1. Adjust the track size appropriately. When installing pulleys, ensure the size of the track box, about 12cm high and 9cm wide. Set the track in the track box, and the height of the sliding door should exceed 1m 95 to avoid looking sunken.

2. Check whether the installation ratio is normal. Sliding door pulley specifications should be maintained at 80 to 200 cm. This size is stable and beautiful, which is the golden ratio of overall width and height.

3. Choose a suitable sliding door. The choice of sliding door is also learned. You can't use the floor type. Because of frequent use, the scope will be relatively large, and the problem of deformation will occur after a long time, which is more difficult to use later.

4. Set the track, first fix the track, then draw a fixed surface on both ends of the track with a pen, then install the track, and then fix it with a vertical line to ensure parallelism.

Second, what are the precautions for purchasing sliding doors?

1. Considering the profile of sliding door, there are common sliding door frame profiles on the surface, including carbon steel and aluminum-titanium alloy. The outer film of carbon steel is rich in color and easy to rust, while aluminum-titanium alloy is a high-strength aviation material with high strength, light weight and good toughness, but its price is very expensive.

2. Considering the pulley and slide rail, the actual purchase should be based on the installation situation. They play an important role in sliding doors, and Mg-Ti-Si alloy should be the first choice. This material has strong deformation resistance and long service life.
