As modern buildings continue to grow in size, tall doors are becoming increasingly common in commercial complexes, factories, and public spaces. During installation and use, the question of whether latches are necessary on tall doors has gradually become a focus of industry attention.
Structural Characteristics of Tall Doors
Tall doors are larger and heavier than conventional doors, placing significantly increased stress on the door leaf during opening and closing. To maintain balance and stability, they often require additional anchor points, in addition to the conventional hinges and latch body, to prevent deformation or wobbling.
Practical Functions of Latch
In tall door designs, latches are commonly used for the following purposes:
Enhancing Stability: By inserting upward and downward into the ground or doorframe, they effectively distribute the weight of the door and reduce excessive loads on the hinges.
Improving Safety: The multi-point anchoring structure increases pry resistance, making it particularly suitable for security-critical applications such as warehouses and industrial doors.
Extending Service Life: Reducing hinge loosening or deformation caused by long-term stress, thereby reducing maintenance frequency.
Not Required on All Tall Doors
It is important to note that not all tall doors require latches. If the door is made of lightweight materials or equipped with high-load-bearing hinges and a specialized locking system, design optimization can ensure stability. Furthermore, some automatic doors or fire-rated doors have specific closing and certification requirements, so latches may become an obstacle and should be used with caution.
Industry Trends and Recommendations
Currently, an increasing number of door manufacturers are adopting "multi-point locking systems" in the design of tall doors. These systems replac
