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.

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.

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.

A vehicle door leaf frame, in particular a rail vehicle door leaf frame, preferably for an inwardly opening vehicle door leaf for an entry door. The vehicle door leaf frame has a plurality of, in particular precisely four, hollow frame profiles constituting the actual vehicle door leaf frame. The hollow frame profiles are produced from a plurality of, in particular precisely two, different hollow profiles. In an alternative embodiment, a vehicle door leaf, in particular a rail vehicle door leaf, preferably an inwardly opening vehicle door leaf for an entry door, has a vehicle door leaf frame and is itself pressure-tight and/or water-tight.

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.

This door assembly (29) comprises a frame (31), extending along a frame plane (P1) and comprising: at least one frame beam (35) defining a frame axis (X35) along the frame plane, the frame beam comprising a main body (39) elongated along the frame axis and having a substantially constant cross-section (S39) along said frame axis, the main body comprising a beveled portion (55) inclined relative to the frame plane; and a swing door (33), pivotably secured to the frame between an opened position and a closed position, said swing door comprising at least one edge beam (63) comprising a main body (139) elongated along an edge axis (X63) of the edge beam and having a substantially constant cross-section (S139) along said edge axis, the main body comprising a beveled portion (155) which is brought to rest against the beveled portion of the frame beam when the swing door is brought to the closed position, wherein the cross-section (S39) of the main body (39) of the frame beam (35) is identical to the cross-section (S139) of the main body (139) of the edge beam (63).
