    Been researching best substrates for post and panel signs. In the East most available are Grimco Maxmetal, Alumalite or Dibond. Alumalite has a thicker skin than Maxmetal, .012 versus .008. Laminators claim that the polypropylene corrugated core is stronger than a solid polyethylene core. We are using a frame so the edge is not an issue. I have used mostly alumalite in the past and never tried Dibond. What do you'all use for permanent signs?

    ACM with stringers. The difference between the brands is splitting hairs.

    Alumalite or Alumacorr. There is a difference between the solid core materials and the engineered core materials, along with the thickness of the aluminum skin. Texas is right if you are using stringers, but we run 4x8's for a local reseller and they insist on Alumacorr because it's the most rigid. They put it up without stringers - and Nebraska is plenty windy.

    Embarrassing to admit, I have never heard of "stringer", is that another name for horizontal support?

    I use Fiberbrite panels. They will not dent or break down like ACM. Bums (homeless) won't steal them for recycle cash. Great for traffic signs.

    How to do you weld the faces to the frame on a double sided sign like this? Do you do the sides then sand down flush and paint?
