With urbanization and space constraints, Bifold doors have grown in popularity as a space-saving and flexible door option. It saves internal space and is an excellent choice for limited space. In this post, we will look at the working principle and structure of folding doors.

Basic Overview of Bifold Doors:

Bifold doors are special types of doors comprising two or more panels connected by hinges to open and close in a folding manner. They follow key features:

1. Multiple door panels: Exterior bifold doors comprise multiple door panels, an even number, connected to each other by hinges. This allows the door to be folded and stacked on its side when opened, saving space.

2. Folding operation: External bifold doors are designed to allow opening and closing by folding along the hinges. When opened, the door panels fold along the center hinge, creating an accordion-enjoy stacking structure.

Folding door application areas：

1.Commercial premises: Exterior bifold glass doors have a wide range of applications in commercial premises such as restaurants, stores and exhibition spaces. They can be used as indoor and outdoor dividing doors, entrance doors or display windows, bringing aesthetic, practical and flexible solutions to commercial environments.

2.Outdoor space: Folding doors are a popular choice in outdoor spaces like balconies, courtyards, and terraces. They can create open spaces that connect indoors and outdoors, provide natural light and ventilation, and increase interaction with the outdoor environment.

How Folding Doors Work:

A. Opening process

1. What rollers and tracks do: Folding doors usually have a system of rollers and tracks that hold the door panels in place and help them move. The tracks are attached to the floor or ceiling, and the rollers are on top of the door panel. By sliding on the tracks, the rollers make it easy for the door panels to move smoothly along the rails.

2.The folding mechanism's operation: The folding mechanism for a folding door is placed at the hinge between the door panels. When the folding door is opened, the folding mechanism begins to work. It allows the door panels to fold along the hinge axis and stack to one side. The design of the folding mechanism and material selection are important to ensuring smooth folding and sturdy stacking of the door panels.

B.Closing Process

1. How the door panel unfolds and lays flat: When the bifold exterior door needs to be closed, the operator can push or pull the door panel to unfold and lay flat in its original position. The roller and track system support and guide the door panel, ensuring that it moves smoothly during the closing operation.

2. The function of the operating system: Outside bifold doors are typically supplied with an operating system to facilitate opening and closing. The operating mechanism can be manual, requiring human force to open and close the door panel, or electric, utilizing a motor or drive to automate the functioning of the door panel. Motorized operating systems are frequently outfitted with switches or remote controls that enable the user to effortlessly regulate the movement of the folding door.

A folding door's working concept is based on the support of a roller and track system, the coordinated work of the folding mechanism, and the operating system's drive. These parts work together to ensure that the folding door opens and closes smoothly, making it comfortable and easy to use in practical situations.
