System 330 Installation Advice
Lay-In Tiles, Profile Suspension
NotesEmac hangers should be installed a maximum of 300mm from the end of a run of Emac channels and 300mm from the joint between these channels. Where two C-Profiles meet and are spliced together, an Emac channel should be installed within 500mm.
It is considered good practice to stagger joints in supporting structures.
Additional LoadsWhen supporting services such as downlights, speakers, detectors and other mechanical and electrical services, the maximum load applied to the ceiling tile must not exceed 7kg including spreader yokes if applicable.
The application of a load should always be considered. Please consult the SAS technical department for further advice.
For loading for flange formed reinforced apertures, please consult with the SAS technical department.
Suspension OptionsC-profile suspension brackets can be used with Emac channel sub grid or threaded rod.
A single threaded rod can be used with C-Profile widths of less than 150mm, wider C-Profiles require two threaded rods for stability. A distancing profile must be used when using the following system 330 applications for lateral restraint and integrity.
