help with high hoarding sign versus strong winds
Hi All I have a sign to to fit which would be a a hoarding sign 2 boards each at 7.5foot butted together to make a 15 foot sign. This sign is straightforward to make.
however the customer has a scissor lift so i can get to the top to fit the sign on the building
what i need to know is how would i enforce the sign or what would be the best way to make sure the wind does not blow it off?? i am thinking brackets but what type and how??
here is the picture of the building. it will be fixed to the 3 poles on top with addional brackets behind which is what i am thinking. I saw one sign quite large about 10x5ish blown off from the scaffold. i can only imagine that could have hurt someone so am a little afraid and want to make sure the job is done properly and safely.

We did one a few months back it was very similar to that.
In the end my husband fixed painted plywood to both the front and the back of the poles, then screwed the sign to the front boards making sure some of the screws went into the poles.
Can you imagine the tea time conversations we have……. every likely I reach for the wine LOL

Overkill is the key to this one! Make it out of solid aluminium and but some very hefty fixings. Price accordingly and don’t be shy about it. If you do it cheap and it blows down it could do some serious damage or hurt someone.

Thanx guys for your replies
So Denise im assuming you mean plywood sheets behind the poles and in front of the poles and then the sign in front of the front ply sheet, then bolted altogether through all sheets. is that right??
is that right??
also if done this way i assume there would be no need for brackets. is that correct??

Supply only….back away, develop a fear of heights, say your legs fell off unless you are prepared to do some serious overkill, belt & braces job as that flying through the air isn’t a scenario you wish to contemplate.
Sure, the poles are up the the job…but what are they fixed to and will THAT take the wind load & vibration of 100mph winds?
Also, as suggested, backing it all off in ply with fixings bolted right through the poles & board.
…and make sure you have your public liability insurance in order!

Yes he did that, as said before belt and braces. as it was an engineering firm we did it for, he also advise a diagonal brace to help with wind… 😀

Unless you know what you are doing and you know it will stay up…which sounds like you don’t……. Walk Away, you’ll sleep much better at night.
