What is the difference between interior door security level A and Class A

Interior doors are home doors, mainly wooden doors. There are many differences with the outdoor (entrance door) - security doors and security doors, and there are also differences in terms of safety requirements and materials. There is no corresponding safety level standard requirement for interior doors, so the escort decoration network believes that the safety level of interior doors should be understood according to the level of entry anti-theft doors and security doors

The anti-theft level of household doors is divided into: A, B, C, D four levels. Specifically, the thickness of the plate:

Class A, B, C, D are 2 mm, mm, mm and mm, respectively; The thickness of the outer plate of the door leaf: A, B, C and D are 1 mm, 1 mm, mm and mm respectively; The thickness of the inner plate of the fan: A, B, C, and D are 1 mm, mm, mm and mm respectively.

The division of A-level is mainly based on the door lock, and the lock cylinder of the anti-theft door lock is divided into three levels:

1. Class A is the most primitive and most unsafe lock cylinder, the owner's key is flat, only a single-sided single-row slot, and some cross keys are also Class A.

2. Grade B is a safer level, and it is a double-sided double-row bullet groove from the key.

3. Super B level, which is the safest level at present, from the key to see the general double-sided double-row slot, there is a blade or curve next to it.
