Many consumers tend to look at the appearance and design when purchasing door and window decoration, but anyone who knows non-standard doors knows that when buying non-standard doors, they should focus on the anti-theft performance and quality, because it is related to The safety of a family and the personal safety of the family.

  How can we buy a non-standard door with good performance and quality?

  First, check the performance and structure of non-standard door locks before purchasing. A good anti-drill lock. After the drill bit is drilled into the lock hole, the lock will rotate with the drill bit when it is rotated. This prevents the lock from being damaged by the drill bit. Even if it is damaged, it will take time. Non-standard door locks require a three-way locking structure. Double-open doors have at least 6 hinges, single-open doors have at least 3 hinges, and door frames have hidden locks, so that even if the hinge is damaged, the door will not open.

  Second, carefully check the number of locks on the door and the number of pins. The locks and pins on a good non-standard door are two locks that control two pins each. Even if such a non-standard door is damaged, it will delay time. If it is a non-standard door with a lock head that can control 3 to 4 plugs, its anti-theft performance is relatively poor. Once such a door lock is damaged, several plugs will lose their function at the same time.

  Third, the area and thickness of the reinforcing plate around the lock are also crucial. From the structural design point of view, non-standard doors are divided into two types: closed and fence, but no matter which type of non-standard door is selected, the lock is the main part to be destroyed by the thief. A good non-standard door is made of cold steel plate, the thickness of the lock guard plate should be more than 2 mm, and the height of the guard plate should not be less than 500mm.

  In addition to the three points mentioned above, when installing non-standard doors, workers are required to fix the door with expansion bolts, and use electric welding to weld it to death. The number of fixing points should not be less than eight. In terms of maintenance, lubricate the door shaft and the plunger every three to four months to lubricate the non-standard door, but be careful not to add lubricating oil to the lock to prevent dust from affecting the door lock. Performance.
