Looking for something thicker than 10mm in corrugated plastic. Brand doesn't matter, but I tried my 3 main suppliers and nobody carries it..... and like normal , they never heard of it, as they don't carry it. My customer is looking for at least 3/4" or even 1" in thickness. I don't have a Grimco catalog, but maybe someone out there has one and can look for me. Also tried Glantz and Harbor.
