Anonymous users2024-01-21Hello landlord, I am Xiao Li, the dealer of Inner Mongolia Baotou Xingyueshen security door! The question you raised, I have a little bit of my own opinion, please share! The level of the anti-theft door is related to many factors, the key you described is only one of the factors, the most direct factor is the thickness of the steel plate used in the door frame and the door panel, the door frame of the Grade A door, the B, C, and D gradually decreasing, of course, it is also related to the lock body, lock cylinder, handle, and door anti-theft structure!
