Do not know it does not matter, today Xiao Bian gave you talk about how to choose the security door. Let you choose a beautiful and safe security door.
First of all, let's get to know the security door production material classification
Security doors are mainly divided into five kinds of material : steel, steel and wood structure, stainless steel, aluminum alloy and copper, which have their own characteristics in terms of quality and performance, and natural prices are not the same.
Steel
It can be said that it is the most commonly seen in the market and the most commonly used by the common people. Most of the security doors that people are familiar with belong to this series. This kind of door is cheaper and more 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 it is difficult to integrate with modern interiors.
2. Steel door
It is a kind of door that can be matched with interior decoration. Generally, it can be requested by the user. The anti-theft performance is achieved through the middle steel plate. The manufacturer can use different colors, wood, lines and patterns to integrate with the interior decoration according to the user's requirements. It is no longer as cold as the steel door. Therefore, its price is also more expensive than steel security doors.
3. Aluminum alloy
The aluminum alloy used in this type of door is different from ordinary aluminum alloy doors and windows that we see. It has a high hardness and a bright color. It is decorated with a pattern and gives a sense of splendour. It is a mid-range security door. Because this door is not easy to fade, it also has a certain consumer group.
4. Stainless steel
Stainless steel security doors are rugged and more secure. Market stainless steel security door has many colors, there are silver white, yellow titanium gold, rose gold, red titanium gold, black titanium gold, rose red, and many other colors, there are also stamping patterns, general steel security doors in the stainless steel door On the general can be achieved, the market price of stainless steel door ranging from 400-700, depending on the material is 201 or 304. Stainless steel door is best to choose larger manufacturers from the installation site near, to do after-sale price comparison.
5. Copper
Most of the copper anti-theft doors combine the traditional anti-theft door and household door into one, the style is advanced, and it has good performance in fire protection, anti-corrosion, anti-smashing and dust prevention. From the material point of view, copper security door is the best, from the price point of view, it is also the most expensive, the market can see the basic prices are more than 10,000 yuan, the most expensive up to several hundred thousand dollars. It is mainly used for financial institutions such as banks or high-end residential villas.
So how do you choose a security door?
1. Understand the standard
Security doors are divided into grades. From its security level, security doors can be divided into four levels: A, B, C, and D. As the name implies, the performance of the Class A security door is the best. Most of the common appearances in the market are Class C and Class D, which is the security door that is suitable for general household use. According to China's only standard for the inspection of security doors is the use of some sharp tools in a certain period of time can not break this door, then it is considered a real material security door.
2. The difference between genuine and fake security doors
Anti-theft security doors are produced according to national standards. Steel doors, metal doors, and entry doors are manufactured according to corporate standards. Therefore, seeing the standards becomes the first step for consumers to identify security doors. Open the door to see if there is no sign on the upper corner of the door to attach the anti-theft security door. Note that it is a "security door." If there is no such sign or sign on the metal door, steel door, or door, it is not a security door.
3. Check the steel plate
In the requirements of the steel plate thickness of the security door, according to the relevant regulations of the country, the thickness of the steel plate must reach at least 1 mm, and for some manufacturers, in order to reduce the cost and did not meet this requirement, when consumers inspect the steel plate, You can press the steel plate in the door leaf to judge whether it is qualified or not. If the steel plate is pressed down, it reminds you that the quality of the anti-theft door is not closed and abandoned.
4 understand the thickness of the plate
The general technical conditions of the anti-theft security door implemented on April 1, 2008 stipulated in GB 17565-2007:
1 Anti-theft security doors should have a permanent security level marking.
2 The anti-theft security level mark consists of its Chinese code and plane circle. The Chinese code should be located in a plane circle with a diameter of Φ25mm.
3 The Chinese Grade Marks A, B, C, and D are permanently attached to the upper corner of the inner hinge in the form of Arial gravure, and are located 1600mm±100mm above the floor height.
National standards require that stamps be made on the doors. If you do not see stamps on the doors, they do not meet the requirements of the national standards. Obviously, it is not a security door.
5. Test down the tread
For the security door, it is mainly made of stainless steel. This kind of security door can be said to have excellent stability and firmness. In order to reduce costs, many small workshops now use stainless steel instead of stainless steel. Therefore, in this small series teach you a small trick to identify, put the magnet on the bottom of the security door, if the suction is relatively strong and difficult to remove, then the surface of the tread material is used stainless iron, that is not Qualified material.
6. Check the lock point
The last test is the lock on the security door, and now some businesses use the security door with more lock points to attract customers, and precisely because of this many consumers mistakenly believe that the more locks on the security door, the better the security effect, in fact, this it is wrong. The so-called good lock is not a lock point, but to see the most critical of the lock position. The commonly used security doors for locks are all three-position locks, ie, door locks and upper and lower crossbar locks. The material of the lock core is also the key, the material of the lock core is not anti-theft, then more lock points of the security door are useless.
7. Look anti-theft performance
Anti-theft door anti-theft property is high In addition to the steel plate needs to meet national standards, locks are the most important thing.
The security door rating locks are also graded:
A-level parallel locking bolt, the key is flat, there is drip groove above. Anti-technology is turned on for less than 5 minutes.
Class B parallel bolt, key semi-circular, with a profiled tooth slot. Anti-technical open over 5 minutes in line with the national standard.
Super B-level small handsome Manshen lock body for the T-type rotary bolt, after the lock automatically rotates 90 degrees, the lock cylinder is a double-row marble step-by-step rotation control, the key is double bilateral teeth, the equivalent of two keys to knead a synthesis. Anti-technology is turned on for 270 minutes.
8. Security door style
Although the main function of the security door is anti-theft, but at the same time, the manufacturers also pay attention to the design and style of the door, which undoubtedly added a new selling point for the security door. Can buy security doors with beautiful appearance and good anti-theft performance? For consumers, it is not a double benefit? The security performance of security doors mainly depends on the level of the door and the level of the lock.
9. Look at the welding point
Under normal circumstances, the overall stamping of the security door is better than the security of the welded door, of course, the overall stamping technology generally requires the import of expensive equipment, so that the product cost has certainly been improved.
Xiaobian conclusion: In addition to the above points in the actual purchase, but also need to pay attention before the purchase of goods than three, from the quality, price, after-sales service and many other aspects of comprehensive considerations, but also according to their own home size, in the open Whether the door leaf is easy when the security door and the security door are closed, whether the door lock is flexible, and the soundproof effect of the security door cannot be less! Of course, the work of the security door and the rationality of its structure must also be considered. About the introduction here, I hope to help everyone.
