Composite door systems are provided for use in a protective barrier structure. The composite door systems provide for quick assembly, safety, security, and resistance to physical impacts or threats. The composite door systems may include a shell and a core that can be factory completed or finished on site. The shell may be shipped to the assembly location of the barrier structure, and the core may be formed on site by pouring liquid fill material into a cavity of the shell, which is allowed to cure into a solid fill material. Hardware housings may be operatively coupled to the shell that are made to receive door hardware but resist the liquid full material from filling the hardware housings. The shell, core, and/or hardware housings may provide resistance to damage, such as projectiles to provide enhanced security protection to the occupants or contents of the building structure.

A security screen assembly for a door or window is disclosed herein. The assembly includes a frame with a reinforced lip, a mesh, a plastic insulator to insulate the frame from the mesh and a retaining wedge to hold the mesh in the frame. The characterising feature is that the mesh has cut and punched indentations which abut against the reinforced lip within the plastic insulator to prevent the mesh being withdrawn from the frame once the retaining wedge is in place.

A sliding door system and method is used in an enclosure that defines an inner area shielded against a High-Altitude Electromagnetic Pulse (“HEMP”). The HEMP shielded sliding door system includes an RF shielding door frame, an RF shielding door leaf mounted within an mechanical door leaf frame, a mechanical insertion and retraction assembly attached to both the mechanical door leaf frame and RF shielding door leaf and that operates to extend and retract the RF shielding door leaf into and out of the RF shielding door frame, a drive tube assembly operable to interact with and open and close mechanical door leaf frame (along with RF shielding door leaf) in a sliding motion, and a control assembly, including motor and an air regulator assembly. HEMP shielding air seals are activated when the RF shielding door leaf is inserted into the RF shielding door frame.

A metal door includes a pair of sheet metal door panels. Each of the door panels includes a central body portion with top, bottom and opposing side edges. The doors include an integral flange along each side edge of each panel. The integral flange extends generally perpendicular to the central body portion. An integral inturned lip can be located along each flange and extend substantially parallel to the central body portion. The door panels are positioned such that the central body portions are in an opposing spaced apart relation to one another with the flanges adjacent to and aligned with one another. The inturned lips are positioned in contacting face-to-face relation. The metal door also includes an elongate connector overlying and clamping together each face-to-face pair of inturned lips to maintain the door panels in assembled relation.

A method of making a door involves providing a first door facing including a first raised region and a first panel recessed from the first raised region by a first dimension, and securing a first core insert having a thickness equal to the first dimension to the first raised region. A second door facing including a second raised region and a second panel recessed from the second raised region by a second dimension is provided. A second core insert having a thickness equal to the second dimension is secured to the second raised region. A central core component is secured to the first panel and the first core insert after the first core insert has been secured to the first raised region. The second panel and the second core insert are secured to the central core component after the second core insert has been secured to the second raised region.

Provided herein is a security door system having a door that includes a door frame comprising elongate door frame members, each having a first holding channel formed therein, and a clamping portion spaced from the first holding channel. The door further includes a mesh covering an opening enclosed by the frame. In addition to the above, the security door system includes a wall frame comprising elongate wall frame members operably coupled to the door frame by one or more hinge members, the hinge members facilitating pivotable movement of the door between open and closed positions and one or a plurality of security members configured to prevent or inhibit levering of the door relative to the wall frame.

This invention relates to doors having internal blocking components that reduce or eliminate telegraphing of the outer surface of the door facings. In particular, the invention relates to steel-edge steel doors that have internal solid wood blocks that have one or more integral cantilever beams formed into the blocks to interact with the adjoined oppositely arranged door facings in order to eliminate visually apparent door telegraphing. The blocks are modified to contain notches formed therein to form the cantilever beams.
