Steel Welded & Knockdown Frames
Welded steel frames are press brake formed true. Jamb and head section are assembled with a tongue and groove arrangement with miters accurately fitted, fully welded and ground smooth. All frames are accurately mortised for hinge and strike plates according to hardware specifications. Masonry and drywall anchors are attached as required.
Knockdown frames are constructed with integral tabs that can lock together, as well as compression tabs to lock the frames to the drywall. The tab design prohibits the frame head from rising and keeps all members aligned.
Reinforcement is provided with steel plates that are welded to the frame, precisely drilled and tapped to accommodate template hardware. Reinforcements are also provided as required for door closers, hinges, locks, and any other door hardware.
Frames can be punched and dimpled for easy installation.
