Anti-theft door full name anti-theft security door, the latest national standards "anti-theft security door general technical conditions", the security door anti-theft level is divided into: A, B, C, D four levels. This year, the country has newly introduced a new standard for security doors. It must be said that many users do not understand it well. Today, Xiao Bian gave everyone a talk about the country's newly introduced national standards for security doors .
New National Security Door National Standard
The door frame shall be 2.00mrn, 1.80mm, and 1.50mm respectively for the B, C and D grades for anti-theft security. The thickness of the outer panel and inner panel of the door leaf is expressed in the form of "outer panel/inner panel", and the levels of the B, C, and D are classified according to security. Select 1.00 mm/1.OO mm, 0.80 mm/0.80 mm, 0.80 mm/0.6 mm. General home security doors are mainly grade C and D. The higher the grade, the higher the anti-theft performance.
Anti-theft door lock standard
In addition to the door itself, the door lock is also the key to anti-theft, the country will be classified into three levels of anti-theft door lock cylinder:
Grade A is the most primitive and unsafe lock core. The owner’s key is flat. There is only one single row of bullet slots. Some cross keys also belong to Class A. Such a lock can be opened in about two or three minutes. Faster.
Class B is a safer class. From the point of view of the key, it is a double-sided double-row bullet bay. If there is a tool for such a lock, the skilled worker must open it for about 10 minutes.
Super B-level lock is currently the safest level, from the perspective of the general double-sided double-row bullet slots, there is a blade or curve next to it, so that the lock cylinder design technical standards to open more than 280 minutes, the general skilled master of the lock also It takes a few hours.
Security door classification
1 , than the thickness
The thickness of the steel plate determines the impact resistance. The thickness of the door frame cold-rolled steel plate: A, B, B, and D are 2 mm, 2-1.8 mm, 1.8-1.5 mm, and 1.5 mm, respectively. Thickness of door leaf outer panel: Grades A, B, and B are 1 mm, 1 mm, 0.8 mm and 0.8 mm, respectively. Thickness of the inner panel of the door leaf: Grades A, B, and B were 1 mm, 1-0.8 mm, 0.8 mm and 0.6 mm, respectively.
2 , than the filler
The State requires that the worst security doors should be filled with honeycomb paper. The Grade A doors are different according to the brand. Some are aluminum silicate rock wool (fireproof cotton), some are aviation honeycomb aluminum, and others are aluminum foil. Class A security doors are usually made of aluminum silicate wool and aluminum foil. Aluminum silicate rock wool has very good heat preservation, fireproof and sound insulation properties. Aluminum foil is light weight, corrosion resistant, non-toxic and odorless, with good thermal conductivity, heat resistance and low temperature resistance. Under normal circumstances, grade B anti-theft door is selected rock wool and polyurethane foam. The advantage of rock wool is that it has good flame retardancy and is a poor conductor of heat.
Polyurethane foam is filled with no gaps and the adhesive is strong after curing. Shock resistance, no cracking after curing, no corrosion, no shedding, ultra-low temperature thermal conductivity, heat-resistant. Highly efficient insulation, soundproofing, waterproof and moisture proof after curing. In the general market of C- and D-grade filling, honeycomb paper is used, and there is basically no insulation, fireproof, and sound-insulating properties.
3 , than the lock
Anti-theft lock is the most important part of the door, and the performance of the anti-theft lock is directly related to the security of the door. The anti-theft door produced by regular manufacturers will have a “security level imprint†in the top left corner of the door. Class A anti-theft door locks have a B-class anti-theft rating, which is an advanced protection class; while B, C, and D-class anti-theft doors, their locks have an A-class anti-theft rating, which is an ordinary protection class. The tamper-proof time is obviously different because of different levels. Grade A is not less than 30 minutes, Grade B is not less than 15 minutes, Grade C is not less than 10 minutes, and Grade D is not less than 6 minutes. At the same time, observe the number of lock points between the door frame and the door leaf. The security doors of Class A, B, C, and D should be no less than 12, 10, 8 and 6 respectively.
Buy "security door" to see the new national standard
In addition to the requirements of national standards for security doors in addition to door panels, anti-theft alarm locks are also required, Class A security doors require the installation of a Class B mechanical anti-theft alarm lock (GA/T73) standards or in line with (GA/374) standards Class B electronic anti-theft alarm lock. Class B, C, and D security doors require the installation of Class A mechanical anti-theft alarm locks (GA/T73) or Class A electronic anti-theft alarm locks (GA/374).
For the various types of anti-theft doors on the market, experts in the technical defense department reminded consumers to pay attention to the new national standard when purchasing security doors to avoid being deceived:
First, it is necessary to inspect the anti-theft security door inspection report provided by the operator or a valid copy or photocopy, and the inspection result should conform to the new national standard.
Second, consumers should pay attention to the three signs when they purchase security doors: security door security code (FAM), security security level ("J", "Y", "B", "D") and corporate custom features, with a dash between the tags connection. Anti-theft security doors that meet national standards have permanent security level markings in the doors.
Third, we must distinguish the difference between security doors and ordinary metal doors. When making purchases, the operator is required to indicate “security door†in the product name column to prevent illegal operators from using steel doors, protective doors, and flood control doors to impersonate security doors; remember to ask for invoices, warranty cards and other vouchers.
The above is the state's newly issued national standards for anti-theft doors, and we hope to help you buy anti-theft doors. For more information on security doors, please continue to pay attention to information on this site.
