Steel Studs for Non-Loadbearing Interior Walls⁽¹⁾
Forming Part of Sentence 9.24.2.1.(1)

Notes to Table 9.24.2.1.:
(1) The values in the Table are based on a single layer of 12.7 mm gypsum panel sheathing installed on each side of the studs. Where one side is not accessible, gypsum panels on only one side will suffice. The values are also based on attaching gypsum panel sheathing using screws not smaller than No. 6 spaced at a maximum of 300 mm at edges and at intermediate supports.

1. Except as required in Article 9.24.2.4., steel studs in non-loadbearing interior walls shall have a metal thickness of not less than 0.46 mm.

1. Runners for interior and exterior non-loadbearing walls shall have a thickness not less than the thickness of the corresponding studs and shall have not less than 30 mm flanges.

1. Where openings for doors in non-loadbearing fire separations required to have a fire-resistance rating do not exceed 1 200 mm in width,
   1. the width of steel studs shall be not less than 63 mm, and
   2. the metal thickness shall be not less than 0.46 mm.
2. Where openings described in Sentence (1) exceed 1 200 mm in width,
   1. the width of steel studs shall be not less than 91 mm, and
   2. the metal thickness shall be not less than 0.85 mm.
3. The distance to the first stud beyond the jamb of any door opening in a fire separation required to have a fire-resistance rating shall not exceed 400 mm.
4. Where the distance between the framing over the opening referred to in Sentence (3) and the top runner exceeds 400 mm in such walls, intermediate support shall be installed at intervals of not more than 400 mm above the opening.

1. The size and spacing of non-loadbearing steel studs for exterior walls shall conform to Table 9.24.2.5.
