The company I work for has 10 plants and a couple distribution centers. While shipping might take awile (until space is available on a truck coming this way) the cost is very acceptable (free)
If mesh were a solid to microwave then hole diameter would not matter
Sadoun would sell 1' mesh dishes. We will most likely always differ on this particular subject because I just flat prefer solid one piece dishes. The bigger the better. But cost wise I am getting 8.5' mesh dishes for free pretty much anytime I want one. That is why you find mesh dishes in my yard. The last solid one I got was 10' but warped by the folks that took it down. They didn't want it anymore and did not care how it came down.
