how would I go about fitting sign above a fence?
i have been asked to look into fitting a sign above a fence
this sign is roughly 8m x 1500mm
i was thinking of having an angle iron frame made and bolting the legs to the steel fence posts (palisade fencing)
then attaching a dibond sign to the angle iron frame
any advice from anyone who has done something similar or do you know of a sign system which is actually designed for this purpose?

I’d forget attaching to the fence direct as the wind force on the sign might weaken the fence, if theres some room posts and signblanks from ashbys might be a better bet

hmmm i wasn’t sure about putting my own posts in as wouldn’t that just be duplicating the posts that are already in the ground?
do the fencing posts not have a structurally sound footing that would be good enough?

8m x 1,5m is a lot of extra area and at ahigher height than the fence = extra leverage, you can make your own judgement call but I like to err on the cautious side and sleep nights 😀

I am with John 100% on this one. New posts which are up to the job is definitely the way to go. Ashby Trade or similar will be able to advise you what is needed re dia of posts.

Again, I agree with the guys. If you fit your own posts you know that the depth is right for the signage.
My garden fence blew down in the storms earlier this year and I’m certainly glad there wasn’t a 8m sign attached!
Good luck!

fence posts are fitted differently to sign posts. normally shallower in depth into the ground and less concrete around the based. fences like this do not have anywhere near the wind load of a large sign.
even if the fence stands upto the pressure, will your fixings from the fence to the new uprights holding the sign hold out? ide say not…if your customer wants the sign fitted correctly you will need to erect a series of free standing plastic coated sign poles into the ground, approx a metre deep. you will need a "minimum" of 3 posts per panel… 8-11 posts over all… 4-4-3 or 3-3-2 posts (your call)
you will need sign channel on the rear of the sign panel around every 16-18 inches down the depth of the sign and by the full length of the sign.
you will need post clips then to fix in place.remember base plates and caps for your posts…
ide recommend sand, chips and cement and mixing by hand/mixer as opposed to the likes of post-fix…. post fix is fine for smaller signage. but has no real body to it so better mixing on site. buying the mix from a merchant will work out a fair bit cheaper than the likes of dozens of bags of post-fix from b&q.
remember and hire a Cat-Scan from your local toolhire company… scan the ground in case you hit any cables. wear rubber palmed gloves also… just in case.
this may all sound like over kill to you, but im only just giving you the bear basics here…
your customer may grumble at the costs, but its better paying to get it right, than paying low and it coing down in the next high wind. because rest assured, if it does, your doors the first one getting knocked by your customer. god forbid it coming down on someone, then again, your customer will point the finger at you!
hope this helps…
