Universal Shielding Corp.
(USC) was established in 1972 and during this time span has provided in excess of
modular RF shielded enclosures to military, commercial and medical
facilities. USC is proud to be the only company in the industry to have maintained its original ownership since its inception.
Universal Shielding Corp. is the second largest RF shielding
manufacturer in the United States.
Enclosures meet TEMPEST and
specifications NSA-65-5, NSA-94-106
USC designs, manufactures, installs, and
tests its RF shielded enclosures nationally and internationally.
USC's reliability, scope and quality of
their services have earned them a well deserved reputation.
Enclosures have been approved by all MRI and EMC/RF
Universal Shielding's USC-26 RFI/EMI shielding
system is designed to meet or exceed the vast majority of shielding
requirements. This system is available in both standard modular
enclosures and custom-designed modular enclosures to meet exacting
specifications in government, industry, research and development,
university or hospital use. Rigid, steel-clad, 4-foot structural
panels with steel framing form the modular USC-26 RF shielded
enclosures. Weld-nuts on the corner and intermediate framing members
eliminate screws that penetrate the framing members. In addition,
this exclusive weld-nut feature provides a structure that is
tamper-proof from the outside... an important consideration in
Secure Communications. Our enclosures can be designed to accommodate
raised floors for computer installations, suspended ceilings with
recessed lighting, and specially-designed channels for installing
acoustic and/or anechoic absorbers. To the right is a typical
performance curve for the USC-26 shielded enclosure when tested in
accordance with MIL-STD-285 or IEEE 299. Will meet NSA 94-106 and NSA 65-6
Both USC-26 and USC-44 series panels are
interconnected with a framing system to form the enclosure.
Enclosures are completely erected from
interior and thus can be placed in proximity to parent room
Can be dismantled, transported, re-erected,
and still maintain their attenuation capabilities.
Parts are all numbered to enable customer to
install chamber rapidly.
DESIGN ADVANTAGES OF UNIVERSAL
All four shapes of channel members have serrations running
lengthwise along each side of the contacting surface where
it mates with the panel, thus resulting in a highly
efficient RF seal.
Our clamping system consists of weld-nuts welded to the
outer framing member on Three (3) inch centers. Thus NO
screws penetrate through the enclosure. There are no
opposing joints between the periphery M' and U channel
members at any point.
Our integral "flat" channel has a convex contour for
positive spring tension, insuring an RF tight enclosure.
Our corners are an all-welded one piece assembly consisting
of three (3) 15 inch long members.
The entire steel framework is supplied with integral
interconnecting tabs and weld-screws and is assembled from
the interior. This system enables rapid assembly and
positive placement of channels resulting in no voids or
separations in channel system, thus preventing RF leaks.
Our doors incorporate a brass extrusion around door and
frame. These extrusions are designed so that the contacting
fingerstock is not exposed, thus resulting in a damage-free
closure seal. The fingerstock is not held in place with any
mechanical or solder methods and is easily removable.
All channel members are metal-stamped for identification and
their designations are indicated on installation drawings,
thus enabling rapid assembly.
Our RF air vents are mechanically held in place with all
welded frames, thus enabling honeycomb vent to be easily
removed for cleaning after long periods of usage.
A filet weld is factory installed at end of each "hat"
section so that NO gaps exist at intersection of "hat" and M

values are expressed in logarithmic, not linear, terms. Therefore, 80 dB
of shielding effectiveness is not double the 40 dB level, but 100 times
greater. Another way to express effectiveness is attenuation ratio,
which compares the attenuation signal strength outside and inside the
shield as shown below.

Building code maps
using numbered zones, 0, 1, 2, 3, 4, are practically obsolete. 1969 was the
last year such a map was put out by this staff.
The 1997 Uniform
Building Code (UBC) (published in California) is the only building code that
still uses such zones.
the past two decades, building codes have replaced maps having numbered
zones with maps showing contours of design ground motion. These maps in turn
have been derived from probabilistic ground motion maps. Probabilistic
ground motion maps have been included in the seismic provisions of the most
recent U.S. model building codes, such as the new "International Building
code," and in national standards such as "Minimum Design Loads for Buildings
and Other Structures," prepared by the American Society of Structural
