1、按启闭形式分：可分为推拉门、平开门、重叠门、折叠门、弧形门和旋转门。
1. According to the form of opening and closing, it can be divided into push and pull doors, flat open doors, overlapping doors, folding doors, arc doors and revolving doors.
⑴推拉门：可细分为单开、双开、重叠单开、重叠双开和弧形门。弧形门门扇沿孤形轨道平滑移动，可分为半弧单向、半弧双向、全弧双向。为了最大限度的拓宽入口幅度，有的推拉（套叠）自动门可作成在开启终点与固定扇重合后一道手动平开，也归纳为推拉自动门。
(1) Push-pull door: It can be divided into single open, double open, overlapping single open, overlapping double open and arc door. The arc door and fan move smoothly along the solitary track, which can be divided into half-arc unidirectional, half-arc bi-directional and full-arc bi-directional. In order to maximize the entrance range, some push-pull (cascade) automatic doors can be manually opened flat after the opening end coincides with the fixed fan, which is also summarized as push-pull automatic doors.
⑵旋转门：可细分为有中心轴式、圆导轨悬挂式和中心展示区式等。
(2) Rotary door: It can be subdivided into central axis type, circular guide suspension type and central display area type.
⑶平开门：可细分为单扇单向、双扇单向、单扇双向和双扇双向。
(3) Flat open door: It can be subdivided into single one-way, double one-way, single two-way and double two-way.
⑷折叠门：可细分为2扇折叠和4扇折叠。
(4) Folding door: It can be subdivided into 2 folding doors and 4 folding doors.
⑹重叠门：可分为带固定边门页的重叠自动门和没有固定边门页的重叠自动门
(5) Overlapping doors: they can be divided into overlapping automatic doors with fixed side pages and overlapping automatic doors without fixed side pages.
⑺弧形门：可分弧段、半圆、全圆，可以带固定门页，也可以没有固定门页，圆弧度可根据具体案例设计设定，应用非常灵活，还可以应用不同弧度拼接，构造出美观多变的几何形状的门体，因此，凯撒弧形门的使用将越来越广泛。
_arc door: can be divided into arc section, semi-circle, full circle, with fixed door pages or without fixed door pages, arc can be set according to specific case design, application is very flexible, but also can be used to splice different arcs to construct beautiful and changeable geometric shape of the door body, therefore, the use of Caesar arc door will be more and more. Extensive.
