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 design@01peer.com or our nearest customer service centre by calling 1300 725 675 for further advice.

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. Peer Industries PIF-MSC-011 Rev 06 28/07/09 Concealed ceiling systems technical manual Page CCS 28 of 47

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. For use in any other design and construction or for any special structure, please contact Peer Design by email design@01peer.com Call one of our customer service centres on 1300 725 675 or visit our web site www.peerindustries.com.au 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 spacing s. 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.
