Concealed Ceiling Steel Products
The Peer Industries concealed ceiling system utilises furring channels, top cross rails, rod and
suspension clips to provide a flush ceiling finish.
This concealed ceiling system is versatile and provides many options to the user.
These concealed ceiling systems have been designed to meet Australian and New Zealand
Standards together with sound engineering principles substantiated through laboratory tests.
Ceiling Systems are not Trafficable unless stated, and are
designed to carry the weight of the ceiling only.
The Peer concealed ceiling system can be used in both fire rated and non fire rated situations
using appropriate plasterboard or other suitable cladding materials.
Peer Industries concealed ceiling systems can be used to build either a typical ceiling or an
acoustically rated ceiling by using appropriate plasterboard.
Acoustic ceilings with a specific STC rating can be achieved by using furring channel with
resilient mounts and appropriate plasterboard.
This suspended ceiling systems manual is designed to provide a general guide to the design and
application of Peer Suspended Ceilings.
For more information or design assistance related to systems outside those covered in this
design manual, contact Peer Design by email on [email protected] or our nearest
customer service centre by calling 1300 725 675 for further advice.

Peer Industries C79S multidirectional clip was designed specifically to make building a non
standard (square or rectangular) ceiling easy
The C79S clip is a multidirectional clip that will allow 360
degree rotation of furring channel to top cross rail.
This clip has been specifically designed to address the problems
encountered in the construction of irregularly shaped non
square or rectangular ceilings.
The use of this clip will simplify the construction of difficult
ceilings and result in significant saving in construction time
The C79S clip has been extensively load tested and complies
with all relevant standards.
The C79S is manufactured from the highest quality corrosion
resistant zinc plated steel available and is covered by Peer
industries standard product warranty.

(6) Typical Concealed Ceiling System - Ceiling Joists
Refer to Fig 20
Electrical, mechanical and plumbing services can make suspended ceiling systems difficult to install. The height of a project can also render the installation of a suspended ceiling system uneconomical. To solve this problem Peer steel studs can be used as ceiling framing members in areas such as corridors and bathrooms.
Refer to span table CS-01 for ceiling joist sizes and spacing.
Mark position of tracks at ceiling level on wall as per working drawings.
Fix these perimeter tracks with appropriate fasteners close to stud (ceiling joist location) at 600 mm
maximum centres.
Cut the studs to required length.
Fit the studs in to the tracks.
Provide and fix bridging members at the location as per table CS-01
Install ceiling lining board as per manufacturers specification.

Installation contd
Curved Ceiling
Install curved TCR25 top cross rail as per ceiling framing plan and in accordance with the
above ceiling installation details and appropriate bracing with brace.
Install FC28 furring channels at a spacing to suit the radius of the curved ceiling with Peer
furring channel to top cross rail C39 (locking key) clips
Secure the C39 to the TCR with a screw fastener to prevent slipping.
Refer to plasterboard specification of curved ceiling for spacing of furring channels.
Raked Ceiling
Install TCR38 top cross rail in raking position as per ceiling framing plan and in accordance
with the above ceiling installation details and appropriate bracing.
Install FC28 furring channels at spacing to suit ceiling lining thickness with Peer furring
channel to top cross rail C39 (locking key) securing the C39 to the TCR with a screw
fastener.
Refer to plasterboard specification for spacing of furring channels.
Lining to Ceiling Frame
Plasterboard Installation
Cut the plasterboard sheets to size.
Position the sheet with the recessed edge at right angles to the framing member.
Press sheet firmly against the adhesive (if it is to be used - see manufacturers
specifications) and fasten at the centre line of the sheet on every framing member as
shown in fig 07.
Use full sheets.
Saw cut sheets around openings.
Butt joints must be staggered and not in a straight line across the ceiling.
All plasterboard installation should be in accordance with AS 2588 & AS 2589 and the
manufacturers specifications.
Peer Industries PIF-MSC-011 Rev 06 28/07/09 Concealed ceiling systems technical manual Page CCS 28 of 47
Installation contd
Other Building Board Installation:
All building board installation should be in accordance with the manufacturers specification
and recommended installation methods.
Expansion and Control Joints:
Expansion joints as well as control joints must coincide with those structural control joints
provided in the main structure.
Control joints shall be provided in long continuous ceiling at 12 metres maximum spacing.
Refer to Figs 25, 26 and 27 for control joint at perimeter, parallel to furring channel and
perpendicular to furring channel.
Storage and Site Handling:
Where possible all material used in the construction of steel ceiling framing should be
handled in a manner that reduces the risk of damage. All material should be kept in a dry
area so accidental damage cannot occur.

Design
Notes
Span tables are prepared for the use of top cross rails, furring channels, top hats and ceiling
battens that are manufactured by Peer Industries Pty Ltd.
Tables are based on permissible stress loading calculated as per
AS1538 - 1988 Cold Formed Steel Structures Code
AS2785 - 1985 Suspended Ceilings Design and Installation
Deflection = As specified under tables
Yield stress = 300 Mpa
Section properties are based on the full section, using the nominal section dimensions
notations which are in accordance with AS 1538.
Refer to the sectional properties tables for full details of all products
All information contained in this brochure is intended as a general guide only for use in
ceiling framing construction.

Almost all structures will deflect during service.
Ceiling designers should be aware of the expected deflections of the building structures as
they affect the ceiling.
These deflections may be due to both dead and live loadings.
In fire rated ceiling framing, thermal expansion of steel frames should be expected during
fire service.
Designer should make due allowances for these effects.
The ceiling designer should properly consider framing design and layout around openings in
ceiling systems.
Ceiling spans are determined by various design criteria including: weight of ceiling, wind
loading, deflection limits, material size and required spacings.
For span information to satisfy specific design criteria contact Peer Design.
Some examples detailing various component scenarios have been provided to assist in the
choice of the correct product for most building projects.
