here are four points that should be paid attention to when purchasing aluminum alloy doors
1. Profile thickness
The 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 to go? According to liefan's analysis, under normal use, the deformation of aluminum alloy door may be caused by the thickness of aluminum alloy profile used is too thin.
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. If the profile thickness is not enough, it is easy to cause the deformation of aluminum alloy door.
It is suggested that the thickness of profile directly determines the quality of aluminum alloy door. When consumers choose aluminum alloy door, do not covet cheap and choose aluminum alloy door with too thin profile.
2. Glass 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 doors and windows 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. Brand products use high-quality sealant strip, with advanced hot pressing sealing technology to ensure all-round sealing treatment, which can effectively prevent dust and water, and has outstanding sound insulation effect.
Tips: to check the sealing performance of the glass partition layer of the aluminum alloy door, in addition to checking whether the glass glue coating on the front is tight, it is also necessary to check whether the sealing strip on the glass back of the door is flat, and there is no curling or sloughing.
3. Look at the craft
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.
Tips: after checking the welding process of aluminum alloy door, consumers should carefully check whether the paint surface of the product is bright in color and clear in texture, and pay attention to no obvious scratch, bubble and other defects on the paint surface.
4. Quality of aluminum alloy accessories
Aluminum alloy door handle is the key to ensure the quality of the door handle in the kitchen.
  
Tips: in addition to checking whether the hinge uses materials that are not easy to rust, it is better to choose stainless steel door locks, handles and other hardware to prevent rust and affect the use.
