It was compiled by msma with assis tance from the association of the wall and ceiling industries international the drywall informa tion trust fund and the northwest wall and ceil ing bureau. Reduces required material. There would be a gap between the studs and the bottom of the purlins and no mechanical attachment from the studs to the track. Manufactured from bluescope steel with a minimum coating of z275.

Provides better load transfer from jamb stud to base track vs. Pre punched 1 slots are spaced 1 o c. Profiles widths range from 51 to 150mm and gauges from 0 50 to 1 15bmt. Flexible track available for curved walls.

You use a track with 2 or 3 flanges and the studs just slide in there. Single jamb stud. 25 and 20 gauge track fastened at floor and ceiling to support the steel studs. Steel stud size is usually derived from limiting height tables based on the capacity of the steel and the allowable deflection of finis h surfaces.

Back to back header reduces web crippling reinforcement requirements. Walls assembled using deflection track are installed similarly to standard load bearing walls with the exception that studs be 1 3 8 shorter to allow for the deflection track s equivalent height. Majority of stud and track is hemmed for safety and increased strength preventing unwanted rotation. It has met the movement and cycling requirements of ansi ul 2079 and is ul classified for 1 2 3 and 4 hour fire resistant ratings in head of wall fire rated joint systems.

Boxed jamb studs welded together reduces material build up and finish problems. Track steel stud p artitions. This article is the first in a series of industry technical notes on cold formed steel con struction. Slotted track scafco slotted track is the industry preferred system for achieving head of wall deflection and fire resistance for interior and exterior walls.

They said they can custom make deflection tracks where the slots would be vertical relative to the slope but you would be better off using the old fashioned deep leg track system. 2 leg height for added strength and improved performance. Allows for fast easy and flexible stud installation. Bell mouthed service holes on 0 50bmt 0 55bmt.
