Strongwell Receives L.A.R.R. Approval for Use in RF Transparent Screening and Enclosure Systems

Strongwell's fiberglass structural materials are the clear choice for rooftop communication antenna screening and cellular shielding applications because the RF transparent materials are now certified by the Los Angeles Research Report, L.A.R.R., for use in RF transparent screening and enclosure systems. The L.A.R.R. requires exceedingly difficult 3rd party tests, against a very stringent list of mechanical, fire, UV and weathering ASTM standards. In addition to rooftop screening, the safety factors of the approval allows Strongwell’s structures to be placed on anything from the top of skyscrapers, trellises, architectural treatments on the sides of buildings, to bus-stops.

Strongwell’s L.A.R.R. approval is the most comprehensive in the industry, approving EXTREN® structural shapes and plate, DURASHIELD® building panels, SAFPLANK® interlocking planks and FIBREBOLT® studs and nuts for cellular and RF applications.

L.A.R.R.-approved fiberglass structural materials are:

  • Transparent to Cellular Emissions / Frequencies
  • Lightweight
  • Corrosion / Rot Resistant
  • Virtually Maintenance-Free
  • Durable / Impact Resistant
  • Attractive

One application, shown right, incorporated four 35´ high x 35´ square fiberglass turrets atop the Sun Bank Building in Orlando, Florida, giving the massive building a sleek and elegant "peak of distinction" while serving a vital and practical purpose. Originally conceived as steel and aluminum decorations, the fiberglass turrets of EXTREN® structural shapes house 20´ high antennae for police and fire communications. Unlike steel, FRP's RFI/EMI transparent properties allow radio signals to pass through fiberglass. In addition, the turrets were specifically designed to accommodate hurricane winds common in Florida.
