Alumacorr vs. Polymetal

[rlmercer]

Trying to decide which is more durable for a permanent 4' x 8' sign (mounted between posts): 10mm alumacorr or 1/4" polymetal. I generally lean towards polymetal for my signs, but was wondering the pros and cons of each.

Thanks!

I'd say alumacorr

with polymetal you would want to use a MDO or other exterior ply backer

My problem with fluted core is it dents easily. Might not be an issue in NC or CA, but around here signs near the road get dented from flying gravel and snow plows throwing crap at them in the Winter.

I lean toward ACM panel secured on at least 3 sides, no MDO backers. I slot the posts and bottom (and top if not shaped) cross member so a good 1" or more is secured inside the posts and framework.

poly metal much more durable

polymetal with a couple 2x4 stringers behind it for structural stiffening

I'd go with Alumacore. It's more rigid. I think polymetal is too floppy for that size.

Polymetal is the same as Maxmetal, I have a lot of 4'x8s on post without any plywood backing on them here in Chicago and I never had one come back as of yet.

Thanks for all of the input, guys. I'm going to try out the Alumacorr on this one and see how it holds up.

we find this to be the best method.

have never been impressed with alumacorr

We've had alumacorr delaminate..
