Installation and Fastening Sequence for Steel Studs

The first plasterboard sheet installed at a joint should be fixed
to the open side of a stud flange. Additional sheets are then
installed in the direction toward the closed side of the stud web.

When installing the first side, screw-fasten the plasterboard sheets
to studs at edges only, as illustrated in Figure 1 (positions 1 and 2).
Then, on the second side, fasten the edge (position 3) followed by
intermediate studs (position 4). Return to the first side and fasten
sheets to previously unattached studs (position 5).

Figure 3 - Effect of Incorrect Fastening Sequence
Caution
D1 General
Avoid fixing Boral Plasterboard sheets in the direction from the closed
side of the stud to the open side of the stud web (Figure 2). This will
result in the first sheet at a joint being incorrectly screwed to
the flange on the closed side of the stud. The flange will then be
free to deflect when the next sheet is screwed to the open side
(Figure 2). This can permanently bend the flange, resulting in a
lipped joint.
If the stud is not supported firmly while the screws are driven,
the stud can twist from square, also resulting in a lipped joint
(Figure 3).
Do not fix plasterboard sheets in the direction from the closed
side of the stud to the open side of the stud web (Figure 2).
Do not screw the first sheet at a joint to the flange at the
closed side of a stud web.

Correct Installation

The correct direction of sheet installation is in the direction from CORRECT DIRECTION IN RELATION TO STUD
the open side of the stud to the closed side of the stud web Figure 4 - Correct Fastening Sequence Detail
(Figure 4). The first sheet installed at a joint is screwed to the
flange at the open side of the stud. The flange will initially deflect
then straighten as the screw pulls tight. Ensure that the stud
is adequately supported to avoid twisting, and fully screw this Flat Joint
sheet to the stud before continuing. Figure 5 - Effect of Correct Fastening Sequence

The next sheet is now screwed to the flange at the closed side
of the stud. The deflection on this part of the flange is very small,
and the previously installed sheet helps keep the assembly rigid
during the installation of the second sheet.

If fixed correctly the result is a flat joint with no lipping (Figure 5).
The correct installation sequence is illustrated in Figure 5 below.

Do fix plasterboard sheets in the direction from the open side of
the stud to the closed side of the stud (Figure 4).

Do screw the first sheet at a joint to the flange at the open side
of a stud.

The following instructions must be followed to achieve satisfactory results:
• Care should be taken to isolate copper pipes away from contact with steel framing to avoid problems with corrosion.
• Plasterboard linings are not to act as supports for piping.
• Piping is to be kept clear of face sheets and baffles.
• Ensure that baffles protect the areas immediately behind wall penetrations.
• Pipes are to penetrate one face only of the partition between any two wall studs.
• Total area of all openings between any two wall studs must be no greater than 5000mm2.
