I don't know a lot about wire mesh and I don't have time to get educated. When I did a search you seemed all over the page - so i think your visibility is okay.
As a top tip, when I don't get sales, I do a search. Example: so I struggle with ski suit sales. So I will be taking a look at this later in the year. I search 'retro vintage ski suit' then press 'sold' listings down on the left hand side. There I can see all of the items that have sold in the last 90 days. There I should be able to see what I am doing wrong. One year this happened and I noticed another seller was just saying small, med, large rather than 38" 40" 42" etc. I thought my way was better, but heyho, I swapped to small medium and large and it worked. You have visibility (I think) so see how others are selling.
Just a guess, I noticed that 30m gives a high price. But when I search 'chicken wire mesh 30m' there are 65 results. Maybe people dont like your initial high price - but then, when they look at other sellers choose the 30m option anyway as it is 'most popular'. I see you are in this list of 65. check out the others and try and imagine why buyers chose them.
