The security door special lock with anti-drilling function is detected by the testing center of the Ministry of Public Security. The security door can be made of different materials, but only the door that meets the standard test and receives the production permit for the security product can be called the security door. Let's take a look at how to buy a security door with Jiuzheng Building Materials Network.
First, according to the door type to distinguish
According to the different structure, the anti-theft security door can be divided into three types: the anti-theft security door, the fence-type anti-theft security door and the fence-type folding door. However, the main use of the residential door as the household door is the swing-type anti-theft security door. The fence-type anti-theft security door is mainly used in conjunction with the building intercom electronic control system products, and is used as a building intercom door for residential or residential walkways. Sliding doors are mainly used in small commercial shops.
For the average consumer, the resident's anti-theft security door is mainly a flat-open anti-theft security door. The swing door is the most demanding security door on the market. Some standards refer to this type of door as a separate door or entry door, indicating that this is a door that distinguishes between indoor and outdoor. Therefore, in addition to anti-theft, it also involves insulation, sound insulation, aesthetics and many other aspects. The swing door is divided into the form: ordinary swing door, door middle door, child mother door and composite door. The ordinary swing door is a closed door with a single fan opening.
The door in the door has the advantages of a fence door and a swing door. The part of the outer door is a fence door. There is a small door behind the fence door. The small door can be used for ventilation of the fence door. The small door is closed as a swing door. The role. The sub-mother door is generally used for homes with large door frames, which means that it is convenient to enter and exit at ordinary times, and it is also convenient for large furniture to be moved in. The composite door is also called a frame and two doors, the front door is a fence door, and the back door is a closed swing door.
Second, according to the security level
Anti-theft security doors can be divided into A-class, B-class and C-class anti-theft security doors according to their security level. Among them, C-class anti-theft performance is the highest, B-level is second, and A-level is the lowest. Most of the anti-thefts we see in the mall now are A-level anti-theft. Safety door, it is more suitable for general residents to use.
Third, from the material points
The security door is mainly divided into five kinds of materials: steel, steel-wood structure, stainless steel, aluminum alloy and copper. They have their own characteristics in terms of quality and performance, and the natural price is not the same.
Steel security door
It can be said that it is the most seen in the market and the most used by the people. Most of the security doors familiar to the people belong to this series. Such doors are cheaper and more reasonable, and their sales account for more than 90% of total market sales. The disadvantage of this type of door is that the outer lines are hard and difficult to integrate with modern interiors.
Steel wooden door
It is a kind of door that can be used for interior decoration. It can be requested by the user. The anti-theft performance is achieved by the middle steel plate. Manufacturers can choose different colors, wood, lines and patterns according to user requirements and integrate with interior decoration, no longer like the cold and uncoordinated like steel doors. Therefore, its price is also more expensive than steel security doors.
Aluminum alloy security door
The aluminum alloy material used in this kind of door is different from the ordinary aluminum alloy door and window that we have seen. Its hardness is high and the color is bright, and it is decorated with a pattern to give a golden feeling. It is a mid-range security door. Because this kind of door is not easy to fade, it also has a certain consumer group.
Stainless steel security door
The stainless steel security door is rugged and safer. At present, the stainless steel security door in the market is too monotonous in color, basically silvery white. This color makes people feel very blunt, and it is not easy to coordinate with the door and the surrounding environment, and if there are collisions and welding marks on the surface, it will be very obvious. Due to the price factor of stainless steel itself, its price positioning is also higher.
Copper security door
Most of the copper security doors combine the traditional anti-theft and the entrance door into one, with advanced styles, and have good performance in fireproof, anti-corrosion, anti-mite and dustproof. From the material point of view, the copper security door is the best, from the price point of view, it is also the most expensive, the basic price that can be seen in the market is about 5,000 yuan, the most expensive can be 10,000 yuan.
