I am carving a sign for a church that will be 4'x6'. It will be carved on both sides
I am considering using high dencity urethane board . I am looking at 1.5" thick 18 lb density.
It will be suspended between a post on both ends.
I don't have any experience with this material, and was wondering if it will be strong enough to withstand our strong winds in Nebraska? It will be located in an open area . or will it need to be thicker ?
