INSTALLATION
1
Mark the position on walls for the finished
ceiling height, taking into account the thickness
and number of layers of plasterboard to be
used. Fix the GTEC T-Bar Edge Channels TE3000
to walls at 600mm maximum centres (short
length uppermost).
2
Attach GTEC Soffit Cleats to the structural soffit at 1200mm
or 900mm centres depending on the load along the axis of
the Main T.
Cut lengths of GTEC Metal Angle equal to the drop of the
ceiling, from the GTEC Soffit Cleats to the start of the
horizontal flange (minimum drop 50mm).
Fix GTEC Metal Angle to GTEC Soffit Cleats with appropriate
Nuts and Bolts (GTEC Soffit Cleat is not required for timber
joist floors). For timber joists, fix GTEC Metal Angle direct to
sides of joist with a minimum overlap of 50mm using a
minimum of 2 GTEC High Thread screws. (Min 25mm depth
into timber).
NOTE: As an alternative, GTEC Hanger Wire or strap hanger
may be used instead of GTEC Metal Angle.
3
Fix the GTEC T-Bar Primary Main T TP3700 to
the GTEC Metal Angles with 2 GTEC Pan Head
Self Tapping screws.
To fix two Main T’s, simply connect together.
It is not necessary to stagger the Main T-Bar
connection.
