Material recommendation for large sign tray
Hi guys & gals, I am quoting on a large sign tray job and was wondering what you would recommend.
The sign will be approx 5400 x 900 x 125mm and will have cut outs where the lettering goes to be internally illuminated.
Which material could I use on this size
1) Aluminium
2) Aluminium compositeI know aluminium will be the better of the two but probably a lot more expensive so if I can get away with composite to give a better/alternative price but only if it is not going to buckle or bow.
What do you think?
Maybe I’m thinking to hard here?!!! (chat.)
:feedback: :cool::thanks:

I’d have said composite every time. Isn’t composite much stiffer than aluminium for a given weight? I think this means it will bow less than aluminium would.
If it’s composite, won’t the tray have a join? This should help stiffen up the face.

Owen, if you are talking about like for like weight then you are probably correct because on a like for like weight the ally would probably be less than a mil thick so at the size Mike wants then it would probably be more flimsy but we aren;t as ally trays aren’t made from such thin material and are heavier in weight that a composite tray.
At that size Mike it is possible for a composite tray to bow but this can be overcome by using some strips fitted inside the tray to help strengthen it and prevent it bowing.
I would be inclined to give them the 2 options explaining the difference in the 2 materials. At least that way you aren’t going to look expensive against someone who just gives them a price based on composite.
