We need it for our private life. So, how can I choose a lock that is both satisfactory and durable? Below, we will start from the security door.

Type of security door:

The full name of the security door is called "anti-theft security door". It combines theft and security features. According to the "General Technical Conditions for Anti-theft Security Doors", qualified security doors can not be opened or opened with a portable electric tool such as a chisel, a screwdriver, a crowbar, etc. within 15 minutes or a 615 mm2 on the door leaf. Open, or open a 38 mm square opening in a semicircle of 150 mm square. And the lock used on the security door must be a security door lock with anti-drilling function that has passed the test 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.

The biggest feature of the security door is its strong security, sturdy and durable, flexible opening and beautiful appearance. Security doors are suitable for civil buildings and residential buildings, high-rise buildings and confidential rooms, and finance departments.

At present, there are many types of security doors on the market. According to the GB25-92 "General Technical Conditions for Security Doors" issued by the Ministry of Public Security, the security doors can be divided into three types: fence-type security doors, physical doors and composite doors.

The fence type anti-theft door is a common anti-theft door welded by steel pipes. Its biggest advantage is ventilation, light weight, beautiful appearance and relatively low price. The upper part of the security door is a fence type steel pipe or steel plate, and the lower part is a cold-rolled steel plate, which is locked by multiple lock points to ensure the anti-smashing ability of the security door. However, it is not as good as the closed security door in the anti-theft effect.

The solid door is extruded from cold-rolled steel plate, and the door panels are all steel plates. The thickness of the steel plate is 12 mm and 15 mm, and the impact resistance is strong. The door double-layer steel plate is filled with rock wool insulation fireproof material, which has the functions of anti-theft, fire prevention, heat insulation and sound insulation. General physical security doors are equipped with cat eyes, doorbells and other facilities.

The composite anti-theft door is composed of a solid door and a fence-type anti-theft door. It has the characteristics of anti-theft and summer fly-proof mosquitoes, ventilation and cooling, and warm insulation in winter.
