New Patent-Pending Concealed Fastener Clip from Metl-Span Increases Strength, Durability of Building Facades

Publish Date: Wednesday, July 20, 2022

LEWISVILLE, Texas, July 20, 2022Metl-Span, a recognized leader in the advancement of insulated metal panel technology, is expanding its lineup of clips for concealed fasteners with the introduction of the patent-pending V6 X-Span Clip.

The V6 X-Span clip provides an alternative to backfastening, allowing crews to install longer spans without the need to access the interior of the panel for a more efficient installation and stronger panel.

The V-shaped fastener is designed to fit the joinery of Metl-Span CF insulated metal panels to increase the stiffness of the panel and better distribute the shear load at fastening locations. This distribution helps to delay panel disengagement under negative loads, a failure point of thicker panels at longer spans.

“The V6 X-Span Clip introduces material, labor, and time savings for installation crews for long span building envelopes utilizing Metl-Span insulated metal panels,” said Jennifer Franz, product manager at Metl-Span. “This clip advances efficient design to better serve the industry and delivers greater long-term durability.”

The V6 X-Span Clip can be combined with face-to-clip fasteners at end supports to further delay disengagement and allow for even larger negative wind loads or longer spans. The same clip and face-to-clip fastener are used regardless of panel thickness, minimizing the number and variability of components.

Additionally, the V6 X-Span Clip is reversible with holes at the ends of the clip and at the center for intermediate supports, negating the need for two different clips to be used at different areas or for field-drilling holes in the clip.
