You can use that type of fencing to make a gate.
But you have to staple it to the end (hinge) side and then run a t-post or something thru the side you open, and then have a loop of wire at the bottom that you put the foot of the t-post in, then pull the top of the t-post over and drop a loop from the top of the post over it to hold it closed...we have used one like this in the past made out of that woven wire or even out of barb wire as shown in a previous post, but I don't like them..to hard to wrestle around and open and close when I need to get thru in a hurry.
The gate you had a picture of was made from a cut down section of a welded wire fence panel.
What you could do is to replace the big heavy corral panel (it sounds like thats what you are using) with a welded wire panel, normally you can buy a 16 foot one for under 20 dollars. Take some staples and fencing wire and wire the hinge side up off the ground to support the weight on that end and then wire some chain with a latch on the end to loop around the end you open and close...
I use cattle panels for gates on leased land, they work fine. As a matter of fact I have one on the back of our acrage that lets me drive the tractor/mower/rake/baler directly on to the property behind me that I am lucky enough to get to bale and keep the hey on for our cattle.
If you securely wire the top and bottom of the hinge side and then chain the middle of the side that opens to the post on that side, the cattle won't bother it in my experience, and its much lighter and easier to move than a real cattle corral panel.
And its cheap and easy and quick to put up.

That link shows the kind of panel I mean, it's available at most any farm and home store or tractor supply.
I actually have a link to a road gate I made using some of those wedge lock aluminum pieces that let you use t-posts for angle bracing and a welded wire cattle panel for the gate...
