1) Steeler C-H Studs conform to the manufacturers standard gauge (MSG), shape, and section property specifications listed in each UL/USG system design and Fire Resistance Rating and are therefore acceptable for use with listed wallboard gypsum products bearing the UL classification marking.
2) The 2 1/2" web X 1 1/2" flange dimension for C-H Studs is a minimum requirement and larger sizes, i.e.; 4" and 6" (studs) are permitted system stud sizes under any UL certification.  
3) All wallboard sizes specified in each system design must bear a UL classification marking.
4) Note specific manufacturers standard gauge (MSG) and stud length (floor to ceiling) requirements in each system design.
5) Note "J" shaped floor and ceiling runners (J Track) require unequal leg lengths of 1 in. and 2 in. and manufacturers standard gauge (MSG) requirements may vary by system design.
