ProSTUD™ Drywall Framing.

It’s here. The innovative ProSTUD Drywall Framing System that sets a new industry benchmark for high performance. Its patent pending design combines high-strength steel with additional stiffening enhancements for a drywall framing stud previously unimagined.

When we set out to develop this revolutionary drywall framing system, we wanted it to be the best. The most innovative. So, we called in the pros – the guys that work with the product day in and day out. ProSTUD Drywall Framing was developed, tested and approved in the field. The result? Drywall framing performance designed by the pros for the pro.

What’s more, ProSTUD Drywall Framing is backed by comprehensive laboratory testing for strength, fire and sound. No other drywall framing system has been as thoroughly tested as ProSTUD. So not only is it a dream to work with, but it also has the performance to meet the requirements of today’s building codes.

 

 

Construction Advantages:

• High strength steel combined with low-profile flange stiffening grooves
  and double offset web planking increases strength and provides greater
  limiting heights
• Diamond embossed web creates stiffness, reducing flange fade and screw
  spinout during drywall installation
• Strong, lightweight stud and track cuts and handles easier than
  conventional flat steel studs
• Flange grooves provide sight line for drywall alignment and aid in
  positioning screws at drywall joint to maintain the 3/8” edge requirement
• Web and leg enhancements in ProTrak™ provide straight and rigid members, making it the best choice for framing walls, headers, soffits, and bulkheads

Design Advantages:

• Designed to meet the additional strength requirements of today’s building
  codes: IBC 2003, 2006 & 2009, AISI NASPEC (S100), ICC-ES AC86 (2010)
• UL Classified with listing in over 40 designs, including V450, U419, V438,
  and chase wall assemblies
• Exceptional sound performance in over 40 tested sound assemblies
• Independent Product Certification:
  IAPMO ES Pending
  ICC-ES Pending
• Can contribute to 7 LEED Credits under LEED for New Construction and
  Major Renovations (LEED-NC Ver. 2.2)
• National availability

What is an Equivalent (EQ)
Drywall Stud?

Gauge equivalent drywall framing must meet the minimum performance requirements of conventional drywall framing. ASTM and AISI define conventional drywall framing studs as basic C-shaped members. These basic members do not take advantage of today’s roll-forming and steel making technologies that enhance the shape and strength with greater efficiency. ProSTUD employs these technologies and exceeds the performance of conventional drywall framing. When comparing drywall framing systems it is important to keep in mind Life Safety, System Performance, and Connections.

life safety

Life Safety is the primary concern and duty of all construction and design professionals. For interior drywall framing members, bending strength is the criteria most important to the strength of a wall or ceiling. The American Iron and Steel Institute (AISI) defines bending or flexural strength by Allowable Moment. The corresponding chart compares the bending strength of ProSTUD and conventional drywall studs.

system performance

Given ProSTUD’s strength and versatility, it is important to know the performance of the ProSTUD under your project’s specific criteria. This catalog along with data at clarkwestern.com will provide guidance in a variety of assemblies and loading criteria, based on current building codes.

connections

In addition to sufficient member strength, it is important to know how connections will perform. Connections can be critical to the capacity and safety of an assembly, but they are also important for attachments of cabinets, shelving, handrails, and other accessories to steel framing. The tables below compare the screw performance of ProSTUD to conventional drywall framing. This performance relationship to conventional studs can be applied to a variety of fasteners and connections.

Along with connection capacity, conventional framing members are required to meet performance criteria for screw spin-out. ProSTUD was developed with screw performance in mind. High-strength steel, flange stiffening grooves, web embossments, and knurling features combine to provide the best performing screw spin-out per thickness, exceeding the requirements of ASTM C645.
