Handling High Wind Uplift and Edge/Corner Zones

Stricter high wind uplift and edge/corner zone rules continue to challenge metal standing seam roofing systems throughout the building industry today.

Stricter high wind uplift and edge/corner zone rules continue to challenge metal standing seam roofing systems throughout the building industry today.  These stringent high wind edge/corner zone mandates are quickly spreading and being enacted by cities, counties, states and provinces across the US and Canada at a record pace for many projects utilizing building designs with  metal standing seam roofing systems. Many companies, architects, spec writers and owners are searching for possible solutions to accommodate these harsher performance code requirements.
Utilizing our proprietary Superior Seam Technology™ (SST) to overcome such obstacles for successful project metal roofing systems outcomes, these areas of design concern have confidently been addressed by Building Research Systems, Inc (BRS). High wind uplift and edge/corner zone challenges have been subjected to constant developmental review for innovative solutions at our facility. The SST Research and Development team have created, patented, and tested benchmark setting innovations that are specifically designed to handle the stricter high wind uplift and/or edge/corner zone code performance requirements.  


The BRS TS-324® and the Panel Craft 216/218 metal standing seam roofing systems, both share two industry leading innovations that no other competing industry products can compete with to handle high wind uplift and edge/corner zone requirements. Both patented advances are exclusive to BRS licensees standing seam roofing systems. These advances provide clear technological design advantages over all competitors for wind uplift and edge/corner zone code compliance for enhanced performance. The BRS innovative and established field-tested advancement, designed to handle these stricter mandates, is the UL listed Wind Clips with their extended tabs for connection to the panel seam for maximized load distribution. The TS-324® roof system BA602-8, BA603-8, BA 602-12, BA-603-12 BA602-16 and BA603-16 movable (8”,12” and 16”) wind clips are now listed with UL.
The UL construction numbers associated with the TS-324® wind clips are UL 552, 552A and 552B along with recently “blank sheet” redesigned fixed clips. Panel Craft 216/218 wind clips UL construction numbers are listed under 506, 506A and 506B and offers an extended a 12” tab for panel seam load distribution and maximum seam connectivity.
Another forward-thinking design component developed to handle the building design calculated corner/edge zone and high wind uplift performance mandates is the SST patented High Capacity Rake/ Starter plates. These industry leading components were developed with the future in mind to comply with the current ASCE 7-16 , IBC 2018, and the upcoming more stringent IBC 2021 codes for edge/corner zone wind uplift performance. These high capacity rake parts have the added benefit of handling up to 7” of travel for thermal movement while being independently tested to be approximately 4X stronger for uplift than the current industry standard slotted rake designs. The High Capacity Rake/Starter Plates used in combination with the Wind Clips allows for single panel runs over 500’-0” without over taxing the clips or the up to 7” of available thermal travel of the rake parts.


Late fall of 2020, BRS will be amending its endorsed starter and finish details from clips to the High Capacity Starter Rake /Universal Rake Plates. Both these forward-thinking SST inspired and designed parts are currently available through our strategic partner Logan Stamping in Logansport, IN to all BRS license holders. The High Capacity Universal Rake Start and finish endorsed details can be found on the BRS website in each of the panel profile detail guides.
REMINDER: The RP-038 and RP-138 slotted rake/eave plates tooling will be retired December 31, 2020 and these parts will no longer be available for purchase once all stock inventories are exhausted. BRS recommends that all licensees develop a transition and implementation plan to move to the High Capacity Rake Plates at their earliest opportunity. Please contact BRS if additional assistance is required.
