Swinging Munitions Storage Mobile

Unfortunately, the majority of these doors
have been installed in locations that
strictly prohibit photography, so we only
have a couple of pictures of this style of
door during construction.

Flexibility:
Our swinging blast door systems can be
designed to meet your specific
requirements. Having built swinging blast
doors to over 12' tall and 25' in width, we
are confident that we can build a system
that will meet your requirements or your
imagination.

Design:
Doors are designed using CAD and
structural engineering sotware. Door
frame structure and connection designs
are certified by an independant engineer.
Door frames are engineered using
structural steel memebrs per AISC. Blast
loads are calculated using U.S. Army
Corp of Engineers supplied software to
ensure accurate blast loading and design
compliance. Wind loads, if a factor, are
calculated using your location and
building size for the most accurate
structural loading possible. We don't
make an assumption on the wind load by
using an arbitrary standard, we check
every time.

Construction:
Door components are manufactured to
the highest standards and designed to
be completely bolt together, avoiding
costly delays due to welding inspections
and the availability of certified welders in
the field. Door components are also
designed to have as few connections as
possible, simplifying and increasing
assembly speed on the job. This lowers
the total installed cost for your door
system.

Hinges:
Our hinges brackets are machined in
house to tight tolerances to accept
bronze bushings or tapered roller
bearings, depending on project and
customer requirements. Hinge pins are
drilled and tapped for grease fittings for
ease of maintenance and long life.

Lock System:
Lock systems are machined inhouse to
tight tolerances to ensure proper fit and
function. Lock brackets are fully
assembled, greased and tested before
shipping. In most cases the doors are
assembled onto the door frames and
locked in the closed position. Spacers
are inserted into the door jamb and tack
welded into place. This holds the entire
door/frame package square and straight
during shipping and installation. After
installed simply grind off the tack welds
and remove the spacers. Your door will
be properly aligned and functioning.

Weatherstrip:
Weatherstrip is 1/8" cloth inserted epdm.
Weatherstrip meets military
specifications for durometer, UV
resistance and incidental exposure to
paint thinners. Retainer bar is fastened
by zinc coated self drilling screws every
8" for a secure seal without oil canning of
retainer bar. Retainer bar is easily
removed for replacement of
weatherstripping if it becomes
necessary. Leading edge bubble seals
alow for 4" of compression.

Standard options:
Hydraulic drive operating system, hot dip
galvanizing for brackets, cold zinc

Please call with your custom option
requirements, we are here to create the
system that meets your needs and your
imagination.
