How to Choose a Security Door

After reading the following 5 experiences, I immediately have a clear idea!

Home decoration generally belongs to interior decoration. Many owners only care about indoor conditions, but ignore a very important point. It is the home Security Door treatment. Anti-theft doors, as the name suggests, are used to prevent theft. When decorating your home, how should you choose anti-theft doors?

1: How to choose security doors

1. Choose according to door size and opening direction
Standard doors for homes generally come in four specifications, represented by a four-digit number consisting of the width and height of the building opening. Users can choose the appropriate anti-theft Safety Door according to the size of the door opening, the direction of the door opening, color pattern and other actual requirements.

2. Pay attention to the surface quality and safety of security doors
The thickness of the steel plate used for the door frame of the steel anti-theft door should not be less than 2 mm. The thickness of the steel plate used for the front and rear panels of the door leaf is generally between 0.8 and 1 mm. The thickness of the door body is generally more than 20 mm. The weight of the door body should be checked. Generally, the thickness of the steel plate should be Above 40kg. Check the anti-theft door grade steel seal on the inner door hinge. If there is no steel seal, it does not meet the requirements of the national standard and is not a security door.

Pay attention to the safety of anti-theft door hardwareThe anti-theft performance of anti-theft doors mainly depends on the performance of keys and locks. Therefore, when selecting anti-theft doors, you must check whether the locks use special anti-theft locks that have been tested by the public security department, whether there are reinforced steel plates for protection at the installation location of the locks, and check the keys and Lock performance reports. There are three levels of anti-theft door lock cylinders, namely ABC (Super Class B), among which Super Class B locks are the safest.

4. View the structure and craftsmanship of security doors
Remove the cat eye, doorbell box or lock handle and check the internal structure of the door body. There should be several reinforcing steel bars inside the door to organically connect the front and rear panels of the door. It is best to use asbestos and other materials with fireproof, thermal insulation and sound insulation functions as fillers inside the door. Check the workmanship quality of the product, whether there are welding defects, whether the door leaf and door frame fit tightly, etc.

5. Choose professional brand Security Door Products
The brand of anti-theft doors is a symbol of product quality and service. When purchasing anti-theft doors in the market, it is best to go to a regular large home building materials store. When purchasing, you should also pay attention to the "FAM" logo, company name, implementation standards, etc. of the anti-theft door. Only doors that meet the standards are safe and reliable. When customizing or purchasing security doors, you should purchase qualified products from manufacturers that have obtained the "Production License Registration Certificate" issued by the public security bureau. If necessary, you can ask the seller to produce the "Test Certificate" from the relevant department.

2: What are the materials of anti-theft doors?

Most of the common anti-theft door materials on the market are made of steel, but there are also anti-theft doors made of other materials, which can be divided into five types: steel, stainless steel, copper, steel-wood structure and aluminum alloy.
1. Steel security door
This type of door is relatively cheap and reasonable, and its sales account for more than 90% of the total market sales. The disadvantage of this type of door is that the exterior lines are hard and difficult to integrate with modern interior decoration.

2. Copper security door
It has high safety, strong practicality, beautiful appearance, and has good performance in fire protection, anti-corrosion, anti-prying and dust-proof. But they are expensive. The basic prices seen on the market are around 5,000 yuan, and the most expensive can be tens of thousands of yuan. It is mainly used in financial institutions such as banks or high-end residential villas.

Stainless steel security door Stainless steel anti-theft doors are strong, durable and safer. At present, the color of stainless steel security doors on the market is too monotonous, basically silver-white. This color makes people feel very stiff, and is not easy to coordinate with the door and the surrounding environment. Moreover, if there are traces of collision and welding on the surface, it will be very difficult to obvious.

4. Steel-wood security door
A kind of door that can be matched with interior decoration. The manufacturer can choose different colors, woods, lines and patterns according to user requirements to integrate with the interior decoration. It is no longer as cold and uncoordinated as steel doors. Therefore, it is more expensive than steel anti-theft doors, is heavier, and has high requirements for door frames and hinges.

5. Aluminum doors
It is a mid-range anti-theft door with high hardness and bright color. It is decorated with patterns and patterns, giving people a sense of splendor. However, it has poor air tightness, high precision requirements, and certain installation skills.

Three: Anti-theft door lock cylinder level

Anti-theft door lock cylinders are basically divided into two levels, namely Class A and Class B; of course, some companies now produce super-B-level lock cylinders according to market demand, and C-level lock cylinders are the same as super-B level. Among them, the anti-destructive opening time of the A-level lock cylinder is greater than 15 minutes, and the anti-technical opening time is greater than 1 minute; the anti-destructive opening time of the B-level lock cylinder is greater than 30 minutes, and the anti-technical opening time is greater than 5 minutes; and the super-B level lock cylinder Generally speaking, the anti-theft door lock cylinder has a technical opening time of more than 4 hours.

1. Grade A lock cylinder
The anti-theft coefficient is the lowest, and for thieves, it can be opened in minutes!
Class A locks refer to locks using Class A lock cylinders, generally including traditional one-word locks, cross locks, crescent locks, and most locks with only one row of marble structures in the lock cylinder. Their anti-theft properties are poor, and the opening time is generally A few seconds to two minutes. The lock cylinders used by many developers when handing over properties are Class A locks.

2. Class B lock cylinder
Class B locks are much better. They are single row and curved. The difference from Class A locks is that there is an extra row of curved and irregular lines on the key surface. It can basically meet the anti-theft performance that anti-theft doors should have.

3. Super Class B lock cylinder
Super B-level lock cylinders are actually similar to C-level lock cylinders. They use multiple anti-theft technologies and a variety of special-shaped anti-pull pins to prevent technical openings. With the unique pin and blade structural design, they have high security performance against technical openings. The lock cylinder is equipped with a structure of precision numbered marbles and special-shaped marbles. When the technical opening is performed, the numbered marbles and special-shaped marbles must be pulled at the same time, and the lock will be automatically locked, thus making the technical opening unsuccessful. Super B-level lock cylinders are currently very high-performance lock cylinders. Only with good lock cylinders can you be assured of safety.
