Maximum suspension centres should only be considered for lightweight* installations. Emac hangers should be installed a maximum of 300mm from the end of a run of Emac channel and 300mm from the joint between these channels. Where two spring tees meet and are spliced together, an Emac channel should be installed within 500mm. It is considered good practice to stagger joints in supporting structures.
When supporting services such as downlights, speakers, detectors and other mechanical and electrical services, the maximum load applied to the ceiling tile must not exceed 2.5kg including spreader yokes if applicable. The SAS pattress system allows the integration of heavier items by distributing the load back to the Emac Spring Tee. The pattress can accommodate a load of up to 6kh and are available in sizes to suit all standard modules. For load greater than 6kg we recommend independent suspension. Pattresses are available in sizes to suit all standardmodules.
