Key facts
Subject to loading detail, suspension should not exceed 1200mm centres
The suspension must not be out of plumb (vertical) more than 25mm for each 150mm of plenum depth and in no case should exceed 500mm to a 3000mm depth
Whenever the above is exceeded and/or when the hanger suspension is more than 2000mm long, then a sub grid is recommended. Should suspension be vertical, then a 4200mm drop would be acceptable using hanger strap
In no case should suspension be from other services in the ceiling void
A hanger suspension point within 400mm from the wall angle or shadow moulding must be installed on main tees and cross tees
Two steel pop rivets with a shear strength three times that of the maximum allowed ceiling load is to be used
When securing wire to tee, it should be wound tightly around itself at least three times
Should the ceiling mass exceed 20kg/m2, a sub grid is required and a consulting engineer should recommend suitable suspension
