Siniat steel stud ceiling systems are designed using stud and track horizontally, which are fixed to supporting walls on either side.

They are typically used in corridors, bathrooms, kitchens and fire tunnels and often hide services such as aircon ducting or cabling.

Steel stud ceilings are a good option in situations where it is difficult to install a suspended ceiling system. Steel stud ceilings can be suitable for fire-rated and non-fire-rated applications.

In terms of Section 8 of AS 1170.4 ceilings are a non-structural building component that needs to be designed to resist horizontal and vertical earthquake forces.

Siniat offers two main designs for steel stud ceilings to help architects and designers comply with the seismic design requirements of the particular project - Type A and Type C.

Please note that project details must be determined by structural design and the design of suspended ceilings will require a structural assessment unique to every project.

Type A

The Type A solution for seismic design of steel stud ceilings is constructed with horizontal steel studs. One side is fixed and the opposite side is sliding. Seismic control joints are installed at 12 m maximum intervals.

Construction details are available in the Steel Stud Ceiling section of our technical manual Blueprint for the following options:

• Type A1 - Stud Ceiling 
• Type A2 - Stud Ceiling 
• Type A3 - Stud and Batten Ceiling
• Type A4 - Stud Ceiling

Type C

The Type C solution for seismic design of steel stud ceilings is constructed with horizontal steel studs and evenly distributed 2-way plenum braces. The number of plenum braces is determined by structural design. 

Both sides are sliding. Seismic control joints are installed at 12 m maximum intervals.

Construction details are available in the Steel Stud Ceiling section of our technical manual Blueprint for the following options:

• Type C1 - Stud Ceiling 2-way plenum braced 
• Type C2 - Stud and Batten Ceiling 2-way plenum braced
