Introduction: The anti-theft door is an important guarantee of modern home security, and its level is divided into four levels: A, B, C, D, and there are great differences in the security performance, material, and other aspects of the security door. This article will give you a detailed analysis of the difference between the security door grade A, B, C, D, and help you choose the right security door for your family.
First, the security door grade classification standard
According to the relevant standards in China, the anti-theft door grade is divided into four grades: A, B, C, D, which is based on the anti-vandalism time of the door, the safety of the lock, the thickness of the door leaf and other indicators. Class A security doors have the highest security performance, while Class D security doors have the lowest security performance.
Second, the difference between the level of the anti-theft door A, B, C and D
Safety performance: The anti-vandalism time of Class A anti-theft door is not less than 30 minutes, the anti-vandalism time of Class B anti-theft door is not less than 15 minutes, the anti-vandalism time of Class C anti-theft door is not less than 10 minutes, and the anti-vandalism time of Class D anti-theft door is not less than 6 minutes. It can be seen that the security performance of Class A security doors is the highest, and the security performance of Class D security doors is the lowest.
1. Material: Grade A security doors are generally made of stainless steel, copper and other high-quality materials, with good corrosion resistance and wear resistanceClass B anti-theft doors are mostly made of ferroalloy, aluminum alloy and other materials;Class C security doors are mainly made of ferroalloy;Class D security doors are mostly made of ordinary iron plates. Therefore, the material of the Class A security door is the best, and the material of the Class D security door is the worst.
2. The higher the level of the security door, the better its safety performance, the better the material, the higher the production cost, and therefore the higher the security performance. The ** of Class A security doors is usually higher than that of Class B, Class C, and Class D security doors.
3. Usage scenario: Class A anti-theft door is suitable for places with high requirements for security performance, such as banks, gold and silver jewelry stores, etc.;Class B security doors are suitable for general homes and commercial places;Class C security doors are suitable for homes and commercial places with low requirements for safety performanceClass D security doors are suitable for places with low security requirements.

For families with limited economic conditions, you can choose a Class D security door, although the security performance is low, but it is relatively cheap.
