If I am purchasing any equipment to roll wire mesh and the diameter of the steel wire in the mesh is 4mm.........then I can tell the manufacturer that I rolling a mesh with either an 8 or 9 gauge steel.
Correct?

Yes ish Standard Wire Gauge (English) wire 9G = 3.6576mm 8G = 4.0640mm
AWG 6 = 4.114mm 7 = 3.657mm

There are two different measures:(I assume that steel wire is what you are talking about)
steel WIRE gauge: measured in mm or inches and is the Diameter in tenth of an inch.
steel Sheet gauge: measured in mm or inches, and is the thickness.
your closest WIRE gauge to 4mm would be .160" there are 4 different wire gauge standards.
1.American Wire Gauge (AWG) or Brown and Sharpe..This will be 0.162" or 4.1mm or gauge 6
2. US steel wire or Washburn & Moen......................This will be 0.162" or 4.1mm or gauge 8
3. British Imperial std............................................This will be 0.160" or 4.0mm or gauge 8
4.Birmingham or Stubs Iron....................................This will be 0.165 or 4.12mm or gauge 8
They are all very close, and are between wire gauge 8 and 9. , 6 in the case of Brown and Sharpe
When ordering, ask your supplier which standard they comply with. It will differ basically as per the origin of this wire,or where was it made.
Important note: All these measurements are for NON-Galvanized or non coated wire. As mesh producer, I guess you are using Galvanized wire. The Galvanization thickness (X2) must be added to find the finished wire OD. It can also be calculated as the addition of weight per unit length.
Well good luck in your new venture. (Alaskan crabs?)
Last time I was involved in a similar thing, we used a product call Hercules wire which was a blend of Manila wire rope and S.S cable woven together. they had to be submerged for longer periods, up to several years, and it did work very well. (Port entrance protection, part of submarine warfare system.) but we didn't have to be economical... another design that I did, and that was never used due to price,(Non Military) was a submarine alarm system against seals attacking Salmon cages (Southern Chile). The seals were trying to pull the fish out of the cage, and were cutting the nets, putting the salmons under stress and all sorts of problems...Being protected animals, there is very little you can do against them.
I will bet you that the Chinese product will have a lot to be desired, and that you won't be able to bit their prices either...Again good luck.
I could be totally out to lunch... but it seems to me that boat makers use zinc (the stuff used in galvanizing) as a sacrificial anode to keep SALT WATER from corroding other metallic parts of the boat (such as bronze propellers) by galvanic reaction. The "zincs" have to be replaced periodically. In other words, you might want to look seriously at the wire you are using. The galvanizing might go away real quick leaving you with rusting steel wire.
Now I confess that I first heard of the nautical problem in a Tom Clancy novel, but galvanic reaction is very real. I must consider this when I design antennas. You might want to look at this.
Also, I am sure that there are others who know more about this than I do. Further comments are welcome.
Zinc anodes are used extensively in marine applications.
These wire frames will go on nets to be used in a fresh water application and the serverity of the use will destroy these nets within 12 months or less.
Thank you for the reply.

We are going to be using the wire meshed tubes for fish traps . We design and build gear for numerous agencies to sample and (research) endangered fishes and such.
These traps are for pallid sturgeon fishes, pallid sturgeons are endangered.
The wire mesh looks good, but I will not know what the quality is until the cages are hauled up and down a few hundred times. My concern is the welded area. Chinese products are a gamble .....some good, some bad......some really bad........
We are going to cover the wire mesh with a 12mm x 18 ply raschel from Fibras Internationales (from your country).
We also used to do some work with Nitto Redes in Iquique. It was a Japanese company that was working with your country .
To this day, I have NEVER found a netting manufacturer that produced the exquisite quality and cost effective HDPE twisted knotless like Nitto Seimo or Nitto Redes. The strongest netting is still Dyneema UC which is produced by another Japanese company, but Nitto still has my vote for cost effective fish netting.
Keep in touch.
