It has the function of controlling the pedestrian flow, preventing unauthorized departure and theft, and guaranteeing the safety of indoor personnel.

2.       What happens when you use the hardware incorrectly?

 

Although wooden doors and metal doors function similarly, the internal structure is completely different, and the incorrect use of accessories will cause unwanted problems.

The most obvious problem is the use of wooden door screws and hinges mounted on the steel door. The wooden door screws need to be drilled into the wood and embedded in the wood to be firm. However, since the internal structure of the metal door and the door frame are hollow, the wooden door screws are not subjected to the surrounding force after drilled and easily pulled out; the lock body mounted on the door is also prone to loose or dislocation and the situation that the door cannot be closed. However, the insufficient thickness of the ordinary hinge will lead to excessive stress, which consequently brings about a tilted or fallen door.
