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.

There are commercial display products that do what you want, but definitely
not at low cost. Nothing to do with commercial display equipment comes at
low cost. You will have to design and make your own if you want that. Bamboo
is light and strong and could be made a feature of the display, perhaps it
could be pushed into holes drilled in solid plastic balls for the joints.
