What is a trackless sliding door? The sliding door itself is pushed and pulled by the track. If there is no track, it can not be used normally. However, the trackless sliding door is not completely trackless. It is the same reason that there is no fish in the fish flavored meat. Only on the ground, there is no need to install tracks, and the real tracks are all on the ground. Therefore, the door is completely suspended above, so there is still no essential change in principle. It still relies on its own pulley to move smoothly on the track. The unique structure of trackless sliding door also has certain particularity during installation. The most important point is to ensure the strength of the top rail. Because, like ordinary sliding doors, all the weight is pressed on the ground rail, and the ground rail is supported by the ground, so there will be no deformation.

However, when the trackless structure is made, the weight of the door is all on the lifting rail. Especially when the door is wide, it is easier to bend the rail. Therefore, it needs to be made of thicker profiles and ensure the strength of installation. If the common process is also installed, problems may occur in a short time. However, the trackless sliding door does have a very obvious advantage, that is, it will not cause any damage to the ground. Because the area of our rooms is limited, we all hope that they can be more spacious and transparent when decorating. With such an additional track, it is visually separated and inconvenient to walk. In particular, families with old people or children may stumble over this threshold. In addition, long-term trampling will also cause dirt in the ground rail, which is extremely inconvenient to clean. Therefore, as long as the installation quality can be ensured, it is indeed a good idea to choose this kind of hanging cabinet structure. The trackless sliding door is generally also called the hanging door or the hanging rail sliding door. The trackless sliding door looks like it has no track, but it actually has a track. Compared with the ground rail sliding door, the trackless sliding door has the advantage of convenient cleaning. However, since the pulley of the trackless sliding door replaces the ground rail, its sealing and stability are slightly weaker than that of the ground rail sliding door.

Because there is no ground rail, the trackless sliding door relies on the upper rail and the lower locator to move, so there is no need to worry about the elderly and children tripping over the ground rail; Trackless sliding doors are often used in the indoor environment of kitchen and study, which is a good choice for people who are sensitive to sound.
In addition to the poor sealing and stability of trackless aluminum alloy sliding doors, there are also some problems, that is, with the increase of service life, the door body will inevitably sink, but generally it will not affect normal use. For trackless sliding doors, the lifting rails and pulleys bear the weight of the whole sliding door. In addition to daily opening and closing, it is inevitable that there will be wear problems for a long time, and then daily maintenance and care are required to make the trackless sliding door continue to be used for a long time.

The simple and atmospheric shape of the trackless sliding door gives people an elegant atmosphere, and the symmetrical design also conforms to the traditional concept of the Chinese people. Therefore, many people like to install trackless sliding doors in their homes, whether for warmth and comfort or for matching with decoration style. The advantages of trackless aluminum alloy sliding doors are also obvious.
1. The trackless sliding door actually has a track, but its track is on the top of the door, so it will not cause any damage to the ground during use, nor will it jam or generate noise because the entire trackless sliding door track is pressed on the ground.
2. The trackless sliding door does not set tracks on the ground, so when the door is pushed open, the overall space looks wider and it is more convenient to walk; Especially families with old people or children.
3. Stepping on the sliding door track for a long time will cause accumulation of viscera on the ground rail, which is extremely inconvenient to clean. Therefore, as long as the installation quality can be guaranteed, it is a good idea to choose this trackless aluminum alloy sliding door.

So, what are the precautions when using trackless sliding doors? First, when using the trackless sliding door, do not hang heavy objects on the door leaf or avoid collision or scratch with sharp objects. When opening or closing the door leaf, do not force too hard or open the door at too large an angle to avoid damaging the trackless sliding door. Secondly, when the trackless aluminum alloy sliding door is used, the top needs to be reinforced to prevent potential safety hazards caused by improper use. Then, when opening the trackless sliding door or turning the door lock handle, do not use too much force, which will reduce the service life of the trackless sliding door lock. At the same time, pay attention to the looseness of the upper screws. If looseness is found, it must be tightened to prevent accidents during use.
