Anonymous users2024-01-24Is it a D-level security door?
Generally, Class A security doors will use bright hinges, and Class B also has some brands, but Class C and D regular security doors will not use open hinges.
B-C D anti-theft door will generally use a hidden hinge, because the anti-theft structure of the door is also different from the door of the door, and the anti-vandal opening can not reach the time of the first grade, so the dark hinge is used to prevent the destructive opening from affecting the security.
The price is not determined by hinges, but by the anti-theft level of lock technology
