When installing fast stacking doors for factory buildings and underground garages, we have to consider a variety of issues, including brand, configuration, price, and determining the installation position, opening method and passing size of the door according to the situation at the scene.
The so-called passing size is the width of the inside of the two door frames and the vertical height from the ground to the lower end of the folded curtain when the quick door is fully opened, which is the effective space for vehicles to pass.
So how is this dimension calculated?
What is the opening height of the “Ziyang Express Gate” 3.5 high-hole entrance gate?
We all know that when installing fast-stacking doors, the track, door cover, and the folded curtains take up some space. To calculate the passing size, we need to know the data: the size of the door, the height of the door cover, and the curtain. The height of the track, the width of the track.
Calculated as follows:
：制作宽-180*2 Passing width : production width -180 * 2
Passing height: production height -1000
Of course, this refers to a standard-size door. If the size of the fast-stacking door is relatively large, the corresponding data of the door will also be adjusted.
In terms of our question at the beginning, if there is no space above the doorway for the 3.5-meter-high entrance, then it is 3500-1000, and the passing height is 2500mm.
方式。 Therefore, the calculation of the opening height of the stacking door mainly depends on the site environment and installation method.
