What is the difference between a fire door and a security door?

Doors are very common in daily life and play a very important role. With the improvement of living standards, consumers demand more and more diversified functions of doors, not just the function of sheltering from the wind and rain as before. With the development of science and technology, the material of doors has changed accordingly. According to the different materials and workmanship, the existing doors have the functions of fire prevention and theft prevention. So, what's the difference between a fire door and a security door? Let's take a look at the specific introduction.

Brief introduction of fire door

Fire door refers to the door that can meet the requirements of fire stability, integrity and heat insulation in a certain period of time. The main purpose is fire prevention and strong fire resistance. Therefore, it is necessary to choose materials with high flame resistance and high temperature resistance, which not only do not release toxic gases themselves, but also prevent toxic gases from entering. Generally speaking, fire doors have the characteristics of smooth appearance, elegant appearance, sensitive opening, durability, convenient use, safety and reliability. According to the material, there are wood fire doors, steel fire doors, steel wood fire doors, other fire doors and so on.

Brief introduction of security door

The full name of the security door is "anti-theft security door", which has both anti-theft and safety functions. The lock that needs to be used on the security door is a special lock with anti-drilling function that has been inspected by the inspection base of the Ministry of Public Security. Security doors can be made of different materials, but as long as they meet the standards and pass the inspection, the door that receives the certificate of safety protection products can be called security doors. According to the anti-theft safety level, it is divided into four levels: A, B, C and D, which decrease from high to low.

The difference between security door and fire door

The difference between a security door and a fire door is that the main function of the security door is to prevent prying and better sealing performance. Generally, you can't open the door without a key outside the back door, and the filler in the door panel is not fireproof material. The security door must be marked with the word "FAM" and refer to the General Technical Conditions for Security Doors GB 17565-2007. Although the fire door is also made of steel, the door panel is filled with fire-proof materials, and the thickness of the door steel plate also has different requirements. Steel doors are ordinary steel doors, which also have certain anti-theft function but poor anti-prying performance. Generally, street processing factories are like this. Only Shanghai and Chengdu have local standards for fire-proof security doors, and those in other places can only be called fire-proof entrance doors, that is, they have reached the national fire-proof A-class or B-class fire-proof door standards, and the A-class and B-class standards (filled with fire-proof door cores) are generally divided by fire-proof time. At the same time, meet the following requirements for anti-prying:

1, door frame thickness 1.5, and the thickness of steel plates on both sides of the door leaf is 0.8.

2. The lock has the function of anti-prying, that is, the lock body has both oblique locking tongue and square locking tongue, which has the function of quick opening, preferably twist type, but it is not allowed to install heaven and earth locks.

3. The locks and cat's eyes should have fire detection reports. Class B fire doors can be fitted with knockers, but Class A can't.

4. At the time of acceptance, the merchant shall provide the fire type approval certificate, fire detection report and metal entrance door detection report. Fire detection report of lock and cat's eye.

5. The door leaf opens in the direction of rapid evacuation and cannot be opened inside.

The above is a concrete introduction about the difference between fire doors and security doors. I believe that after reading Bian Xiao's introduction, you can understand their differences and what problems should be paid attention to when purchasing. Whether it is a fire door or a security door, in the final analysis, it still plays a role in protecting our lives. So remember to choose a door that doesn't pass the material when you buy it, because it's cheap. So much for the introduction. I hope Bian Xiao's sharing can help everyone.
