Large Sign. Need help calculating pipe size.

  1. Dec 10, 2013 #1
    Building a large sign. I've attached a drawing of what I'm doing. I need to make sure that 8-5/8 pipe is sufficient for sign. I live in Oklahoma and we get some nasty winds as well. Please help. Any suggestions greatly appreciated.

    Your best bet is to look around your neighborhood for a sign with similar area and construction and see what piping support they use.

    You could also pitch your sign project to some local sign company for an estimate and they may show you the piping they will use.

    I am the sign co. This is much bigger than I typically do.

    How did you decide on your piping diameter? Did you use a prior project and scale it up?

    Have you seen any traffic signs of a similar size?

    I'm thinking that you may need two columns instead of one for stability.

    I found a reference to a sign company that has signs with similar sizes:


    You might be able to get a quote from them and ask about the weight of th sign and the piping needed to properly display it.
