Do you care if the security door creaks at home and the V-tube is in charge?

There is abnormal noise in the door leaf and door frame, which belongs to the installation problem and does not belong to the property jurisdiction.

Security doors are usually hidden hinges, and the bearings on the hinges are broken, which makes the hinges of the door leaves and the hinge boxes on the door frames grind up. You can try adding some lubricating oil. If the problem is not solved, you need to find a manufacturer to replace the bearing on the hinge.
