The security door is the security guardian of the consumer family. A good security door can protect the safety of a family very well! Because of these factors, the correct and appropriate purchase of security doors has become a matter of great concern to consumers. The door network believes that the security door purchase should pay attention to check the performance and quality, how to view it?
First, first check the security door lock performance and layout. The anti-drill lock is selected. After the drill bit is drilled into the lock hole, the lock will follow the drill synchronous twist when twisted, which can play the role of the lock without being crushed. The lock requires three-way locking layout, three hinges for single door opening, six hinges for double door opening, and a frame lock for the door sill and the door. Even if the hinge is broken, the door cannot be opened.
Second, it is to look at the number of locks on the door and the number of inserts. It is best to choose two locks to control the two levers of the door. Even if it can be crushed, it will delay the time. Generally speaking, a lock can control 3 to 4 plungers. This kind of door has poor anti-theft performance. Once the lock is damaged, several plungers will be used at the same time.
Next, look at the thickness and area of ​​the stiffener around the lock. The security door is divided into two types: the closed type and the grid type. The lock is the primary part of the theft and the smashing. The lock protector should be a cold steel plate with a thickness of more than 2 mm. Not less than 500 mm.
Then, it depends on the quality of the process. The choice of security door material is the foundation, and the quality of the production process is the key. Special attention should be paid to checking for weld defects such as open welding, unwelded welding, missing welding, and slag inclusion. Whether the matching of the door sill and the frame of the door is dense, whether the gap is uniform or not, whether the opening is flexible, whether all the joints are for food, whether the paint plating is uniform, firm and smooth.
Of course, the design is also very important. The security doors on the market are classified into three categories: luxury, mid-range and ordinary. The luxurious panel material is made of stainless steel, the main frame is made of stainless steel square tube, the flower decoration grid is made of stainless steel; the mid-range type generally adopts the combination of square round iron and floral decoration; the ordinary type adopts square steel tube, round iron and flat steel. (16 × 4 mm) and other materials. Users can choose their favorite type according to their own situation.
Choose a suitable security door, learn to see the quality and performance correctly!
