WE usually specify schedule 40 or 80 hot dipped galvanized steel for bollards, however we have a client who wants aluminum bollards - this may be a dumb question, but has anyone specified aluminum bollards - do they hold up? What is the thickness of the tube walls? Anything else I should know in specifying them.
Bollards used for vehicular protection are typically concrete filled. Are you sure you want to fill an aluminum tube/pipe with cement?

I don’t, the problem is that the project is in Jamaica and galvanized steel does not hold up, stainless steel is too pricey for this application. Any suggestions??
I guess you could coat the inside with something to isolate the cement from the aluminum… I am told that even the thickness of a kynar coating is enough, but I would rather put my faith in 30 mils of bituminous paint.
Actually the bituminous paint manufacturers only recommend 16 mils DFT in 2 coats, which we thought about using…our bigger concern was whether or not the aluminhum would take the external abuse?
Precast?
Thanks Nathan, that is a possibility worth considering, esp. since there is already alot of precast and cast stone in the job.
Jerome,
There are plastic slip covers available for bollards. I will be back to you ASAP.
Precast concrete bollards are also available.
What is the end use location of the bollards?

Jerome,
I found what I was looking for.
Barco Products, 1-800-338-2697.
111 N. Batavia Ave., Batavia IL 60510
Barco furnishes thermoplastic post sleeves. You may have seen them at a fast food drive through and Wal*Mart.
Available in not 1, not 2, but 3 colors. Yellow, red, and, my favorite, blue.
They have a wide variety of parking lot products.
I hope this helps?
Wayne
Wayne, thanks for taking the time to find this product, but its a bit cheesy for this project. The project is a resort in Jamaica (yes it is Jamaicaning crazy) where you and I may never be able to afford to stay one night, let alone a week…precast may be the best bet, thermoplastic no. Again thanks anyway, I will file this company’s products as I may be able to use them in other future projects.
