Sign tray suspended between posts
Hi all.
We have been asked to tender for a lot of large signage boards, majority of which are folded sign trays suspended between stainless posts.
In the past we would of just farmed this all out to a fabricator but we are interested in moving a lot of this in house.
I have an idea how to fabricate the trays but am stuck on the fixings between the posts and the trays. They need to be fixed to the posts, then fix through the edges of the trays with like a spacer … I hope all this makes sense!!!?
Any advice would be hugely appreciated!
Many thanks

Quick and easy, I’d just bolt through from the inside of the tray into square posts. Tap a thread into the post to take the bolts if the wall thickness is enough or, if not, use captive nuts. Even quicker and easier, use fat hex head self tappers.
I’d only bother with the spacers if there was any likelihood of having to replace the panel at any time. If not, I’d prefer to have the extra rigidity of a larger mating surfaces between tray and post without them.

we just replaced allot of these for a long term customer of ours.
they had been bought in from their southern side of England sign supplier.
the signs were just like you said but not stainless. all alluminium.
the pans had been folded and corners welded, then powder coated.
they had then used tech screws to fasten into the posts from the inside/rear of the trays. each sign had about 4 pan/trays with a two inch space between. they worked well from what i could see, but NOT the way i would have done it. i think doing it this way can open a can of problems when it comes to the guys erecting the posts in concrete if both legs arent fixed together in some fashion to keep them square and perfectly spaced.
that said, they "may" have been pre-assembled before leaving the workshop and laid flat on the rear of a truck while in transit. -
I’ve never done this before but just a suggestion.
Can you bolt or weld two horizontal pieces of alloy, steel etc and then screw in the trays on these? No visible fixings from the front of the sign and easy to replace.

Thank you all for your reply.
They are looking at circular posts but I think we will be drilling and then a captive nut onto the post. Thinking of also using a groundsleeve for the poles to drop into so therefore are hoping to re-use the posts (as they are talking 50+ signs)
Do you then think that a spacer may be good route to go down to ensure any future panels line up?
Also do you think a stand off barrel fixing would be strong enough? the type used on acrylic panels etc…
Thanks again

If you are going down the captive nut or ‘rivnut ‘ route be aware that installing rivnuts above M5 size is very difficult by hand, even if you use aluminium rivnuts. They need to be pulled up correctly otherwise they will turn in the hole and that is even worse in a round tube because there is very little surface area to bit on.
