So I went down and picked up the wire, so far not too happy

, first off I had to get 100' of it, then I was going to get the none galvanized type so I could use it for birds but was told it would not last long, and as there was serval rolls of it with rust wile the other was new looking I figured it was the better choice, found out though that it is coated in Zinc! but it is made for use on rabbit cages so? Then when I got home and took off the plastic found the edges were very sharp on the sides and there are lots of sharp bits on the one side were the welds are wich I thought the galvanizing was too eliminate? As I cant return the mesh and am pressed for time I have started make the first cage, 36"X18"X36", by bending the wire into a square then fastening on a top and bottom and probably a few shelves as well for added support, so far I have the sides bent and the top/bottom cut, mabie I should document it with pics? Can anyone give me any advice on the following;
If the rough/sharp sides of the wire is faceing out should it be safe?
Do chips tend to shew on the mesh a lot?
Is a wire bottom ok for them or could they develope foot problems?
Can babies get threw 1"X1/2"??
