bluejan I suppose it depends on variety as to spreading, I was concerned when I planted mine but they haven't spread much at all in 7 yrs. I have one with pale green/ golden canes and a black one. I'm sorry but I can't remember the varieties, don't even know if there is more than one black one.
The reason I asked about metal was I was thinking about big old plastic buckets, like you get Growmore in, wide but not mega deep.
If you want bamboo for it's looks ok, but if you want a quick screen ( black grew the slowest ) have a look at Arundo Donax ( Spanish reed grass) it grows very quickly, big chunky hollow canes, it does throw up new shoots from the earth each year but are easily snapped off. If it gets too congested they will bend over and snap off. I use the ones removed for all sorts, bean supports etc.
Hope you find what you need.
