ViperStud®
ViperStud® is a high-performance drywall framing system engineered for strength, ease of installation, and compatibility with conventional flat steel framing components.
A High Strength, Flat Steel Drywall Framing System
The ViperStud Drywall Framing System is designed to replace conventional flat steel studs, delivering exceptional performance without compromising on the familiar benefit.
Installation is the same as conventional studs, eliminating the need for additional training or specialized fasteners, streamlining your installation process and reducing overall expenses.
Additionally, the ViperStud drywall framing system is interchangeable with conventional framing components and the flat steel design ensures effortless plumbing, marking, and adjustments, making it compatible with your existing tools and techniques.
- Lighter, stronger, and more efficient framing system for better handling
- Interchangeable with conventional framing components for installation flexibility
- No extra training or special fasteners required for installation
- Knurl & rib technology adds strength and improves screw performance
- One-track system (ViperTrack25) simplifies material selection and inventory
ViperStud has been verified by Intertek as code compliant to the following codes: IBC 2015, 2018, 2021, and FBC 2020.
ViperStud is tested or conforms to these standards:
- ASTM A1003, C645, C754, E90, E119, E72, C1629
- AISI S220, S100-16/S2-20
ViperStud® is listed in the following:
- Intertek CCRR-0154
- NYC Department of Buildings MEA 56-08-M, MEA 56-08-M Vol 2, MEA 235-08-M
The stud and track system utilizes a knurled flange and reinforcing ribs along with a flat stud design.
Knurling is the pattern of small ridges formed on the flange to prevent screws from walking. Since knurling is only formed on one side of the steel, the stud stays flat, never compromising the strength or thickness of the steel.
ViperRib® technology applies a reinforced ribbing over the web and flange of ViperStud. The ribs provide added strength, are less prone to twist and creating ”high-shoulders” when finishing gypsum board.
ViperTrack25 has been extensively tested with Viper25 and Viper20 studs. Our third-party testing proves that it is not necessary to use the same thickness track as the stud. Now you can submit a lighter gauge track with your Viper20 studs and reduce your cost.
- Saves money
- Fewer items to inventory
- Safer, ViperTrack25 is fully hemmed
- Supported by testing
Not applicable for Impact or Abuse Rated walls. Fire rated walls should be built per specific assembly requirements.
