I don't know if this will be of any help at all, but in all the time that I have kept pigs....
I don't use a feed trough, their food is liberally scattered on the floor - as they are outdoors, it keeps them occupied for quite sometime. Having said that, if/when they have to come indoors, I also feed them on the straw. Any feedtrough will disintegrate fairly quickly when it comes under the onslaught of some very determined piglets.
As for the water trough - this tends to vary with age and size. When they are weaners (8 weeks till about 12 weeks), I tend to use a standard plastic bowl inside a tyre. This gives them something low enough that they can drink out of, while the tyre surround prevents a barrier to them turning it over. Once they are of a size where they can reach, an old belfast sink is ideal, as the smooth surface on the outside again prevents them up-ending it!!
Failing that, a small metal sheep feed trough will always double as a water trough, but it does have the disadvantage of having an edge that they can get their snouts under, thereby allowing them to turn it over!
Hoping that this is of some assistance - best of luck with the weaners.
