the nice thing about C & C cage is that u can do lots of things with it. I separated my male from my females with it and use carton wrapper to wrap each grid and then wrap it some more with transparent tape, in the end it will have a smooth look and be very tough for pigs to bite through and can't even climb on it. My male piggy was a biter so at the sixth month of changing liners and some space started appearing he managed to get a biting space but still couldn't bite through so that's one idea, another one is to use table covers, harder to manage but sturdy, there's also waterproof bedsheets and whatever u can use at home that u can find and wrap around the C&C cage to separate the boy from the girls but I recommend a transparent one to let the piggies interact even while separated and makes reunion much easier. I'll attach some photos here. (I didn't try this but seen some youtube videos of people using shower curtain covers, they also meet the requirements)
