The application discloses a hangar door assembly construction method, comprising the following steps: step 1, site access preparation, site construction operation surface partition; step 2, installing an upper rail system at the top of a door opening of the hangar door and installing a lower rail system at the bottom of the door opening; step 3, assembling a door body framework on the site construction operation surface; step 4, hoisting the door body framework; step 5, installing a panel, edge closing, driving and electrical systems, and completing installation of the hangar door; and step 6, running and debugging the hangar door. The application relates to the technical field of steel structure construction, and can solve the problems of large work load and high safety risk of high-altitude assembly of a hangar door in the prior art.

A window security system can include a frame assembly including a plurality of segments. Each segment can have a first end and a second end and a central channel extending longitudinally between the first end and the second end. The central channel of at least one segment can receive a member for protecting a window. The window security system can include a connector hingedly coupling the frame assembly to a window frame of the window. The window security system can include a housing defined within a segment of the frame assembly. The housing can include a lock having an actuator coupled to a bolt. The lock can couple the frame assembly to the window frame in a locked position, where the actuator can drive the bolt into a recess defined in the window frame to position the member for protecting the window.
