I bought some mesh from Ebay - (they're selling it for $8.95 per yard with free shipping) and I wanted to make sure I got the right thing. It was advertised as 160 (I think it's actually 158 but I don't care about that...)

It occurred to me that after all these years I don't know what all the numbers printed on the edge of the mesh mean. This particular one says "gold - up 64T*55um*158cm 021M." I assume the "158cm" is the mesh count but what does all the other stuff mean?

Actually 110, 158, 200, 305 are "english" not metric so the 158cm wouldn't be that.

64T is  about 160 in US system. 55um is the thickness of the thread.
158cm is probably the width of the bolt (guessing here) and 021M could be some sort of manufacturer's designation.
Somebody else might know more. . .

Yes, we've won our share of awards, and yes, I've tested stuff and read the scientific papers, but ultimately take everything I say with more than just a grain of salt! So if you are looking for trouble, just do as I say or even better, do something I said years ago!

Thanks, I guess I thought the "cm" stood for "count mesh" LOL

I did the math and the metric numbers make sense. 64 threads per cm comes out to 162/ inch and 158 cm would be a 62" bolt.

I'm not sure I've ever seen mesh that didn't have both English and Metric... price seems average

I made a mistake once; I thought I was wrong about something; I wasn't

I haven't either. I thought it was pretty cheap. My local supplier charges $12 a yard and I need to drive into Denver to get it.

You guys are so dead on with the mesh... It's a 158/55 (slightly thinner thread that is usually found in a 180 or 200 mesh count) in a 62" wide roll.

The $8.95 price is pretty typical for a lower end mesh. What you want to watch out for is if the mesh is a LOW elongation mesh or not. If it doesn't specifically say low elongation, it will just keep stretching and stretching until it has no tension. This means having to push harder and harder to clear the screen.

I can't match the price and the free shipping, but if you want a really great quality mesh, I have a 158 that I can match the price on if you're willing to pick up the shipping. Just shoot me an email if you want - ron@shurloc.com

the 21M is most probably the length of the bolt in Meters,   starts at one and goes up.
Most of the mesh we buy has this printed on it.
