Aluminum alloy folding doors with lower tracks and without lower tracks have their own advantages and disadvantages. Choosing which one is better depends on personal needs and actual conditions.

Aluminum alloy folding doors with lower tracks have the following advantages:

Good stability: The lower track can provide better support and guidance, making the door leaf more stable when folding and sliding, and not prone to shaking or tilting.

Good sealing: It can effectively prevent wind, sand, dust, garbage and rainwater from leaking into the room.

Relatively simple installation: The technology is relatively mature and the installation process is relatively easy.

Folding doors with tracks also have some shortcomings:

Easy to accumulate dust: Dust, debris, etc. are easily accumulated in the track groove, which may be more troublesome to clean.

May form obstacles: The track on the ground will have a certain bulge, which may cause slight obstruction to people walking or objects moving, and is not suitable for places where wheelchairs or strollers often pass through.

The advantages of aluminum alloy folding doors without lower tracks include:

Good aesthetics: There is no track on the ground, and the overall look is more concise, beautiful, and more visually coherent.

Easy to clean: There is no problem of dust accumulation in the track groove, and daily cleaning is more convenient.

Barrier-free passage: There will be no bulges on the ground, which is convenient for people and objects to pass freely.

However, there are some things to note about folding doors without lower tracks:

High requirements for installation and accessories: Usually better hardware accessories are required to ensure the stability and smooth operation of the door leaf, so the cost may be relatively high.

Stability may be slightly inferior: Its stability may be weaker than that of folding doors with lower tracks.

When choosing, you can consider the following factors: If you pay more attention to stability, sealing and convenience of cleaning, and don’t mind the existence of ground tracks, folding doors with lower tracks may be a better choice; if you pursue a simple and beautiful appearance, barrier-free passage, and are willing to invest more in installation and accessories to ensure quality, then folding doors without lower tracks may be more suitable.
