What Is Collapsible Door?
A collapsible door is a unique type of door that can be opened and closed with minimal effort. This type of door is often used in situations where the width of the opening is large but the space available for a traditional hinged door is limited. Collapsible doors are typically constructed from thin, mild steel sections and can come in single or double shutter designs.
Description
Collapsible doors are designed to be space-saving and easy to use. They do not require the use of hinges or shutters for opening and closing, and even when closed, they allow for visibility through the door. These doors are typically made from vertical pieces of rolled steel channels, 16 to 20 mm wide, which are joined together with the hollows of the channels on the inside, leaving a vertical gap between them of 12 to 20 mm. Rollers are provided at the top and bottom of the door for ease of movement. The vertical channels are spaced at 10 to 12 cm center to center and are joined together by means of hoop iron cross pieces or flats, 16 mm to 20 mm wide and 5mm thick, which allow the door to open or fold. The recommended maximum height for a collapsible door is 3 meters and there are no restrictions on width.
