Anti-theft doors are an indispensable item in the lives of modern people, but can we have a more comprehensive understanding of it?

Anti-theft door-as the name implies, its most important function is anti-theft, to be precise, it is to prolong the time for criminals to commit crimes, so as to play a role in guarding the nursing home, protecting user property and personal safety. Therefore, the longer the protection time, the more anti-theft.

1. Security of anti-theft door The anti-theft door is mainly composed of steel door leaf, door frame and anti-theft lock. The door leaf is generally composed of front and back steel plates plus filler. Therefore, its safety mainly depends on: â‘  the anti-destruction time of the door, â‘¡ the anti-technical opening time of the lock.

2. The anti-destructiveness of the door is measured by "anti-destruction time" (the national standard requires no less than 15 minutes), which refers to using chisels, hammers and other manual or portable electric tools to open the door or dig through a 615 square centimeter mouth , The required net working time.

3. The anti-technical opening of the lock is measured by the "anti-technical opening time" (the Ministry of Public Security stipulates that the anti-technical opening is 1 minute for class A and 5 minutes for class B). The time required to open the lock.
The lock is the heart of the door, you should try to choose a lock with a high protection level, and pay attention to check the test report of the lock.

4. Convenience of use The door is a necessary place for entry and exit every day, and it is convenient and time-saving. It is unremarkable to save a few seconds at a time, and the cumulative savings over several years of use add up. And the more inconvenient it is, the easier it is to make mistakes, such as missing locks and forgetting locks.

5. The aesthetics of styles Under the premise of satisfying safety and convenience, you should try to choose beautiful and durable styles.

6. Flatness of the facade Famous brand manufacturers generally introduce large-scale equipment to suppress the facade. The flatness is relatively high, otherwise the facade may be wavy.

7. The quality of surface paint should pay attention to whether the paint is beautiful, whether the color of the door frame is consistent, whether the paint is uniform, whether there are bumps or small concaves.

8. The reputation of the brand The door is durable goods, it will inevitably encounter problems after a long time. Choose famous brand products with good reputation, quality and service are guaranteed.

9. The price and performance ratio is genuine. The price seems to be cheap, but if the key features such as product functions and locks and steel plates are discounted, which increases the hidden safety risks, it will be outweighed. Therefore, if you are not afraid of comparing the goods, you are afraid of not knowing the goods.

Some misunderstandings when buying a door:
Myth 1: The thicker the door, the more anti-theft. The anti-destruction time is mainly related to the thickness of the steel plate, and not to the thickness of the door.

Misunderstanding 2: Only pick the door but not the lock. Most people only look at whether the door is anti-pry, but forget that the door is anti-theft, and the lock is the most important. Destructive openings have been greatly reduced due to easy exposure. Technical opening is often hidden because of concealment, and it is often difficult to prevent.

Myth 3: Cheap is discount. The discount is cost-effective. Buying a few hundred yuan to open a one-minute anti-theft door for a few months is better than buying a two-pack of cigarettes a month and spending more money to buy a 180-minute anti-theft door for 180 minutes.
