Once and for all we have lots of good information about PVC. The only area not very well covered is the expansion factor. Knowing it will happen I've made provisions when putting my signs together. Of all the materials I've used, this one has the most advantages. Lets hope the manufacturers will maintain good standards.

I've just received another order for exterior park signs. The size remains the same 28"x78". The color is dark brown. After two years they all look like new.
