We all know that the aluminum alloy folding door has many advantages, such as waterproof, sound insulation, corrosion resistance, good heat insulation, no deformation, no fading, etc. it integrates artistry and practicability, and is very popular in the sales market of doors and windows. So how to choose aluminum alloy folding door, how to look at the quality of the knowledge you can learn Oh.
First of all, aluminum alloy profiles have the characteristics of high strength, strong corrosion resistance, and not easy to deform. However, the aluminum alloy folding door of some friends' home has not been used for a year. After analysis, under normal use, the aluminum alloy folding door deforms, which may be caused by the thickness of the aluminum alloy profile used.
At present, aluminum alloy folding doors for consumers to choose in the door and window market have various thicknesses of 0.8 mm, 1.0 mm, 1.2, 1.4, 1.6 mm, 2.0 mm, etc. Among them, the strength of aluminum alloy folding door above 1.2mm is better, and it will not deform in 5 ~ 8 years under normal use. But some small manufacturers in order to make huge profits and cut corners, and even use the thickness of only 0.6 mm aluminum alloy profiles made of bathroom doors. Because the thickness of the aluminum alloy folding door is too thin, it will deform under the action of gravity. The thickness of profile directly determines the advantages and disadvantages of aluminum alloy folding door. Therefore, when you choose aluminum alloy folding door, do not choose aluminum alloy folding door with too thin profile for the sake of low price.
Secondly, the aluminum alloy folding door also has a feature of strong decoration. Most of the aluminum doors and windows on the market are inlaid with various colors. These glass have single layer, also have stereo sense strong, sound insulation effect is good double layer insulating glass. Choose the aluminum alloy folding door with inlaid glass, especially the products with insulating glass design, we 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. Aluminum alloy doors and windows brand manufacturers use high-quality sealant strip, with advanced hot pressing sealing technology for all-round sealing treatment, which can effectively prevent dust and water, and has outstanding sound insulation effect.
To check the sealing performance of the glass partition of the aluminum alloy folding 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.
Aluminum alloy folding door production process is relatively simple, many small manufacturers can produce, but the quality is mainly in the production process is fine. The welding process reflects the quality of aluminum alloy folding door. High quality aluminum alloy folding door, fine processing, welding pay attention to, especially some of the splicing parts are very flat. Aluminum alloy door frame, and sometimes the poor quality of the door can not be processed.
For the welding process, 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. After checking the welding process of the aluminum alloy folding door, the consumer should carefully check whether the paint surface of the aluminum alloy folding door is bright in color and clear in texture, and pay attention to that the paint surface shall not have obvious scratch, bubble and other defects.
