- 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.
