Are there any specific rules/regulations/guidelines for hanging stuff
from suspended ceilings? Illuminaires, ceiling speakers, fire sensors
all just mount on the tiles or clip into the latticework but I want to
know about heavier things.

Reason I ask is that I occasionally work for a bloke who always wants to
do jobs on a budget of a fiver[1] so corners are trimmed
enthusiastically. The jobs are to hang 3kg devices off ceilings, be it
plaster, beams or suspended. When it comes to suspended ceilings
everyone else does it by going up to the "real" ceiling above and
attaching a long pole which drops down through a tile.

The "Oh we've always done it this way method" is to place a square of
ply the size of a ceiling tile above one, and mount to that, making a
600mm2 sandwich. I don't like doing it that way, but it does work.

I don't like being ignorant and I don't do crappy bodges[2] so what does
the team think?


[1] I suspect the only work that comes in is because he's so desperate
to be the cheapest going. This works for Tesco but not for specialist
installation.

[2] I do inspired, inventive uk.d-i-y type bodges that you'd all be
proud of!

Where are we going and why am I in this handbasket?

Don't know about any rules and regulations but its a pound to a pinch
of sh*t, that if any of these ceilings collapses and causes injury
to anyone, and this guy has your name and address, then it will be
your arse that will be on the line. Even if you ask him for written
instructions he'll most likely plead ignorance and claim you said
you knew what you were doing, so he just let you get on with it.

Complete luminairs are frequently held by the ceiling lattice - and
those will run to several kg typically.

So 3kg with a board to spread the load (it does not need to be the same
size as the tile, but it helps if it spans the ali struts each side)
will be fine.

(I have hung a video projector from one in the past, and even had a
small form factor PC in another)

If you get to wanting to hang a complete TV or something, then that will
require more substatial support.

They are universal in commercial buildings and hide many services.
There are various types.
They are cheaper to install than plastering etc
There are special light fittings to fit into the ceiling grid.
If there's anything heavy to hang on them,there are extra suspension wires
installed around the object.

Light objects, a hole can be cut in the tile & mounted on the tile
Heavy objects, a tile can be backed with ply.
Really heavy objects, suspended from the roof above.

The tiles may need clips in windy places. (Stops them blowing away)

Clips may also be required to achieve fire resistance; it stops an
updraft from a fire from lifting fire-retardant tiles.

I think they must harbor germs and bugs in hospitals. I don't like the way
some of them "pant" when doors open and close.
