In some luxury villas we can see some strange entry doors, which we call non-standard doors. The simple understanding of the non-standard security door is not the door that is made by installing the design dimensions of the conventional interior door. At present, the non-standard door prices and specifications produced by the top ten brand manufacturers in China are different. How can we distinguish the non-standard? At the same time, mastering the size ratio of the non-standard door is the most concerned topic for many consumers to purchase non-standard doors.

What is a non-standard door, non-standard door is a very complicated door, it is mainly no fixed size, no fixed style, generally customized according to customer requirements. The standard door refers to the single door of the 860x2200. The general size is around this, also called the entrance door. Whether the door is a non-standard door or a standard door has nothing to do with the material, only the size. In a word, a non-standard door is an unconventional door that can be made into a peculiar door or a non-standard door.

When purchasing non-standard doors, the focus should be on observing the anti-theft performance and quality. It should be checked from the following key parts:

The first one you can check the lock performance and construction

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 prevent the lock from being destroyed. The lock request three-position locking structure, three hinges for single door opening, six hinges for double door opening, and a door lock for door leaf and door frame. Even if the hinge is broken, the door cannot be opened.

In one you can see the number of locks on the door

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.

Then you can carefully study the thickness and area of ​​the stiffener around the lock.

The non-standard door is divided into two types: the lock type and the fence type. Regardless of which one is chosen, the lock is the main part of the theft. Therefore, the lock guard should be a cold steel plate with a thickness exceeding 2 mm and the height of the core. Not less than 500 mm.

Of course, the quality of the non-standard door is also critical.

The selection of non-standard door data is basic, and the quality of manufacturing 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. Whether the cooperation between the door leaf and the door frame can be dense, whether the gap can be evenly divided, whether the opening can be sensitive, whether all joints can be eaten, whether the paint plating can be evenly sturdy and lubricated.

Finally, you can choose from the design

The non-standard doors on the market are divided into three categories: luxury, mid-range and ordinary. The luxury 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 usually made of a combination of square steel and floral phase separation; the common type is square steel tube, round steel and flat steel ( 16 × 4 mm) and other information. Users can choose the type they like according to their own situation.

In addition, when the device is not a standard door, it is requested to be fixed by shrink 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 to make it sensitive to open, but do not add oil to the lock to prevent dust and affect the performance of the door lock.

The non-standard door is now mainly used in the entrance door and the entrance security door. The use of the non-standard door is not very much. Finally, remind friends that when buying non-standard doors, they must pay attention to their own door frames and The size and custom non-standard door size, if the custom non-standard door size and door frame size does not meet the non-standard door is very difficult.
