opinion .25" alumalite

[Marlene]

I usually use .375" thick to make a 4' x 8' sign between posts but because I want t use the ivory and it comes only in .25", what's your opinion on using that thickness at 4'x 8' between posts? too thin? using U-brackets to mount to posts

 

[k.a.s.]

That's pretty thin IMO, can you run a 2x4 along the bottom edge? It would probably be ok with some support along the bottom.

it's double sided so I thought about running a top and bottom bar between the posts and attaching two single sided signs to that. guess that will be the plan. thanks

bottom and top 2 X 4.......then find center of the 2 X 4's........get some 3/4" X 1" trim boards, drill holes bout every foot, run 2 lengths of that on both 2 X 4's leaving a 1/4" opening for the alumicore to set in.....same top 2 X 4 and bottom one. i have done a few of these and even here in florida with high winds.....it stayed put.

.25 board

gentlemen-
all good points for mounting. i used a "L" bracket running down the side after using just 4 mounting clips. the wind snatched that sign right off the posts and moved it down the street.
i would def. use some kind of trim bevel going across.
i recommend...
In the porch section of home depot, they have lattice holders for decks. this gives a nice groove for alumilite to run across after installing that to the posts, top and bottom!

Depends on budget.
Two panels glued back to back with a 4' angle on either side to mount to posts works.

Check a few more suppliers it should be available.

If not, double sided MDO and a couple coats of paint....

If it's just a site sign or otherwise not "pretty" sign, using large fender washers (1") when screwing it to the posts works just fine. I've never had one tear off, even in 80 mph winds.

this is a single 3mm panel, 2 sided sign, done exactly how old paint described....

use a 2x4 across the top and bottom, set the bottom 2x4 on something similar to this..

I think if I use the ivory, I'll just make a couple of pans from .040 and make the usual inner structure from 1" x 1" square aluminum. it was wishful thinking on my part that .25" would work.

If I remember right, the 1/4" Alumalite is rated for over 100mph winds. (Don't think the one sided Econolite has this rating.)
I have made several signs using this material with no supports top or bottom.
I put about 2" deep slots in the posts to slip the ends of the sign into. Then put about three lag bolts through the
post, slot and sign to secure it on each end.
Makes it difficult to remove the sign though, unless you cut the slots all the way to the top of the post to slide the sign
out.
