ProSTUD Drywall Framing System - FAQs

Is it acceptable to use a 25-gauge track with a 20-gauge stud?

While the published limiting height value charts are focused on the stud values, it is often misunderstood if it is required that the same gauge track be used when selecting from the charts. The charts are actually limited by the stud behavior and not track behavior. In most cases, the stud will likely be limited by deflection or bending of the stud along its span. In some rare cases, the stud’s stress limit is reached. These two cases are based on the stud’s behavior. When you look at each published case and compare the end reactions generated by the combination of lateral pressure, deflection limit, and limiting height, you find that the base reaction is less than the allowed limits for the mating track of a lighter gauge.

Therefore, it is acceptable to use 25-GA EQ ProTRAK® with any 20-GA EQ ProSTUD® published limiting height, wall pressure, and deflection limit. In all published scenarios, the capacity of the 25-GA EQ ProTRAK® exceeds the base reaction of the wall stud at the published height limits. Should you have any questions about a specific case, please call our Technical Services hotline at 1-888-437-3244.

Who developed ProSTUD Drywall Framing?

ProSTUD Drywall Framing was a technical collaboration between the engineers and technical resources at ClarkWestern Building Systems and Dietrich Metal Framing.

Why introduce ProSTUD Drywall Framing?

Since the launch of UltraSTEEL™ in 2006, we have learned a great deal more about "Equivalent” stud technology. ProSTUD was the logical step toward the next generation of drywall framing technology.

Will ProSTUD Drywall Framing be available nationwide?

Yes, all ClarkDietrich Building Systems manufacturing facilities will produce ProSTUD Drywall Framing.

When will ProSTUD Drywall Framing be available?

The first manufacturing facility conversion will take place in the 4th quarter of 2009, with the entire conversion process taking approximately six to eight months. All ClarkDietrich manufacturing facilities are now producing ProSTUD.

Can ProSTUD Drywall Framing be mixed with UltraSTEEL?

Yes, the ProSTUD Drywall Framing studs and track are fully interchangeable with UltraSTEEL components and will still achieve UL fire ratings (specific tested assemblies must be supplied as specified).

Is ProSTUD Drywall Framing code compliant?

ProSTUD Drywall Framing meets or exceeds all local building codes and is thoroughly UL fire tested. See ProSTUD's Code Approval page for more information.
