Security door based on desired level of security
A steel security door is basically a reinforced fire door. We offer protective doors in different security classes (SSF class 1, 2, 3). Security doors with different protection classes can be a requirement from different insurance companies but also a security for the property owner and the user. Fireproof, classified and bulletproof doors are also needed at airports and other places where personal safety needs to be extra carefully protected.
