Scott – 3 rails will be fine, but your footings are only about half as deep as they should be…seriously…
If I were doing it – it’d be 900mm minimum.

Scott, robs thread here should be helpful if u missed it. i was wondering if your using channel and clips?

ill take your word then (better to be safe than sorry) also there will be cars parked by the side of the sign
anyone recommend a seller. (on the posts/rails)
priced the job on a quote of Blackburn metals.

Try (your local) Righton for the whole lot – panels, rails, clips, posts, baseplates, caps…

yes channel and clips.
blackburn quoted me on the system.
not that its hard to tape and rivet the rails. they recommended me to have 500 mm in the ground with base plates.

will give them a ring now

Scott,
David is right about the size of footing. If you install this with only 500mm support, the local prevailing wind conditions could give you a problem. The V board could under certain conditions become like a giant sail, with no where for the wind to spill, thus your turning moment becomes greater than the force holding it in the ground.
The other factor to consider is ground condition. If the ground has been recently disturbed, the natural soil compression could be compromised. I know its a pain going to that depth, but it is better to be safe than sorry.

What I’ve taken to doing is getting these building / construction / property companies to dig their own holes and line them with a slightly oversized drainage pipe.
They dig a huge hole with some machinery, insert the pipes to my specified depth, concrete & backfill.
I turn up a day or so later – drop the poles into the now perfect cores – level out if needs be with a few rocks thrown in the hole…wedge vertically in place with a thin strip of wood hammered down the side & backfill it with quickset / post cement. Dry mix down the gap & pour in the water…sorted.
The last time I was digging holes (about 2 feet deep) was in a car park through tar & chunks of rubble with a 2 man post coring tool…not really into long hours of manual labour in a hole in some field if I can help it.
:lol1:

as you can see in my mock up iam attaching 2 signs to the front pole to make the "v" shape
is this possible?
looking at robs demo he has used 2 poles?

You will need to "stagger" the rails Scott. By that I mean make sure the rails are at a different height on each panel otherwise they will prevent you from mounting two panels both at the same height on the centre post. It can be done though and the tripod arrangement will make it quite stable. You can improve the stability further by bracing the two outer posts together (to form a closed triangle in plan view). Do this simply by attaching sign channel rail between the two outer posts using conventional post clips.

^^^^what he said^^^ 😛
Same principle if you are doing back-to-back panels on a pair of poles.

not if you use these Dave(bottom of page 1)http://www.rennicksuk.com/uploads/File/Brochure.pdf
But i have to agree 500mm is not deep enough mor like 900mm / 1000mm especially with 4mtr posts

I Spent 18 Years installing signs Neon, Fascias, Canopys Etc and One little tip on fitting signs like this is when you buy your concrete buy a few breeze blocks or bricks. Like has been said dig the holes 3 foot deep and wedge half pieces of block around the post on all four sides of the square hole. Level up the sign and really hammer in the blocks, this way the sign will stand up on its own and should be quite firm. You can then make slight adjustments to the level of the posts. Then fill with concrete. This way the sign is standing up on its own perfectly solid and will not move so you can be confident that it will stay in this position while the concrete sets after you have left.
