2. What happens when you use the hardware incorrectly?
Although the doors of wooden doors and metal doors function similarly, the internal structure is completely different, and the wrong use of accessories can cause 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 being drilled, and the screws are easily pulled out; the lock body mounted on the door is also prone to loose dislocation and the phenomenon that the door cannot be closed. However, due to the insufficient thickness of the ordinary hinge, it also causes excessive stress, which will cause the whole door to tilt or even fall.
