Can S-5 clamps be used on on 26 guage standing seam metal roofs? Thanks for any assistance with this questions.

yes, they can. Follow directions on the S-5! web site. Most manufacturers alos offer instructions.

I should stress that these work on "double lock" or mechanically seamed panels. Do not use these clamps on a snap lock product.

I have seen them successfully used on snap lock panels. Todd Miller

Todd, Would you mind posting a picture of the snap lock profile that you have seen successfully used with S-5 clamps? The problems I have seen are typically associated to the air gap that snap lock profiles carry. The clamp pushes the seam and damages the snap connection from personal experience.

They have been used for several years now on our Ultra-Dek panel which is a snap lock panel. We have tested them in our ASTM E1592 chamber and the panels have a significantly higher wind uplift with the clamps. Our load tables, reflecting this, on are on our web site.

Ken, Thanks for the response. Very interesting. At 140 lbs of torque, have you not experienced any damage to the panels? From what I read, it sounds that your company was using the clamp to provide a higher wind rating, is that the case? I will have to grab a sample next time I run by the location close to us and give this a try. Thanks

You are correct Kurtis. We had a "wind clamp" specially designed for our panel and did a complete series of tests to create load tables. This gives the roofing contractor a way to meet the higher pressures in the edge and corner zones without having to decrease the clip spacing in many instances. We have also been using the standard S-5! clamps on these panels for a number of years. AS to damage, there is a slight dent in the seam where the set screw tights onto it. However, this is not visible unless you take the clamp off for some reason and even then is usually not able to be seen from a few feet away. It does not affect the integrity of the seam.

If you are tightening the set screws on your S-5 clamps to 140 lbs of torque, its no wonder you're experiencing damaged panel seams. S-5! recommends a torque value typically between 115 and 180 "inch" lbs. W

You have to use the s-5 mini clamp on some snaplock profiles.
