    Overview

    About Security Frames

    Security frames are heavy-gauge hollow metal frames with added reinforcement. They are specified for correctional facilities, data centers, banks, evidence rooms, pharmacies and restricted government spaces.

    The extra steel, anchoring and reinforcement help keep the frame from being spread or pried away from the door, and the frame is prepared for the heavier hinges and locks a secure opening uses.

    A security frame performs only as well as the door and hardware installed with it, so Mills & Nebraska coordinates all three as one assembly.

    How to choose

    Define the forced-entry level, hinge and lock preps, anchoring and any fire rating up front, because changes after fabrication are difficult on heavy-gauge frames.

    What security standards apply to security door frames?

    Forced-entry resistance for door and frame assemblies is commonly tested to ASTM F3038. Mills & Nebraska works with Florida correctional facilities, banks, and government agencies to supply security frames at the protection level the specification requires.

    Can security frames also be fire-rated?

    Yes. Many secure openings need both forced-entry resistance and fire protection. The frame, door and hardware must each carry the required fire label or listing, so the security features have to be part of the rated assembly rather than added afterward.
