Hello,
Thank you for reaching out to the Hilti Fire Protection Design Team to assist you with your firestop engineering needs.
Unfortunately, we do not have a system for this application. All of our existing systems are for wood framed walls meeting the roof/ceiling assembly. Since you have a steel stud wall, this would need to be an Engineering Judgment which will be a custom detail showing your exact application with the firestop components required to maintain the stated ratings.
Hilti is proud to announce the launch of our engineering website, the HILTI CONSTRUCTION PLATFORM (HCP). This platform will be the home for all of your Fire Protection Engineering needs, including Engineering Judgment requests. You can find more information on how to access this new platform here: https://www.hilti.com/ej (US) or https://www.hilti.ca/ej (Canada.)
Along with HCP, Hilti is excited to announce our new mobile app for all your firestop needs: Hilti Firestop Selector. Using the Firestop Selector app gives you easy access to the Hilti Fire Protection Design Team from the jobsite, on the road, or in the office to request a new EJ, an EJ Revision, or ask a Question anytime, anywhere.
If you have any questions, please reach out to our customer service team at 1-800-879-8000 (US) or 1-800-363-4458 (Canada) for assistance.
Thank you,
Jessica Starks
