I'm hoping to produce a frame for some display material. My initial plan
is to
produce a square 'tower' about 900mm square and approx 1800mm high -
effectively two 900x900 frame cubes - strong enough to carry a light
notice
board on each of the four 'faces'.

I'm thinking of making the frame from aluminium square section (1cm
square?)
joined with plastic fixings - square equivalent of the sort of fixings you
get
for gazebos/markees. The construction needs to be set up and dismantled in
minutes, be light, and be constructed of materials that can fit in the
back of
a car. And it needs to be low cost.

NB Using the design described I'd need 20 lengths of aluminium section
88cm
long (having them all the same size helps fast construction) and 12 fixing
pieces.

Q. Am I likely to be able to get such aluminium section and plastic
fixings?
Where?

Any help would be appreciated.

=====================
If you want cheap and cheerful.......

Take four pieces of 2"x1" timber. Drill an 8mm hole in each end. Thread a
length of 6mm polypropylene rope through four holes at one end and another
length through the holes at the other ends. Join the ends of the rope. Take
another two lengths of 2"x1" (each about 50" long for your purpose, I
think) and join them in the middle with a nut and bolt so that they're free
to swivel. Stand the prepared four piece framework upright and use the
prepared swivelling cross to spread the four piece framework. It will be
rather like a giant box kite frame.

Make another of the same size and stand on top. You'll probably need some
kind of locating feet on one of the frames.

p.s. I don't think that aluminium is particularly cheap and finding special
plastic fittings to fit could be problematical.
