ProSTUD® Drywall Framing System

Steel Drywall Studs with smart edge™ technology

ProSTUD Drywall Framing System (ProSTUD® and ProTRAK®) with Smart Edge™ Technology is the innovative steel drywall stud that sets a new industry benchmark for high performance. Its patented 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 and 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. ProSTUD is available nationwide.

Technical Data: 

WHICH PROSTUD® LIMITING HEIGHT TABLES SHOULD I USE?

ProSTUD, like any interior drywall stud, may be used in a variety of applications including walls, ceilings, and soffits. While some conditions may require the expertise of a design professional, many assemblies can be selected based on tabulated data. Locate the required assembly below and follow the instructions for selecting the proper ProSTUD member.

In addition, iProSTUD 2.0 provides direct links to UL design reports, third-party STC sound tests and SubmittalPro®, where contractors can view technical data sheets and generate submittals.

Launched in 2013, ClarkDietrich iTools was developed to help architects and contractors evaluate purchasing decisions and assist in product selection for steel framing projects. The cost-saving calculators use applicable project data to give an instant comparative pricing model for both materials and labor for many of ClarkDietrich steel framing products. ClarkDietrich iTools also provides direct links to product pages, LEED® request forms, product literature and technical data sheets. ClarkDietrich iTools is available in both desktop and mobile formats at iTools.clarkdietrich.com.

COMPOSITE ASSEMBLIES

Composite limiting height data can be applied to walls where gypsum board is installed on both flanges of the stud for the full height of the wall. ProSTUD® composite data is based on the 2015 International Building Code, and was tested and analyzed in accordance with the most recent version of AC86 (2015).

NON-COMPOSITE ASSEMBLIES

Non-composite conditions are common in all structures. When the gypsum board stops at the ceiling level, but the stud continues to the deck, it is a non-composite condition. While there may be advantages to contacting Technical Services or a Design Professional, many conditions can be covered by limiting heights tables shown below. When in doubt, call our complimentary Technical Services Hotline at 888-437-3244.

Distance of unbraced length (Lu) can be found in ProSTUD® Physical and Structural Properties.

CEILING SPAN TABLES:

Interior ceilings are often supported by ProSTUD® framing. The design criteria varies greatly based on the weight of the ceiling, bracing, and support points.

CHASE WALLS OR FURRED WALLS

Chase & furred walls are common, but the conditions vary greatly depending on the building requirements.

  • While non-composite tables may be used conservatively, when in doubt, contact our Technical Services Hotline at 888-437-3244 for chase wall designs.

 


Installation: 

ProSTUD® Allowable screw design values (lb.)

Table Notes:

  • Allowable screw connection capacities are based on Section E4 of the AISI S100-12 Specification.
  • When connecting materials of different steel thicknesses or tensile strengths, use the lowest values. Tabulated values assume two sheets of equal thickness are connected.
  • Screw shear and tension capacities were developed using published screw manufacturer data and evaluation reports available at the time of publication.
  • Screw capacities are based on Allowable Strength Design (ASD) and include a safety factor of 3.0.
  • When multiple fasteners are used, screws are assumed to have a center-to-center spacing of at least three times the nominal diameter (d).
  • Screws are assumed to have a center-of-screw to edge-of-steel dimension of at least 1-1/2 times the nominal diameter (d) of the screw.
  • Tension capacity is based on the lesser of pullout capacity in sheet closest to screw tip, or pullover capacity for sheet closest to screw head (using head diameter).
  • Screw capacities are governed by a conservative estimate of screw capacity, not by sheet steel failure.
  • For higher screw capacities, especially for screw strength, use specific screws from specific manufacturer. See manufacturer’s data for specific allowable values and installation instructions
     

 

ProSTUD® Deep Leg Deflection Track Systems

Head-of-wall vertical deep leg deflection track systems are required to allow the top of the wall stud to float within the top track legs. This connection allows for vertical live load movement of the primary structure without transferring axial loads to the interior drywall studs. A gap (determined by the Engineer of Record) is required between the top of the wall stud and the deflection track.

ProSTUD Drywall Framing studs can be used with multiple Deep Leg Track Systems:

  • ProTRAK® Deep Leg Track
  • Structural Deep Leg Track (18ga. & 16ga.)
  • MaxTrak™ Slotted Deflection Track
