Drake,
For reference, I’d say that we need to pinch/crimp seams on 80% of our standing seam installs in order to get the S5 clamp to fit. As long as some cardboard is used to avoid scratching the galvanized-like coating (Galvalume, for example) we haven’t had any corrosion issues with S5 clamps. I’ve gone back to inspect systems that were installed several years ago in our Bay Area semi-coastal environment and there may be a little bit of rust, but nothing serious. The stainless set screw almost certainly pierces the metal coating but the rust doesn’t get far. This could be a completely different story in an extreme coastal environment like parts of Florida, Hawaii, etc – but then again, I don’t even know if standing seam metal roofs are used in those areas. -August PS: I like the idea of duckbill vise grips! We’ve typically used medium-large channel locks to crimp the seams but I think the duckbill clamp is potentially more elegant. *From:* RE-wrenches [mailto:[email protected]] *On Behalf Of *Drake *Sent:* Friday, August 14, 2015 6:38 AM *To:* RE-wrenches *Subject:* Re: [RE-wrenches] Standing metal seam clamps Why are those better? I'm designing a system for a standing seam roof built by an Amish crew. They likely used a Zimmerman machine to make the roof on site. The seams are triangular shaped measuring 1 1/2" high and 11/16" wide at the base. It looks like we will need to pinch the seams with duckbill vice grips to get the clamp on. Is there a better solution?
