Often, if you are sheathing both faces, bridging is not needed. Bracing: Bracing is also a concern, even though non-structural studs are non-load bearing.Note that sheathing provided on one side does not count as composite design. You can build further and taller with composite stud design. You can easily look up load charts for a non-structural stud with no drywall and compare it with one that has drywall on both faces (at full height) you can use a composite stud design table, which means these assemblies have been fastened together, tested in a lab under different conditions, and deemed acceptable for published spans/heights. Tested High Capacities: Non-structural metal studs have high capacities for their small thickness.Note: Iron Engineering does not recommend using 15 mil material because of its extreme thinness. As a designer, you have to pay attention to structural steel strength and ensure your calculations are correct. The ProSTUD 25 is 15 mil and uses 50 KSI on both the track and the stud. The 18-mil track uses 50 KSI steel and the stud uses 70 KSI steel. The 19-mil track is made with 50 KSI steel. The ProSTUD 20 can come in both 19 and 18 mil. The ProSTUD 30 is 30 mil and also uses 33 KSI steel. Using Clark Dietrich as our example, the heaviest non-structural stud is the ProSTUD® 33, which is 20 gauge, 33 mil, and 33 KSI. Strength of Steel: There are typically two strengths of steel when it comes to structural studs: 18 and 20 gauge are often made with 33-KSI steel 16-ga and heavier will be 50 KSI.A deflection track should be used to accommodate movement. This can result in cracked drywall and costly repairs. This happens when the contractor rigidly ties a stud top of wall to the track, which means there is no accommodation for movement (such as snowfall on a roof or people walking on floors) a roof, for example, can move as much as 1” vertically. Fastening Studs to Track: The biggest mistake we see is not using a deflection track when it’s needed at top of walls.
