The prime function of a door frame is to hold the door and its controls in the opening, and to trim the opening. Frames also will often serve as other esthetic or functional purposes such as trimming a wall opening having no door. Hollow metal frames are strong sturdy and durable and serve all functions economically.
HMI machinery will allow a wide variety of configurations of hollow metal frames. Shown below are just some of the frame types
