Designing a special screw for our S-5! product lineup was only the beginning. We then conducted ASTM B-117 salt spray weathering tests on panel seam specimens to determine whether these screws caused any damage, however slight, that could result in premature corrosion. After 1,000 hours in the salt chamber, no corrosion was detected at any of the setscrew locations! In fact, S-5! offers the only setscrew-based attachment system on the market that puts neither your roof nor your roof warranties in jeopardy!
We also use the highest quality (18-8) stainless steel alloys for all S-5! hardware, and include auxiliary stainless mounting bolts and washers with each clamp to assure longevity and metallurgic compatibility—no matter what the attachment application.
S-5! attachment technology has been in use on rooftops since 1992. Over the years, it has come to be recognized, recommended and even distributed by leading metal panel manufacturers the world over—many of whom will approve no other method for rooftop ancillary attachment.
Our setscrews are designed to dimple the seam material without puncturing, scratching or harming it.
