1. According to the opening and closing form: they can be divided into sliding doors, swing doors, overlapping doors, folding doors, curved doors and revolving doors.
(1) Sliding doors: They can be divided into single-opening, double-opening, overlapping single-opening, overlapping double-opening and curved doors. The curved door leaves move smoothly along the arc track and can be divided into half-arc one-way, half-arc two-way and full-arc two-way. In order to maximize the widening of the entrance, some sliding (overlapping) automatic doors can be made to open manually after the opening end overlaps with the fixed leaf, which is also classified as sliding automatic doors.
(2) Revolving doors: They can be divided into central axis type, circular guide rail hanging type and central display area type.
(3) Swing doors: They can be divided into single-leaf one-way, double-leaf one-way, single-leaf two-way and double-leaf two-way.
(4) Folding doors: They can be divided into 2-leaf folding and 4-leaf folding.
(5) Emergency evacuation automatic door: Both movable and fixed doors can be opened 90 degrees.
(6) Overlapping doors: They can be divided into overlapping automatic doors with fixed side door leaves and overlapping automatic doors without fixed side door leaves.
(7) Curved doors: They can be divided into arc segments, semicircles, and full circles. They can be with fixed door leaves or without fixed door leaves. The arc can be designed and set according to the specific case. The application is very flexible. Different arcs can also be spliced to construct beautiful and varied geometric door bodies. Therefore, the use of Caesar curved doors will become more and more widespread.
Application statistics: Sliding automatic doors are the most used, accounting for more than 90% of the total number of the four types of automatic doors, followed by rotating automatic doors, accounting for about 6%, and flat opening and folding automatic doors are the least used, each accounting for about 2%.
2. According to the door body material: Stainless steel doors have safety glass, stainless steel facings, architectural aluminum alloy profiles, color coated steel plates, wood, etc. Other materials can also be used. Common types of automatic doors made of it include frameless glass automatic doors, stainless steel frame glass automatic doors and aluminum alloy frame (planed or fluorocarbon painted) glass automatic doors.
3. According to the structural characteristics of the door, automatic doors are mainly divided into nine categories, namely automatic revolving doors, arc-shaped automatic doors, smooth automatic doors, flat opening automatic doors, folding automatic doors, telescopic automatic doors, rolling shutter automatic doors, lifting automatic doors and automatic car blockers.
