Is the sliding door better on the track or on the track? Why?

As we all know, sliding door is a common door. It has many types. According to the different tracks, it can be divided into upper track and lower track. We can choose according to our own preferences and decoration needs. By comparing the advantages and disadvantages of the upper rail sliding door and the lower rail sliding door, we can see that both of them open and close the door by pushing and pulling. The sliding door with lower guide rail has a guide rail at the upper part and a ground rail at the lower part. There is a hidden wheel under the door, and the gravity is concentrated under the door, while the gravity of the track door is concentrated on the door. Compared with the sliding door of the upper track, the biggest disadvantage of the sliding door of the lower track is that the door slot of the ground track is easy to accumulate water and hide dirt, which is very troublesome to clean up.

There is no threshold on the upper rail, so don't worry at all. Cleaning is very convenient, and there is no noise when switching. It is more comfortable to install in the room. Sliding doors with lower rails were originally used in wardrobes. With the progress of production technology, people choose to use sliding doors as space partition doors. The lower track mainly takes the pulley under the door leaf as the support point and slides left and right through the underground guide rail. Its main stress point is the lower pulley, which is generally assisted by the upper crawler pulley.

The main advantage of the lower rail is to separate the space, limit and separate the space to a certain extent, increase the privacy of the space and play a certain sound insulation effect. The disadvantage of lower rail sliding door is that the slide rail is easy to be damaged. Sliding doors require high quality of sliding rails and some hardware. Sliding doors are easily damaged. The service life of integral sliding door is not long, and maintenance and replacement are more troublesome. Sliding doors with lifting guide rails have certain requirements for walls. Because the sliding door with lifting guide rail is stressed on the upper rail and the upper rail is fixed on the wall, the wall of the sliding door with lifting guide rail is preferably a solid wall.

An important feature of the upper rail sliding door is that there is no threshold below, so it will not kick the threshold when walking. In addition, the sliding door of the upper track is easier to clean than the sliding door of the lower track. Just like curtains, there is basically not much dust accumulation. Some shortcomings of track sliding doors are that the installation requirements are relatively high, and there are certain requirements for load-bearing walls. If the installation is unreasonable, it may affect the service life of the door.
