What is typically required for security doors instead of loose-pin butt hinges?

Fixed pin hinges are essential for security doors because they provide a more robust and tamper-resistant installation compared to loose-pin butt hinges. Unlike loose-pin hinges, which can be easily disassembled by removing the pins, fixed pin hinges secure the door in place and prevent unauthorized removal. This is crucial for security applications, where the stability and resistance to forced entry are paramount. Fixed pin hinges are designed to maintain the integrity of the door and frame, ensuring that any force applied to the door does not easily compromise its security.

In contrast, concealed hinges often offer aesthetic benefits but may not provide the same level of security as fixed pin hinges. Spring-loaded hinges are essential for doors that need to close automatically, such as fire doors, but they do not specifically enhance security features. Exterior hinges can be used in various applications but may not offer the same security benefits as fixed pin hinges in high-security contexts. Therefore, for security doors, the implementation of fixed pin hinges is a standard practice to enhance durability and safety.
