Floor tracks are installed on the floor and have the advantages of stable load-bearing and good sealing performance, making them suitable for use in places with smaller indoor spaces. However, floor tracks require pre-reserved grooves, which are more complicated to install and prone to dust accumulation, posing a tripping hazard. Hanging tracks are installed on the ceiling, with no tracks on the ground, maintaining the integrity of the floor, making it easy to clean and beautiful. The load-bearing capacity of hanging tracks is mainly concentrated on the tracks. If the door leaf is heavy, it may put pressure on the tracks. The installation of hanging tracks requires drilling holes in the ceiling, which poses a safety hazard.
