When purchasing a non-standard door with better performance and quality, it is mainly distinguished from several aspects:
First, check the performance and structure of non-standard door locks before purchasing. A good anti-drilling lock, after the drill is drilled into the lock hole, the lock will rotate with the drill when it rotates, which prevents the lock from being damaged by the drill. Even if it is to be damaged, it will take a certain amount of time. Non-standard door locks require a three-way locking structure, at least 6 hinges for double doors, at least 3 hinges for single doors, and door frames and doors with dark locks, so that even if the hinges are damaged, the door cannot be opened.
Second, carefully check the number of locks and rods on the door. The best locks and rods on non-standard doors are 2 lock heads each controlling 2 rods. Even if such a non-standard door is destroyed, it will delay for a certain time. However, if it is a non-standard door with a lock head that can control 3 to 4 insertion rods, its anti-theft performance is relatively poor. Once such a door lock head is damaged, several insertion rods will lose their function at the same time.
Third, the area and thickness of the reinforcing plate around the lock are also crucial. In terms of structural design, non-standard doors are divided into two types: closed type and fence type, but no matter which type of non-standard door is selected, the lock is the main part that thieves want to destroy. 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 heart plate should not be less than 500mm.
In addition to the three points mentioned above, when installing a non-standard door, it is best to ask the worker to fix the door with expansion bolts, and to weld it to death with electric welding. It is best to have no less than eight fixing points. In terms of maintenance, it is best to lubricate the door shaft and plunger every three or four months, so that the non-standard door can be opened flexibly, but be careful not to add lubricating oil to the lock head to prevent dust from affecting it. The performance of the door lock.
Many consumers tend to focus on the appearance and design when purchasing doors and windows and other facade decorations, but those who know about non-standard doors know that when purchasing non-standard doors, they should focus on their anti-theft performance and quality, because it is related to To the safety of a family and the personal safety of family members.
