New Development Greatly Reduces "Whip" Action
During Installation; Also Makes Grid Easier to Cut

LANCASTER, PA -- Armstrong has announced a new "peaked roof" bulb design that dramatically improves the handling of its Suprafine Intermediate Duty Main Beams.

Called "PeakForm™," the new development greatly reduces "whip" action during installation of the popular ceiling suspension system.  It also makes the grid easier to cut, and increases the duty load performance of the Suprafine system.

According to Doug Cadle, Vice President of Global Sales and Marketing for WAVE, the Worthington Armstrong Venture that manufactures the grid systems marketed under the Armstrong brand name, the new PeakForm grid profile is a prime example of responding to market needs.

"The PeakForm design is another in a series of product improvements that have resulted from collaboration with our customers," he says.  "Like hot dipped galvanized steel and rotary stitching, the PeakForm shape is a performance-enhancing feature that benefits both owners and contractors alike."

Suprafine is a 9/16" exposed tee system used in a variety of applications ranging from schools and offices to stores and healthcare facilities.  The new PeakForm Intermediate Duty Main Beam, which measures 12' long x 1-11/16" high, also features a Triple Lock splice that snaps together with an audible "click."

Like all Armstrong main beams, the PeakForm main beam features a hot dipped galvanized coating that inhibits rusting better than electrogalvanized or painted systems.  The main beam is also rotary-stitched during manufacture by a patented method to provide additional torsional strength and extra stability during installation.
