Sectional doors are widely used in industrial and commercial settings, valued for their convenience, durability, and safety. However, the design of small doors within these door panels is often overlooked. This article will delve into the reasons behind incorporating small doors into door panels, providing answers to common questions.
Reasons for Incorporating a Small Door in Sectional Door Panels
Enhancing Safety
It is well-known that the opening and closing speed of sectional doors is comparable to that of standard roll-up doors, typically ranging from 0.2 to 0.3 meters per second. While some models may operate slightly faster, most products cannot achieve the rapid opening/closing speeds of high-speed doors. Consequently, users must wait for the door to fully open or reach a height allowing free passage. However, in emergencies, speed is critical. For this reason, special facilities opt to add a small personnel access door to these products, serving as an emergency exit. In unexpected situations, employees or pedestrians can quickly evacuate through this small door, enhancing the safety of the premises.
Convenient Access and Simple Operation
Installing a small door within the main door panel allows for convenient opening and closing without requiring the full lifting motion each time. This is particularly suitable for warehouses requiring thermal insulation and wind resistance. When retrieving small items or conducting inventory checks, the inner door can be opened for free access. Excessive opening can shorten the door’s lifespan, but this design also enhances work efficiency to a certain extent.
In summary, while the small door within a sectional overhead door may seem insignificant, its function and design play a crucial role in enhancing site safety, operational efficiency, and aesthetics. In critical situations at specialized facilities, it can serve as a lifesaving passageway.
