The answer to this question varies with the load direction, the seam profile, the roof material and the clamp model. We have done hundreds of tensile load tests parallel to the panel seam and on various gauges and profiles, we have tabulated the results for your convenience. See the 'Load Test Results' tab for that information. Also, use the "more info" button for a complete description of the testing performed. In this load direction any loads that are introduced into the clamp will accumulate into the point of fixity. Panels must be adequately attached to resist these loads.
