1 SLOTTED STUD WIND-LOAD & NON-LOAD BEARING DEFLECTION WALL SYSTEM U.L. FIRE RATED Head-of-Wall Joint Systems

2 STEELER INC. SLOTTED STUD The STEELER SLOTTED STUD is an innovative and economical light gauge steel framing Head-Of- Wall (HW) Joint System that is Classified by Underwriters Laboratories, Inc. for 500 successful cycles. It is unlike any other head-of-wall assembly currently in the construction industry and can be used for both non-load bearing and wind load-bearing walls. The STEELER SLOTTED STUD has a slot of 2-1/4" which allows for up to a 1" deflection up or down, depending on which Head-Of-Wall Joint System is used. The Engineer of Record shall specify which Head-Of-Wall Joint System to use.

3 Steeler Slotted Stud MODERN, EFFICIENT HEAD-OF-WALL SYSTEMS A cost-effective alternative to slotted track, the Steeler Slotted Stud is everything you need in a Head-of-Wall system. The Steeler Slotted Stud is innovative and economical, as it can be used in combination with track to form both non-load bearing and wind load-bearing walls. It includes a 2 1/4" slot which allows for up to a 2" vertical deflection and is UL fire rated. Substituting Steeler Slotted Stud in place of slotted track can save your project money while still offering the proper deflection your walls require. Easier Install: Steeler Slotted Studs are lighter than conventional studs, meaning quicker installation. The 2-1/4" slot allows is designed for easy fastening. Better Deflection: Steeler Slotted Stud is unlike any other head-of-wall assembly in the industry. Its 2-1/4" slot allows for up to 2" of deflection. Superior Toughness: We use a full zinc coating to greatly minimize rust formation. What s more, the Steeler Slotted Stud is available in gauges from 21 to 12, meaning superior wind load capabilities. Designed for fire & smoke protection: Two slots in the head of each stud means less of a need for fire proofing. The Steeler Slotted Stud offers an effective alternative to standard slotted track. Depending on the specifications of your project, Steeler Slotted Studs can save you big money. Steeler Slotted Studs meet or exceed ASTM A370, A1003, C754, C645, and C955. The Steeler Slotted Stud is UL rated for up to 2 hours. Members 33ES and thicker are engineered to be load bearing and thus structural. Web Size Offerings: 1-5/8, 2, 2-1/2", 3-1/2", 3 5/8", 4", 5 1/2", 6", 8", 10, and 12. Flange Offerings: 1-1/4", 1-7/16", 1-5/8", 2, 2-1/2, and 3.
