Automatic door is not only just glass door

When we talk about automatic door with your friends. Most of them thinking the automatic door is the glass door which we normally seen in the supermarket, shopping mall, office building,etc.

Actually, automatic door can be made into all kinds of doors as we see in the daily life,  like automatic swing door with wood material. Just the current application of automatic doors is not very extensive, it is mainly used in the entrance of the building, which habitually uses glass door panel, so people mistakenly believe that automatic door is glass door.
