Non-standard door purchase:
1. Check the door lock performance and structure
The anti-drill lock is selected. After the drill bit is drilled into the lock hole, the lock will rotate synchronously with the drill bit when rotating, which can play the role of the lock without being damaged. The lock requires a three-way locking structure, three hinges for single door opening, six hinges for double door opening, and a door lock for the door leaf and the door frame. Even if the hinge is broken, the door cannot be opened.
2. Look at the number of locks on the door and drink the number of inserts
It is best to choose two locks to control the door of each of the two plungers, even if it can be destroyed, it will delay the time. Generally speaking, a lock can control 3 to 4 plungers. Such a door has poor anti-theft performance. Once the lock is damaged, several plungers lose their effect at the same time.
3. Look at the thickness and area of ​​the stiffener around the lock
Non-standard doors are divided into two types: closed type and fence type. Regardless of which one is chosen, the lock is the main part of theft damage. Therefore, the lock core should be a cold steel plate with a thickness of more than 2 mm. Not less than 500 mm.
4. See how the quality of the process
The choice of non-standard door materials is fundamental, and the quality of the production process is the key. In particular, attention should be paid to the presence or absence of weld defects such as open welding, unwelded welding, missing welding, and slag inclusion. Check whether the cooperation between the door leaf and the door frame is dense, whether the gap is uniform, whether the opening is flexible, whether all the joints are foraging, whether the paint plating is uniform, firm and smooth.
5. Pick from the design
The non-standard doors on the market are classified into three categories: luxury, mid-range and ordinary. The luxurious panel material is stainless steel plate, the main frame is made of stainless steel square tube, the flower decoration fence is made of stainless steel profile; the mid-range type is generally combined with square round steel and floral decoration; the common type is square steel tube, round steel and flat steel ( 16 × 4 mm) and other materials. Users can choose their favorite type according to their own situation.
In addition, when installing a non-standard door, it is required to be fixed by expansion bolts and welded by electric welding, and the fixing point is not less than 8 and 4 on one side. In terms of maintenance, it is advisable to add oil to the door shaft and the plunger every 3-6 months, so that it can be opened flexibly, but do not add oil to the lock to prevent dust and affect the performance of the door lock.
