RF Shielded Rooms - Copper Screen

Universal Shielding Corp.

Universal Shielding Corp.

Manufactured and Serviced in Deer Park, NY USA


Universal Shielding Corp. (USC) was established in 1972 and during this time span has provided in excess of 40,000 pre-fabricated  modular RF shielded enclosures to Government, 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.

  • Copper Screen Enclosures are designed to eliminate ambient EMI/RFI inside and contain RF signals from interfering with systems outside.

  • 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.

  • Both USC-26 and USC-44 series panels are interconnected with a framing system to form the enclosure.

  • Enclosures are completely erected from the interior and thus can be placed in proximity to parent room walls.

  • Can be dismantled, transported, re-erected, and still maintain their attenuation capabilities.

  • Parts are all numbered to enable customer to install chamber rapidly.

Framing Drawing





Frames with copper screening adhered to each frame surface. Advantages of this type of construction:


  • Communication easily transmitted between interior and exterior.

  • Special ventilation is not required.

  • VISUAL observations of testing are possible from exterior of enclosure.

  • Upper vertical wall panels and ceiling are copper screen panels.

  • In most cases fire protection sprinklers above the enclosure meet code

Universal RF Shielded Doors


Universal enclosures provide extraordinary shielding attenuation. This is attributed to the shielded enclosure door design

Latching Mechanism

USC enclosure doors are equipped with a 3-point latching mechanism for tight, RFI-EMI-secure closing. Bearing surfaces, rollers and door cams are of case-hardened tool steel, designed to provide years of trouble-free operation with no loss of attenuation capability due to friction and wear. Our doors are extremely easy to operate; they require less than 20 pounds of force on the handle.


Door Construction

To achieve the attenuation levels required, our doors are equipped with a minimum of two rows of beryllium copper "fingers" around the periphery of the door. In the closed position, the fingers contact the door frame to assure an RFI/EMI leak-proof seal. The following is a type of door/frame construction offered by USC:

Model RCM-154 Door design encompasses:

  • Single Knife Edge (MIL-STD-285) 100 dB

  • Concealed finger stock - This design results in a damage free closure seal

  • Three point latch system

  • Three adjustable hinges

  • Standard door clear opening 36" X 84"

  • All sizes are available, single and double doors

  • Optional - Outdoor MIL-STD Approved

Earthquake Zones


Earthquake Zone Map

US Geological Survey, 1997



Universal Shielding Corp. can build your new shielded enclosure to meet any of the earthquake code requirements.


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.

Generally, over 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 Engineers.


Universal Enclosure Shielding Attenuation Characteristics 




Electric/Plane Waves

USC - 26


120dB   120dB   120dB


USC - 44


100dB   100dB    >85dB


These are maximum values with optional components

Shielding effectiveness 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.
