Monarch engaged Qualtim, Inc. of Madison, Wisconsin to undertake load testing of the Monarch Z Clip system for mounting panels in the most typical installations. The tests included testing of the panel clips to the back of the panel, testing of the Monarch Clip system in a typical installation on metal studs and wood studs.
The testing confirmed what Monarch had informally tested years ago. First, that in a typical installation of a four-foot-by-eight-foot and ¾-inch thick MDF panel that the tested failure of the system is 30 to 40x the weight of the panel. Second, that the mode of failure is not he Monarch Clip itself, but rather the pull out or shearing of the screw selected to secure the Monarch Clips.
The results of the test are available for download on the z clip specifications page at the Monarch Web site, in addition to a full summary of the Monarch Z Clip load–shear testing and a Monarch Z Clip weight capacity summary sheet showing the average load failure for a variety of installation circumstances.
“We are pleased to be able to offer the results of these tests conducted by a 3rd party independent laboratory,” said Chris Smith of Monarch Metal. “We had for years shared the results of our internal testing, but it is nice to be able to offer our customers something more formal.”
