help please with fitting site boards?
I am supplying a large siteboard to a customer who is installing it themselves. (Builders so got the equipment!)
It is to be 2 8 x 4 ft dibond panels that are going into the ground on poles and clips with sign channel. Both panels will be on one set of poles, one above the other ………. how far into the ground do you reckon they’d need to be sunk?
Trying to work out what kind of length of poles will be needed ……….. 6m? -

how high off the ground does the bottom of the bottom panel have to be?

Have Signfix/Tofco not got a ready reckoner sort of thing for post depths?
They used to have one for spacing sign channels etc. 🙂 -
Dunno Fred…….. do you have a weblink ?
Sorry George about 6ft from the ground to the bottom edge of the panel.
-
I would say you were about right 6mtr posts with about 1.5mtrs in the ground 😀
-
A 1/3 of the total post height should go underground Marcella, ideally.
But I always usually go under that I would say 12-1500mm will be fine,
5500 – 6000 posts
Love the new pic Georgio 😕 me boy

I agree with Martin.
two panels total depth 2.4m with 1.8 ground clearance
5500mm – 6000mm long steel poles set in the ground around 1200mm, depending on how compact the ground is. assuming that it’s not been recently dug up on somewhere like a building site.
Square steel posts are structurally stronger, although circular posts allow more scope if the posts are not in line correctly when fitted.
p.s. like the classy new photo too 🙂

thanks for all the help guys! 😀 much appreciated.

Of course, nobody has asked the obvious question……
Two posts or three? Or four? 😀

Your post is the 11th by my count John :lol1:
Sorry silly Friday afternoon mood.

I figured it may require 3 …………….?

That’s what I’d do. 😀
So, what size and material because, even with ten metres of post in the ground, if they aren’t strong enough they will just bend at ground level in a wind.
I’m sure there are calculations for this sort of thing but I’d left school by the time they got around to that. 😀

Ashby will tell you what you need via a quote.
They have the windage software. -
If I am not sure about this sort of thing I normally give Ashby a phone for a quote as Peter says they have the software to calculate wind loading so will be able to quote you both number and diameter of posts required.
I would think you would be looking at 3 x 114mm posts at 6 metres in length but you may find they need to be the next size up.

that’s exactly what I was thinking.
Ashby might be helpful here 😀
